Crosile® SI28 is a monomeric ethyl silicate, also known as tetraethyl orthosilicate (TEOS). After hydrolysis, it yields 28 wt.% silica, hence the name Ethyl Silicate-28. It has the following chemical formula.
Crosile® 7697 Anchorage Additive is a silicone oil adhesion additive that is a reactive silane mixture, used to improve the wear resistance of silicone release agents or silicone, and the adhesion to the substrate.
Silane Coupling Agent Crosile®970 is 3-Mercaptopropylmethyldimethoxysilane is a bifunctional organosilane with reactive organic mercapto groups and hydrolyzable inorganic methoxysilyl groups. 3-Mercaptopropylmethyldimethoxysilane is a clear, colorless to pale yellow liquid with a slight thiol odor. Soluble in alcohols, ketones and aliphatic or aromatic hydrocarbons.
Crosile® 201 is the basic monomer of the silane coupling agent. The product is colorless transparent liquid. It is insoluble in water and can react with water slowly, but easily to trigger hydrolysis cross-linking reaction in the acid or alkaline environment, which is main basic material used in compounding methoxy silane coupling agent.
Amino Silane Crosile® 550 :gamma-aminopropyltriethoxysilane, a versatile amino-functional coupling agent may be an excellent candidate for use in a range of broad applications to provide superior bonding between inorganic substrates and organic polymers.
A comparative study of α- and γ-functional silane coupling agents in silica-filled SBR vulcanized with conventional sulfur systems shows that the effects of silanes on vulcanization kinetics and their coupling effects depend on their structure and location. Rubber reactive groups. All tested silanes containing mercapto or sulfide functional groups resulted in improvements in tensile properties and affected the cure kinetics of the systems used.
