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.
Polymer Type: Acrylic Protective System: Anionic Color: White Viscosity (cps): 50 - 250 (RVF, Spindle #3/50RPM/77° F) Percent Solids (%): 57.5 - 59.5 pH: 4.7 - 5.8 Weight Per Gallon: 8.6 Glass Transition Temperature (Tg): (DSC): -37.1° C
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.
