Covinax 320-10

PRODUCT DESCRIPTION

Covinax 320-10 is an APE- free, formaldehyde-free high performance copolymer, specifically designed for optically clear solvent and moisture resistant removable pressure sensitive applications. This product has been formulated to adhere to multiple substrates. It provides smooth and clean removability with no adhesive transfer or ghosting after extended heat aging on high energy surfaces specifically glass and stainless steel. It is best suited for a variety of markets, from labels and window graphics to specialty tapes. Covinax 320-10 has a good balance of peel and tack adhesion and offers excellent cohesive strength. This product will remain optically clear when exposed to UV. Covinax 320-10 can be repositioned multiple times without losing adhesion and is suitable for re-seal applications where FDA compliance is NOT required.
