HENGDA-M8133 - 3-Aminopropyltrimethoxysilane

HD-540
HENGDA-M8133

3-Aminopropyltrimethoxysilane is a chemical compound with the formula NH₂ (CH₂)₃Si(OCH₃)₃. It is used as a coupling agent in various applications, particularly in the field of surface modification and coatings. This silane compound is valued for its ability to improve adhesion between organic materials (such as polymers) and inorganic surfaces (such as glass or metal), due to its silane group that can bond with both types of materials. This property makes it useful in adhesives, sealants, and coatings, where enhanced bonding strength is required. Additionally, it finds application in industries such as construction, automotive, and electronics for its versatility in modifying surface properties.

Applications

1. It can improve the physical and electrical properties of mineral-filled phenolics, epoxies, polyamides, polybutylene terephthalate and many other thermoset and thermoplastic composites. Filler wetting and dispersibility in the polymer matrix can also be improved.

2. In shell molding, the 3-Aminopropyltrimethoxysilane can strengthen the bond between the phenolic binder and foundry sand.

3. As a phenolic resin binder additive, 3-Aminopropyltrimethoxysilane can impart moisture resistance and allow recovery after compression.

4. 3-Aminopropyltrimethoxysilane is an excellent adhesion promoter to consider for use in many coating, adhesive, and sealant systems. With polysulfide, urethane, RTV silicones, epoxy, nitrile, and phenolic adhesives and sealants, the product can improve pigment dispersion and adhesion to glass, aluminum, steel and various other substrates.
