Overview
SP-1055 is a heat-reactive brominated phenolic resin that contains methylol groups. It allows a faster cure of butyl rubbers or other unsaturated elastomers without requiring halogen donors.
Brominated resins are especially useful for applications where the rubber may be exposed to heat or repeated use. SP-1055 prevents quick deterioration by curing or cross-linking.
SP-1055 is also used to cross-link elastomers in the manufacture of pressure-sensitive adhesives. It provides improved cohesive strength while imparting little color to the finished adhesive, allowing high-clarity film formation.
Features & Benefits
- High-temperature stability
- Superior processing properties
- Exceptional scorch safety for a wide processing range
- Supplied in flaked form for easy handling
- Slower cure than SP-1056 due to a lower bromine content
Problems Solved
Scorch safety issues with phenolic or other resins
Low cohesive strength or color changes while curing rubber adhesives
Applications
Butyl rubbers and unsaturated elastomers
Rubber and pressure-sensitive adhesives
