Vinylmethyldimethoxy silane, also known as dimethoxy(methyl)(vinyl)silane or simply VMDMS, is a colorless liquid with a pungent odor. Its chemical formula is C5H12O2Si and its molecular weight is 132.24 g/mol. VMDMS is a versatile organosilane that finds application in a wide range of industries, including coatings, adhesives, sealants, and plastics. In this article, we will explore the properties and applications of VMDMS, with a focus on the products supplied by Ningbo Inno Pharmchem Co., Ltd.

Properties of VMDMS

VMDMS is a highly reactive silane that can undergo hydrolysis and condensation reactions in the presence of moisture. Its reactivity is due to the vinyl and methoxy groups attached to the silicon atom, which make it a good candidate for crosslinking and polymerization reactions. VMDMS has a boiling point of 120°C and a flash point of 4°C. It is soluble in organic solvents such as ethanol, acetone, and toluene, but insoluble in water.

Applications of VMDMS

VMDMS is used as a coupling agent, crosslinker, and adhesion promoter in a wide variety of applications. It can improve the adhesion of coatings and sealants to substrates such as metals, glass, and ceramics. It can also improve the wetting and dispersibility of pigments and fillers in coatings and plastics. In addition, VMDMS can be used as a crosslinker for silicone and epoxy resins, which can improve their mechanical and thermal properties.

Coatings

VMDMS is widely used in coatings to improve adhesion, water resistance, and durability. It can be used as a coupling agent for organic-inorganic hybrid coatings, where it can improve the adhesion between the organic and inorganic components. VMDMS can also be used as a crosslinker for epoxy and silicone coatings, where it can improve their mechanical and thermal properties. VMDMS is compatible with a wide range of resins, including acrylics, polyurethanes, and epoxies.

Adhesives and Sealants

VMDMS is used as an adhesion promoter and crosslinker in adhesive and sealant formulations. It can improve the adhesion of these materials to a wide range of substrates, including metals, glass, and plastics. VMDMS can also improve the water resistance and durability of these materials. In addition, VMDMS can be used as a crosslinker for silicone and polyurethane sealants, which can improve their mechanical and thermal properties.

Plastics

VMDMS is used as a coupling agent and crosslinker in plastics to improve their mechanical and thermal properties. It can improve the adhesion between the plastic and other materials, such as coatings and metals. VMDMS can also improve the filler dispersion and water resistance of plastics. In addition, VMDMS can be used as a crosslinker for silicone and epoxy resins, which can improve their mechanical and thermal properties.
