Coupling agent

Organofunctional alkoxysilanes are used to couple organic polymers and inorganic materials. The typical feature of this application is enhancement. Such as: glass fiber and mineral filler mixed with plastic and rubber. They are used with thermosetting and thermoplastic systems. Mineral fillers, such as: white carbon black, talc mother, wollastonite, clay and other materials are added directly in the mixing process or pre-treated with silane or in the compounding process.

By using organofunctional silanes on hydrophilic, non-organic reactive fillers, the mineral surface becomes reactive and lipophilic. Applications of fiberglass include car bodies, ships, showers, printed circuit boards, satellite TV antennas, plastic pipes and containers, and others.

Mineral filling systems include reinforced polypropylene, white carbon black filled molding compounds, silicon carbide grinding wheels, pellet-filled polymer concrete, sand-filled casting resin and clay-filled EPDM wires and cables, as well as used in automobile tires, shoe soles, and machinery Materials and other applications of clay and white carbon black are filled with rubber.

Adhesion promoter

When used to bond paints, inks, coatings, adhesives, and sealants to adherents and primers, silane coupling agents are effective adhesion promoters. When used as an overall additive, silane must migrate to the interface between the adhesive and the processed material to be effective. When used as a primer, the silane coupling agent must be used for inorganic materials before the product is bonded. .

In this case: Silane is in the best position (in the interface area) as an adhesion enhancer. By using the silane coupling agent correctly, even under harsh environmental conditions, it is difficult to adhere to oil, ink, paint, and adhesive. Mixtures or sealants can maintain adhesion for a long time.

Sulfur water, dispersant

Siloxanes with hydrophobic organic groups attached to silicon atoms can impart the same hydrophobic characteristics as hydrophilic inorganic surfaces. They are used as permanent hydrophobic agents in construction, bridge and deck applications. They are also used in hydrophobic inorganic powders to make them flow freely and easily dispersed in organic polymers and liquids.

Crosslinking agent

Organofunctional alkoxy silanes can react with organic polymers to bond tri-alkoxy alkyl groups to the backbone of the polymer. The silanes can then react with water vapor to cross-link the silanes to form a stable three-dimensional siloxane structure. . This mechanism can be used to cross-link plastics, especially polyethylene and other organic resins, such as acrylic resins and urethane rubbers, to give paints, coatings and adhesives durability, water resistance, and high temperature resistance.
