Applications & Uses
- Applications
- Compatible Polymers & Resins
- Applications
- Mercapto-functional silane used as a coupling agent in polysuflide and polyurethane caulks and sealants
- Useful in sulfur-cured and metal oxide-cured elasomers; Can be either added at the time of compounding or used to pretreat minerals before hand
- Lower levels of this sulfur containing silane are used since it is efficient and fast
- Chemically bonding reinforcing minerals like silica, clay, mica and talc to the polymer matrix; Properties including modulus, tensile and tear strength, heat buildup, abrasion resistance, resilience, compression set and cure time are improved in mineral-filled elastomers
