Covinax 377-00 is a specialty emulsion polymer with very high shear performance and excellent wing-up resistance. Covinax 377-00 can be used in masking and can be used on vinyl films. Covinax 377-00 exhibits1.5 pli average peel adhesion from stainless steel and good heat/humidity resistance. It also shows >10,000 minutes of shear on a 1/2 x 1/2 inch bondline under 500g static load. Covinax 377-00 is FDA compliant under 21CFR 175.105, 21CFR 176.170 and 21CFR 176.180.
A 1 mil (28g/m2) dry film of Covinax 377-00 cast directly onto 1 mil thickness polyester film will exhibit the following average performance properties when tested on #304 stainless steel, which has a #3 surface finish.
A = Adhesive C = Cohesive FP = Fiber pick
PT = Paper Tear T = Transfer
