Product description
Structural formula:
Empirical formula:C11H24O6Si
Molecular weight:280.4
CAS No.:1067-53-4
Chemical name:Vinyltris (β-methoxyethoxy) silane
Properties
LT-172 is a vinyl-functional coupling agent that promotes adhesion among unsaturated, polyester-type resins or crosslinked polyethylene resins or elastomers and inorganic substrates, including fiber glass, silica, silicates and many metal oxides. When used as coupling agent, it reduces the sensitivity of the products’ mechanical and electrical properties to heat and/or moisture.
Technical data
Reactivity
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).
Application and performance
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.
LT172 is used to improve the compatibility of fillers with polymers, leading to a better dispersibility, reduced melt viscosity and easier processing of filled plastics.
LT172 is used to pretreat of glass, metals, or ceramic surfaces, improve the adhesion of coatings on these surfaces and corrosion resistance.
Product safety, handling and storage
Customers considering the use of this product should review the latest Material Safety Data Sheet and label for product safety information, handling instructions, personal protective equipment if necessary, and any special storage condition required. The “Best use before end” date of each batch is shown on the product label. Storage beyond the date specified on the label does not necessarily
mean that the product is no longer usable. In this case however, the properties required for the intended use must be checked for quality assurance reasons.
Packaging
