3-aminopropyl trimethoxysilane

RK-G540

Product description

Structural formula:

Molecular formula: C6H17NO3Si

Molecular weight: 179.3

CAS No. : 13822-56-5

Chemical name: 3-aminopropyl trimethoxy-silane

peculiarity

RK-G540 It is an organosilane with an active amine group and a hydrolyzable methoxysilicyl difunctional group. This bifocal structure gives RK-G540 special properties: it is able to organically bond inorganic materials (such as glass, metal, fillers) and organic polymers (such as thermoplastics, thermosets or elastomers) together to promote adhesion, crosslinking agents and/or surface modifiers. It is a colorless, ammoniacal liquid that is soluble in alcohols, chain hydrocarbons, and aromatic hydrocarbons.

Physical and chemical data

Note: The above data is for reference only and cannot be used as technical specifications

Reaction property

In the presence of water, RK-G540 will hydrolyze the silicon hydroxyl groups that produce domestic waves and form bonds on the surface of various inorganic materials. The amino groups of RK-G540 with organic properties can react with suitable organic polymers.

RK-G540 can self-catalyze hydrolysis reaction. The PH of the hydrolysate is about 10. Suitable inorganic materials like: glass, glass fiber, glass wool, mineral wool, silica, sand, mica, aluminum hydroxide, quartz, calcium silicate, kaolin, talc, other silicate fillers, metal oxides and metals. Resins that can be used for RK-G540 include epoxy, phenolic, furan, melamine, polyurethane, PA, PBT, PC, EVA, modified PP, PVB, PVAC, PVC, acrylic and silicone rubber. RK-G540 can react in ketone or ester solvents. The silane itself or the silanized substrate reacts with carbon dioxide to form the corresponding carbonate or carbamate.

Product application

RK-G540 is an important component in many industrial applications, such as:

l Glass fiber/electronic fabric composites: as a whole or as an infiltrating component

l As a primer for glass and metal

l Casting resin: as an additive to cooling cured phenolic resin and furan resin

l Sealants and adhesives: as primer or additive

l Inorganic filled compounds: Pretreatments of fillers or pigments or as additives to polymers

l Paints and coatings: as a primer or additive to improve adhesion to the substrate

The RK-G540 also brings important features to end products, including:

l Improve mechanical properties such as bending strength, tensile strength, impact strength and modulus of elastomers

l Improve moisture resistance and corrosion resistance

l Improve electrical properties, such as dielectric constant, volume resistivity

Improve processing performance, such as:

l dispersivity

l adhesiveness

l Rheological behavior: reduce viscosity, Newton behavior

l Increase filler load
