Application
1. Crosile® 1891 3-Mercaptopropyl)triethoxysilane is a kind of multifunctional silane coupling agent that is mainly used to improve the cohesiveness between the fillers containing hydroxyl groups and unsaturated polymers having double bonds.
2. Crosile® 1891 is able to improve physical and mechanical properties of vulcanizates. Crosile® 1891 can markedly improve tensile strength, tearing strength and abrasive resistance and reduce compression set of vulcanizates.
