NECAL 8194 Pressure Sensitive Adhesive      Print Friendly Version

Adhesive Description:

NECAL 8194 is a supported pressure sensitive adhesive that has been designed for high performance requirements in “membrane switch” applications.

Features:
NECAL8194 exhibits excellent diecuttability and shows no adhesive ooze even after extensive aging.  Adhesion is good to most substrates exhibiting repositionability due to lower initial tack but will build to a superior bond after 24-48 hours.  8194, with excellent heat, UV and chemical resistance, is recommended for high performance applications.

Physical Properties:
Composition: Acrylic based adhesive
Release liner: Available with P, W, H, HD, VF liner
Thickness: Total construction 5.0 mil
Scrim: .001 gauge polyester
Adhesion (PSTC-1 std.): Initial: 80-100 oz./in.  Aged: 170-180 oz./in.
