Everlight Chemical Offers Effective Stabilization for Hybrid Polymer Sealants

摘要

Hybrid polymer, especially Silyl-modified polyether (known as STPE polymers) and silyl-modified polyurethanes (known as SPUR polymers) are the modern hybrid sealants (SMP) which can be used in a wide ranges of applications, such as construction and transportations. Combining the strength of polyether and polyurethanes with the weathering resistance of silicones make these hybrid sealant high performance. But these hybrid sealants also show some disadvantages, for examples: yellowing, chalking, cracking, after exposing under sunlight in outdoors or high temperature conditions after several months. Everlight Chemical Industrial Corp. has a solution to improve the weatherability of SMP sealants by adding Eversorb. HP1. Eversorb HP1 can be used to reduce polymer degradation such as yellowing, cracking, losing mechanical and elastic properties.
