    摘要: Provided herein is a pressure sensitive adhesive (PSA) comprising two different acrylate polymers and a metal chelating agent to produce the PSA. The PSAs produced according to the methods described herein can be used under a broad range of working temperatures, i.e., from −99° C. to 40° C., e.g., −40° C. to 37° C. These PSAs demonstrate optimal tack and cohesiveness and/or resistance to warm water bath, when affixed to substrates.

    摘要: Provided herein is a pressure sensitive adhesive (PSA) comprising a polycrylate base polymer, a crosslinker and a fluorescer. The crosslinker does not comprise a metal acetylacetonate, a metal alkoxide, or an alkoxy-metal acetylacetonate, and the fluorescer comprises less than 0.1 wt. % metal oxide based on the solid weight of the adhesive. The adhesive is resistant to yellowing under adverse conditions such as high temperature treatment and/or exposure to UV.
