Abstract
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.
