Epigem offers pilot scale to medium volume film coating and embossing services utilising purpose-built reel to reel equipment, situated in our Class 100 clean room environment. The machine is particularly suitable for polymer film substrates but can also handle metal foils and clean room compatible papers. The equipment can be configured to allow a variety of laminating options before or after coating (pressure sensitive, heat or light curable adhesives). In-line corona treatment prior to coating is available if required to enhance wetting and adhesion.
The coating unit is equipped with a versatile 4-roll universal coating head allowing a number of different coating methods to be used. Wet coating thickness from sub-micron to 100 micron can be applied. The enclosure is fully extracted and materials made up in organic solvents (e.g. MEK, toluene, ethyl acetate) can be used. Application of the coating from aqueous solution or suspension is also an option. The equipment is designed with versatility in mind and so a number of different coating techniques are available.
Laboratory facilities are situated adjacent to the cleanroom for coating formulation, testing and modification
