D-130 (SI40) is a hydrolyzable oligomer, which is a mixture of monomers, dimers, trimers, and cyclic polymers. Its average degree of polymerization is 5 siloxane or -Si-O-Si- units. After complete hydrolysis, the SiO2 content is 40-42%. The average relative molecular mass is 750.
Inorganic combination, high UV stability.

D-130（Si40) can be used alone, diluted or as part of a formulated product. Applied to natural stones or other construction materials, it forms a silica-gel like binder (SiO2) that increases the substrate strength.
Polymerization of silicone resins for use in paints and other surface modification applications intermediate for sol-gel process.
D-130（Si40） can be used as a cross-linking agent for RTV-2 silicone sealant .
D-130（Si40) silane provides a scratch-resistant, hard-coat to the finish,On glass and plastic lens materials.
