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.
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.
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.
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 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.
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.
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
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 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.
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,
Machine: As a category this separates
web processes from sheet fed processes. See Web Coating, Web Handling,
and Web Tracking for more information
