DF1100 and DF1200 Cementable Adhesive Coated Films
CHEMFILM® DF1100 is a multilayer cast PTFE film, fully fused with one surface modified to render it receptive to many conventional adhesives, elastomers, resins and potting compounds. The surface treatment was developed to assure that its application over pure PTFE would not degrade or discolor the basic film. After surface treatment, the PTFE film loses none of its excellent physical and electrical characteristics, expect that the surface treatment results in a natural color which does not affect any of the desired properties. CHEMFILM DF1200 is DF1100 laminated to 2 mils of acrylic pressure sensitive adhesive. Pigments and other adhesives may be added to individual layers to customize performance. Can be slit or provided as at 20” or 38” rolls
