Sumikaflex 950HQ

Type:

Ethylene-Vinyl acetate-Vinyl ester of versatic acid Terpolymer
Emulsion

Properties:

Sumikaflex 950HQ is a designed grade that has a good contact
adhesive for non-polar materials such as polyolefin. It is used
for adhesive materials of plastic film and foam. For example, it
can be used for packaged adhesives, papers and filmed
adhesives.

Test method
Emulsion was coated to 3 mils thickness on the film. Then, a bondpaper (100 g/m2) was laminated on the film. After 3 days aging atroom temperature, the test pieces were pealed and observed thecondition of adhesive failure.
Water resistance: After test pieces in water for 1 hour, they werepealed with wet condition and observed thecondition of adhesive failure.
