Silanes Solutions

Full Range of Silanes

Dow Corning offers a full range of silanes including organosilanes and chlorosilanes for applications such as adhesion promotion, crosslinking agents, coupling agents, and hydrophobing.

Organosilanes

RnSi(OR)4-n is the basic structure of organosilanes with "R" being an alkyl, aryl, or organofunctional group and "OR" being a methoxy, ethoxy, or acetoxy group.

The primary applications of Dow Corning organosilanes are:

Aminosilane

• Adhesion promoter, coupling agent, and resin additive
• Improves chemical bonding of resins to inorganic fillers and reinforcing materials
• Used for epoxies, phenolics, melamines, nylons, PVC, acrylics, polyolefins, polyurethanes, and nitrile rubbers
• Surface pretreatment of fillers and reinforcers

Vinyl Silane

• Coupling agent, crosslinking agent
• Used for sulfur and peroxide cured rubber, polyester, polyolefins, styrenics, and acrylics
• Used to copolymerize with ethylene for moisture induced coupling of polyethylene
• Used to graft to polyethylene for moisture induced coupling
• Surface treatment (pre- or in-situ) of mineral fillers in plastics

Epoxy Silane

• Adhesion promoter for epoxies, urethanes, and acrylics
• Surface treatment for fillers and reinforcers

Methacryl Silanes

• Adhesion promoter and coupling agent
• Used for free-radical, crosslinked polyester, rubber, poly(olefins), styrenics, and acrylics
• Used to couple fillers or fiberglass to resins
• Moisture crosslinking of acrylics

Sulfur

• Used as coupling agent for inorganic fillers in sulfur vulcanized rubber mixtures

Alkylsilane

• Hydrophobic surface treatment of fillers and inorganic surfaces
• Silicone synthesis

Phenyl Silane

• Hydrophobic surface treatment
• Hydrophobic additive to other silane coupling agents
• Thermal stability additive to other silanes
• Synthesis of silanes and siloxanes

Chlorosilane

RnHmSiCl4-n-m is the basic structure of chlorosilane with "R" being an alkyl, aryl, or olefinic group.

The primary applications of Dow Corning chlorosilane are:

• Synthesis of silanes and siloxanes
• Protecting agents for intermediates in pharmaceutical syntheses (methylchlorosilanes)

There are eight main chlorosilanes:

• Dimethyldichlorosilane
• Methyldichlorosilane
• Methyltrichlorosilane
• Phenyltrichlorosilane
• Trichlorosilane
• Trimethylchlorosilane
• Silicon tetrachloride
• Vinyltrichlorosilane
