Product Information

Chemical Name：VINYLTRIS(β-METHOXYETHOXY)SILANE

Product Code：LT-172

Molecular Formula：C₁₁H₂₄O₆Si

Molecular Weight：280.4

CAS NO.：1067-53-4 

Properties and Reactivity

LT-172 is a coupling agent containing vinyl functional groups, which improves bonding between unsaturated polyester resins or cross-links polyethylene resins, elastomers and inorganic substrates including glass fibres, quartz, silicates and many metal oxides.

In the presence of moisture the methoxyethoxy groups of LT-172 hydrolyze to produce β-methoxyethanol and reactive silanol (Si-OH) groups which can bond to a variety of inorganic substrates or react with each other to form siloxane bonds (Si-O-Si). The organophilic vinyl end of LT-172 can also react with a suitable polymer (activated by peroxide or radiation).

Technical Data

Application

→ LT-172 is used as an efficient adhesion promoter for various mineral-filled polymers, improving mechanical and electrical properties especially after exposure to moisture.

→ LT-172 is used as a co-monomer for the preparation of different polymers such as polyethylene or acrylics. Those polymers show an improved adhesion to inorganic surfaces and they can also be crosslinked with moisture.

→ LT-172 is used to improve the compatibility of fillers with polymers, leading to a better dispersibility, reduced melt viscosity and easier processing of filled plastics.

→ LT-172 is used to pretreat of glass, metals, or ceramic surfaces, improve the adhesion of coatings on these surfaces and corrosion resistance.
