Application and Adhesive Selection: Chris has used his experience in adhesive formulating, material
selection, market studies, and environmental testing to help clients
determine appropriate adhesives for various end use applications.
This has included establishing adhesive design criteria and formula
selection for applications requiring oxygen and water vapor barrier
properties, specialty pressure sensitive adhesive applications that
had to adhere to difficult surfaces, and medical device adhesives
that had to meet specific light transmission requirements. He brings
to this area more than 30 years of experience and more than 10 years
Many companies are purchasing coated webs, manufacturing coated webs,
or are considering backward integrating their operation to produce
their own coated webs. Chris has served as a consultant to companies
purchasing coated webs, helping them set up purchasing specification
and in-house quality control procedures. For companies in the business
of coating webs, Chris' service has been in the form of helping them
develop new products, provide an objective outside opinion on new
ventures or capitol improvements. Some companies, having determined
that it may be to their advantage to manufacture their own coated
webs (backward integration) have used Chris to specify equipment,
participate in vendor negotiations, train the operators, and provide
startup assistance. Chris has more than 30 years of experience in
coating and laminating working for companies such as Fasson and Zimmer
Paper Products. In addition he has more than 10 years of consulting
into this industry.
Facility: In some cases companies adding
new equipment or product lines require new manufacturing facilities
(i.e. building, coating equipment, QC labs, etc.), Chris has helped
a few companies with overseeing the complete project under budget
and on time. He has worked with general contractors and subcontractors.
Machinery: Chris has designed coating
machinery for various coating applications and those designs are
still being used today. As National Sales Director of one of the
major machine builders and as President of another, Chris has considerable
experience in coating machinery design. In addition, as a long time
consultant to the coating, converting, and laminating industries
he has a deep understanding of the processes involved which has
allowed him to apply that knowledge to coating machinery.
Material: Chris has formulated barrier
coatings, pressure sensitive adhesives, release coatings (both silicone
and non-silicone), and hot melt coatings. For further information
Acetate Hot Melt Adhesive
Process: The application of the coating
to the web is the heart of any coating operation. Chris has had
extensive experience in a number of coating methods: roll coating,
reverse roll, direct roll, 5-roll multi-roll, three roll offset,
offset gravure, slot, die, pressure, saturators, rod, and Meyer
rod coating. He has been used extensively to help advise companies
on determining the best coating method for a given application and
in laying out the best coating line configuration consistent with
the customers needs. In addition, Chris' knowledge of coatings,
coating rheology, materials, and his application experience has
enabled him help a number of companies with the processes of coating.
Property: This is the functionality required
of the coating. Chris has developed several test methods for the
release and pressure sensitive markets to determine if the products
meet the end use requirements.
Weight: This is the amount of coating
applied to the substrate and is normally expressed as weight per
unit area (i.e. grams per sq. meter). The ideal coat weight varies
by application and at times it is the lowest possible weight and
in other conditions there is a very narrow window for good performance.
Chris has had considerable experience in determining the ideal coating
weights and in explaining the conditions affecting the target range.
Drying and Curing of Functional Coatings:
Using heat and various alternate energy forms (including UV and Electron
Beam) a functional coating is either dried, cured or a combination
Half of all coatings applied to webs require
either a drying process or a curing process. Chris, through his experience
in a wide range of coating operations has worked extensively with
the drying and curing processes and has used a number of key experts
in this area.
Acetate Hot Melt Adhesives: EVA hot melt
is the most common packaging and laminating hot melt. The EVA provides
excellent flexibility and is soluble in paraffin wax. EVA hot melts
not only can bond to a wide variety of surfaces (with the addition
of suitable resins) but also can provide both water vapor and oxygen
barrier properties. Chris has been involved in the formulating and
application of EVA and EEA hot melts since 1969.
Laminating Process: This is the lamination
of two or more films and at times with the inclusion of a metal
foil. Some of the processes are called Triplexing, Solventless Laminating,
Chris has been involved in the adhesive
lamination of films and foils since 1969. With the advent of solventless
adhesives using a four roll coater for the adhesives application and
lamination, Chris has had increasing involvement with the coating
application and equipment design.
Coating Materials: This covers a wide
range of materials including various papers to a number of new films.
The design of a good product requires the best choice in both functionality
and cost. Doing this well requires knowledge of available materials
and a strong network of resources who can help narrow down these
choices. Chris has both the experience as well as the network to
help clients determine the material that will best fit their needs.
Coating Process: The application of coatings
using a gravure coating cylinder. The gravure cylinder is etched
with cells that contain a precise volume of fluid.
The variations in gravure coating are: Direct
Gravure, Reverse Gravure, and Offset Gravure. Chris has work with
all of these methods in a number of different conditions.
Melt Adhesives: This is a class of thermoplastic
adhesives that have a blend of good properties at reasonable costs.
Chris has been formulating and using hot melts for over 28 years.
He organized and chaired the first Pressure Sensitive Hot Melt conference,
and has done considerable work in this field.
Pressure sensitive labels have been one of the fastest growing packaging
and labeling segments. This technology continues to be refined and
developed. Chris has been in the unique position of managing a pressure
sensitive coating operation, consulting into this industry, and providing
sales support into various label houses. For more information see:
Paper, film, and foil laminating is a critical process and is involved
in many of the converting processes. If not done properly curl, wrinkles
and high waste result. Chris brings to this area more than 30 years
of experience and more than 10 years of consulting. He has been involved
in projects from solving field problems to helping customers select
the best equipment for their operation.
Coatings : There are a number of chemistries
that are used to coat films and webs in the manufacture of medical
devices and drug delivery systems. Chris has worked with a broad
range of coatings such as acrylic transdermal PSA adhesives, high
viscosity coatings, and very thin film specialty coatings.
Coating Materials: Much of the coating
materials and webs required for medical devices are very similar
to traditional coating materials. As a consultant, Chris has worked
in solving coating and laminating problems relating to the manufacture
of several medical devices. This has included special testing devices
and transdermal drug delivery systems.
Products: In recent years there had been
an increasing use of traditional coating and laminating
methods to produce medical products for drug delivery
and medical device construction. Combining the extensive experience
Chris has in special coating conditions and methods with the specific
product knowledge has provided faster market introductions
at lower costs.
As VP of Operations for Zimmer Paper Products, as a consultant to
several paper mills, and in his capacity of specifying and selling
paper and film finishing equipment, Chris has significant experience
with the finishing processes including score, crush, and razor blade
slitting; the use of driven and undriven lay-on rolls; center winding,
surface winding, and center/surface winding.
Sensitive Adhesive: Chris has been coating
and developing Pressure Sensitive Adhesives (PSA's) since 1969.
As Project Manager at Riegel he developed some of the first PSA
Hot Melts. At Zimmer Paper Products he established their PS program,
at Kleenstik-Fasson he over saw the development and manufacture
of PSA coated products. He has extensively consulted into this area
covering formulations, application technology, process control,
Sensitive Adhesive Coating and Laminating :
This is the application of an elastomeric self adhesive coating
to a moving web and the subsequent lamination to a protective face
For more than 25 years Chris has had varying
degrees of contact with this industry: 10 years consulting to PSA
companies, VP Operations to a major PSA converter, and coating equipment
Product Incoming Inspection : Chris has
worked with the test methods developed by the TAPPI and TLMI organizations.
In addition he has simplified some of the methods for quicker response
times and has developed unique test methods for silicone cure.
Product Industry Marketing: Roll products
covers a very wide range of possible end uses. Chris has provided
marketing assistance and marketing reports in the areas of Roll
Label Face Stock, Thermal Transfer Label Stock, and general market
overviews for the roll label industry.
Coating Process: Roll coating typically
refers to variations of smooth roll coating. This
would include three roll direct coating for high
viscosity coatings, three roll reverse for improved coating smoothness
on webs that can handle the increased stress and shear, four roll
coating for 100% solventless laminating adhesives, and five roll
coating for very low coat weights such as those used in solventless
silicone coating. In addition roll coating can refer to gravure
(direct and indirect), and offset gravure which are listed separately.
Chris has over 27 years experience in roll coating, from very low
coat weight applications on delicate webs such as ¼ mil polyester
and .00035 Al foil to heavy (15 mils) coatings on
vinyl for special industrial applications. In his work as a consultant
he has worked on almost every category of application.
Coating Material: As the primary release
agent for Pressure Sensitive Adhesives, silicone coating materials
are an essential ingredient to the PS lamination. Chris began working
with silicone release agents in 1969 as manager of a release coating
group. In 1972 Chris again focused part of his attention to the
technology of coating silicones which included their chemistry and
cure properties. While at Fasson he was able to do much additional
work on silicone chemistry, coating methods, and production difficulties.
Silicone coatings are supplied in three
forms; solvent, 100% solids (solventless), and emulsion. Until recently
emulsion silicones were used only for non critical applications. Today's
latest chemistries have provided release ranges and product consistency
that allow emulsion silicones to be used for premium roll label release
agents. Chris has worked with and continues to work with emulsion
silicones as well as solventless and solvent based
Contamination: In paper and film coating
the silicone coating is cured into a macromolecule. Incomplete cure
results in free silicone that can contaminate surfaces that it is
in contact with. Chris has been involved in a number of studies
on the relative effect of this silicone on various adhesives and
the effects on downstream properties such as die cutting. In addition
to the direct contamination due to uncured silicone there is also
the condition during solventless silicone coating at high speed
where the silicone coating forms a mist that can also be a contaminate.
Chris has limited experience in controlling silicone misting.
Coating Process: This is the application
of coatings and adhesives through the use of a slot die. Slot coating
was developed in 1967 by George Park. Chris worked on the first
slot coater in 1969 at Riegel Paper Company. Since then he has chaired
a number of conferences on high viscosity coating, and consulted
on high viscosity coatings. Through his frequent lectures, consulting
assignments, and close relationships with all of the equipment manufactures
and key adhesive suppliers, Chris remains one of the leaders in
the field of high viscosity coating, particularly hot melt coatings.
Adhesive: In solvent adhesives, Chris'
experience has been in the field of pressure sensitive adhesives.
In the 1980's he was involved in formulating solvent PSA adhesives.
Since then his work has been in the application and testing of solvent
Adhesives: The delivery of medical compounds
through the use of special adhesives has grown exponentially as
the efficacy and ease of use of skin delivery systems are documented.
Chris has had many years experience in the process technology for
the manufacture of these products as well as the particular adhesives
Web (material) :
Coating Process: Chris has spent over
27 years in the web coating process. He has experience in wax coating,
hot melt, solvent coating, solventless coating, and emulsion coating
on a wide variety of webs from light weight films and foils to SBS
boards and heavy films and vinyl's. He has worked with companies
in the USA, Canada, England, Scotland, Finland, France, Denmark,
Web Coating Process
The proper tension control, tracking, and rewinding is critical to
producing an acceptable finished web product. Chris has extensive
experience in determining proper web handling conditions, trouble
shooting web tracking problems (see Web Tracking), and setting the
proper taper tension on the rewind for different web materials. He
has served as a consultant for companies in reducing waste due to
improper web handling conditions.
Handling System: In order to provide
the maximum control over the web, the equipment used for web handling
(unwinds, nip rolls, drag brakes, coating process, oven conditions,
laminations, and rewinds) should be considered as a system. As a
consultant Chris has helped companies specify and select their equipment
and on existing installations he has provided a survey of the system
along with recommendations.
Web Tracking: A number of factors affect web tracking: machine alignment, web condition
(baggy edges, wrinkles, etc.), tension control, web slip, surface
friction, differential draws, spreader rolls and devices (such as
bowed rolls). Chris has worked with all of these factors in his roles
as consultant and the several production positions he has held.
Machine: As a category this separates
web processes from sheet fed processes. See Web Coating, Web Handling,
and Web Tracking for more information
of the critical aspects of winding is the taper tension profile. Chris
has had significant experience in developing optimum winding profiles
for difficult to wind materials such as silicone coated papers and
