Covinax 379-05 is a coater-ready surfactant stabilized acrylic adhesive, which was developed for use in permanent pressure sensitive applications. It has excellent wing-up resistance and has found use in pharmaceutical labeling applications requiring adhesion to curved or irregularly shaped surfaces. It has an excellent balance of peel and shear strength, which allows it to be converted into rolls or sheets without sticky edge problems. Covinax 379-05 is specifically designed to be transfer coatable on slot die coaters and may be used on most rod or roll coaters. Covinax 379-05 is FDA compliant under 21CFR 175.105 & 21CFR 176.180.
A 1 mil (28g/m2) dry film of Covinax 379-05 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.
