Tetrapropoxysilane

Description

ChangFu® TPOS functions not only as an effective coupling and crosslinking agent in paints and coatings, but also as a surface modification agent for silica in silicone rubber. Furthermore, it works well as an RTV crosslinking agent. It is also an important precursor for the production of aerogels and silico microspheres.

Features

• High reactivity and lower volatility.

• Excellent wettability and dispersibility.

• Can undergo hydrolysis reaction in the presence of water or moisture.

• High-performance crosslinking agent with adjustable crosslinking degree.

• Good stability throughout storage and use.

Application

• Silane coupling agent and crosslinking agent
  ChangFu® TPOS can be used as a coupling agent, a crosslinking agent and a filler modifier in paints and coatings, adhesives and sealants, electronic and aerospace components industries. 
  As a coupling agent, it can improve the bonding strength and characteristics of many materials. In addition, it is an excellent crosslinking agent, promoting the crosslinking reaction between polymer chains, forming a stable network structure, and increasing the material's heat resistance, weather resistance, and mechanical strength.

• Additive for the synthesis of silicone resin
  ChangFu® TPOS can be used for the synthesis of silicone resin with high temperature resistance performance.
  It reacts with organic molecules like alcohols and acids to form silicate esters and polymers, which are used to make organic silicone resin. This resin has excellent high-temperature resistance, mechanical, and electrical qualities, and is widely utilized in industries such as construction, automotive, and electronics. It can be utilized as a basis material for high-temperature coatings, electrical insulation, and sealing materials.

• Surface modification agent
  ChangFu® TPOS can be used as a surface treatment agent of fibers, ceramics, metals, glass, and other inorganic substrates.
  It can increase the wettability and water resistance of fibers, ceramics, metals, glass, and other surfaces and is used as a surface treatment. It can provide a protective layer on the surfaces of these materials, increasing their weather resistance and longevity. For example, in textiles, it can act as a softener and waterproofing agent for fibers; in ceramics, it can be used as an addition in glaze to improve the glossiness and wear resistance of the surface. 

• Key raw material for construction sealing materials
  ChangFu® TPOS can be used as a key raw material for the production of construction sealing materials.
  It can be utilized as a significant raw material for construction sealing materials, copolymerizing with other monomers to produce sealing materials that are highly weather resistant and chemically stable. These sealing compounds are widely utilized in construction and floor coatings, industrial anti-corrosion coatings, and automobile coatings.
