Crosile® Sulfur Silane Coupling Agent
Product Introduction
Functional sulfur-containing silanes are widely used in rubber processing, adhesives, composite materials, metal surface treatment, and construction waterproofing, among other fields. Sulfur silanes, which are a type of functional silane with sulfur as the main functional group, are the most widely used functional silanes. They are primarily used in the rubber industry, where they can effectively enhance the bonding between carbon black fillers and rubber molecules an promote rubber vulcanization. Additionally, they have coupling agent, accelerator, and vulcanizing agent properties and have become an important raw material for the production of radial tires.

Application
Sulfur Silane Coupling Agent Crosile® is a type of organosilane compound that contains both sulfur and silicon elements in its molecular structure. As a coupling agent, it is commonly used in the surface treatment of inorganic materials, such as silica, glass, and metals, to enhance the interfacial adhesion between the inorganic material and organic polymers.
The sulfur element in the molecule of sulfur silane coupling agent can react with inorganic surfaces and form strong covalent bonds, while the organic functional groups can react with organic polymers, providing a chemical bridge between the inorganic material and the organic matrix. This chemical bonding improves the mechanical properties and adhesion strength of the resulting composite material.
Sulfur silane coupling agents are widely used in the preparation of rubber, plastic, and composite materials to improve their mechanical properties, such as tensile strength, tear strength, and abrasion resistance. They are also used in the formulation of coatings and adhesives to enhance their adhesion to various substrates.
Overall, sulfur silane coupling agents are versatile and effective tools in the surface modification of inorganic materials, which can improve the properties and performance of various materials and products.
