3-Glycidoxypropyltrimethoxysilane is a bifunctional organosilane with three methoxy groups on one side and an epoxy ring on the other.
The methoxy groups bind well with glass substrates creating a 3D matrix.
The epoxy group is reactive with amides, alcohols, thiols and acids.
3-Glycidoxypropyltrimethoxysilane is highly reactive in water and can be used as a linking agent between the surface of the silica and the polymeric matrix.
Application of 3-Glycidoxypropyltrimethoxysilane
3-Glycidoxypropyltrimethoxysilane is widely used as a silica precursor. GPTMS alone with tetraethylortosilicate (TEOS) can be blended with chitosan for use as a filler for polymeric scaffold for bone tissue engineering.
3-Glycidoxypropyltrimethoxysilane can also be coated on the surface of aluminium alloy to protect from corrosion.
3-Glycidoxypropyltrimethoxysilane can used to functionalize (wrap) multi-walled carbon nanotubes (MWCNTs) which can be used as s a reinforcement in epoxy matrix nanocomposites.
Pre-treatment of carbon steel with 3-Glycidoxypropyltrimethoxysilane enhances the dry and wet adhesion while reducing the cathotic disbondment rate of an epoxy coating.
Physicochemical Properties of 3-Glycidoxypropyltrimethoxysilane
Colorless transparent liquid;
Soluble in a variety of organic solvents;
Easy to hydrolysis;
Able for condensation to form polysiloxanes;
Easy to polymerize in the presence of overheating, light and peroxide.
3-Glycidoxypropyltrimethoxysilane is the first widely used coupling agent and has been used for 40 years.
One end of its structure with reactive groups such as amino and vinyl, can react with epoxy, phenolic, polyester and other synthetic resin molecules.
The other end is alkoxy (such as methoxy, ethoxy etc.) or chlorine atoms which is connected with silicon.
These groups can be transformed into silanol in the hydrolysis in water solution or damp air.
And the formed silanol is able to react with surface hydroxyl of glass, minerals and inorganic filler.
Therefore, 3-Glycidoxypropyltrimethoxysilane is commonly used in silicate-filled epoxy, phenolic, polyester resin and other systems.
3-Glycidoxypropyltrimethoxysilane can also be used for FRP production, in order to improve its mechanical strength and resistance to wet environment.
The organic groups of the silane coupling agent are selective about the reaction of the synthetic resin.
Generally, these organic groups lack sufficient reactivity with synthetic resins such as polyethylene, polypropylene and polystyrene, and thus the coupling effect for them is poor.
In recent years, new varieties of 3-Glycidoxypropyltrimethoxysilane with better coupling for polyolefins have been developed, but are limited in cost and other properties and are not yet widely used.
3-Glycidoxypropyltrimethoxysilane is also known as silane treatment agent.
Its general formula is Y (CH2) nSiX3.
Wherein n is an integer of 0 to 3; X is a hydrolyzable group such as chlorine, methoxy, ethoxy and acetoxy; Y is an organic functional group such as a vinyl, an amino, an epoxy group, a methacryloyloxy group and sulfydryl.
Uses of 3-Glycidoxypropyltrimethoxysilane
3-Glycidoxypropyltrimethoxysilane is an epoxy-functional silane, it is a clear, light straw liquid.
3-Glycidoxypropyltrimethoxysilane may be used as a coupling agent in polysulfide and polyurethane caulks and sealants, in mineral-filled or glass-reinforced thermosets and thermoplastics, and in glass roving size-binders.
3-Glycidoxypropyltrimethoxysilane is particularly employed as an adhesion-promoting additive in waterborne systems, e.g. improving the adhesion of acrylic latex sealants.
Applications of 3-Glycidoxypropyltrimethoxysilane:
3-Glycidoxypropyltrimethoxysilane may improve dry and wet strength in cured composites reinforced with glass fiber rovings.
Enhance wet electrical properties of epoxy-based encapsulate and packaging materials.
Eliminate the need for a separate primer in polysulfide and urethane sealants.
Improve adhesion in waterborne acrylic sealants and in urethane and epoxy coatings.
3-Glycidoxypropyltrimethoxysilane is mainly used in unsaturated polyester composites to improve the mechanical properties, electrical properties and light transmission properties of the composites, especially to improve their performance in wet environment.
In wire and cable industry, when used to treat EPDM system stuffed by pottery clay and crosslinked by peroxide, it can improve consumption factor and specific inductance captance.
Used for its copolymerization with monomers like vinyl acetate and acrylic acid or methacrylic, to form the polymers widely used in coatings, adhesives and sealants, providing excellent adhesion and durability.
3-Glycidoxypropyltrimethoxysilane is used in the production of carbon steel and its pre treatment favors the dry and wet adhesion of epoxy coating.
3-Glycidoxypropyltrimethoxysilane is also used to prepare epoxy-functionalized silica nanoparticles, which gives a reactive surface for one-step and high-density protein immobilization.
3-Glycidoxypropyltrimethoxysilane serves as a coupling agent and adhesion promoter.
