Covinax 234-01 is an APE-free, formaldehyde-free high performance copolymer specifically designed for optically clear, moisture resistant removable pressure sensitive applications. This product has been formulated to adhere to multiple substrates. It provides smooth and clean removability with no adhesion build over time. Covinax 234-01 can be used for wine and beverage labels, window graphics, reseal food packaging, surface protection adhesives, and other label and tape applications. Covinax 234-01 provides the best water blush and water whitening resistance among aqueous adhesives. It has a good balance of peel and tack adhesion and offers excellent cohesive strength. In addition, the adhesive can be repositioned multiple times without loss of adhesion and will remain optically clear when exposed to UV and moisture.

A 1 mil (28g/m2) dry film of Covinax 234-01 DEV 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. Minimum Application Temperature: >32°F N/A Service (Use) Temperature: 20°F to 250°F N/A NOTE: Minimum application and service temperatures are dependent upon many factors including face stock, adhesive coat weight, adhesion, and intended application. We can only offer an estimate based on the Tg and typical performance properties of the adhesive. FDA Compliance: 21 CFR 175.105
Shelf life: Best if used within twelve months of date of manufacture. Mix before use for best results. Product is not freeze/thaw stable.
