D/W
213
PRODUCT DESCRIPTION
D/W 213 is a film skived from virgin PTFE, that has been etched on one
side with Sodium Naphthalene (D/W212) after which a primer has been
applied to enhance bonding to elastomers and pressure sensitive adhesives.
This surface treatment allows the PTFE which normally exhibits very
poor adhesion to be bonded to other materials. The primer may be specified
by the end user or may be recommended by DeWAL for specific applications.
APPLICATION
INFORMATION
The primary applications for sodium etched PTFE involve bonding to elastomers
to produce laminated diaphragms, as well as the applicaton of pressure
sensitive adhesives in the production of PTFE pressure sensitive tapes.
