Overview
SP-1056 is a brominated phenolic resin that is heat reactive and contains methylol groups for cross-linking and curing. It offers a faster cure of butyl rubbers and other unsaturated elastomers without the need for halogen donors. SP-1056 prevents quick deterioration by curing or cross-linking.
SP-1056 can also be used for cross-link elastomers in manufacturing pressure-sensitive adhesives. It provides improved cohesive strength while imparting little color to the finished adhesive, allowing high-clarity film formation.
