Columbus, OH - Label manufacturers who are looking for an invisible pressure sensitive adhesive (PSA) will be glad to see Covinax 462 - a permanent PSA launched by Franklin Adhesives & Polymers, a division of Franklin International.

Covinax 462 is a clear, styrene-acrylic copolymer for permanent pressure sensitive applications that require high water- and blush-resistance. Its high transparency makes it ideal for use in clear film labels used on glass and plastic surfaces, including auto glass and bath and shower product containers.

While Covinax 462 performs well on labels for indoor use, it is also the clear choice for labels that will be exposed to the outdoor elements. It withstands UV, weather and outside exposure without unsightly yellowing or water damage even over time. Lab testing performed with a Colorimeter showed only a negligible increase in yellowing on Mylar and paper.

Although invisible to the eye, Covinax 462 is noticeable for its strength: As a permanent PSA, it offers peel adhesion strength of 2.50 pounds (180° peel adhesion testing), shear strength of 1,251 minutes (178° shear adhesion test) and a loop tack of 2.10 pounds. The high shear properties equate to good high temperature performance in the range of 100 degrees to 150 degrees C.

Covinax 462 also coats well in both direct coating and transfer processes, meeting individual production demands at label manufacturing facilities. It also meets demands for environmental friendliness: Like most pressure sensitive adhesives from Franklin Adhesives & Polymers, Covinax 462 is water-based.

Covinax 462 is one of a broad line of high-performance permanent, removable and specialty pressure sensitive adhesives offered by Franklin Adhesives & Polymers under the Acrynax, Covinax and Micronax brands. These products offer varying combinations of peel, tack and shear strength for specific applications - from packaging frozen foods to labels that can withstand the heat under the car hood.
