Covinax 324-00 is a surfactant stabilized vinyl acrylic copolymer used for general purpose permanent pressure sensitive adhesives in tape and label applications. Covinax 324-00 has a good balance of peel and tack, which allows it to be used in a wide variety of applications. Covinax 324 exhibits very good converting properties. It exhibits excellent adhesion to corrugated, polyolefin films, glass and metals. It can be tackified with most of the commercially available tackifier dispersions to tailor tack and peel, but it will perform very well as supplied. Covinax 324-00 is FDA compliant under: 21CFR 175.105, 16CFR 1500.3(C)(4),and 16CFR 1500.3(C)(2)(i).
