1.Product Introduction of the (N,N-Dimethyl-3-aminopropyl)trimethoxysilane(CAS:2530-86-1)

(N,N-Dimethyl-3-aminopropyl)trimethoxysilane(CAS:2530-86-1), Our model SCA-A81M ,SCA-A81M is a monoaminosilane. Its molecular structure has a tertiary amino group and three hydrolyzable alkoxy groups-methoxy groups. This dual reactivity allows it to pass through inorganic materials (glass, metal , Filler) and organic polymer (thermosetting resin, plastic, elastomer) two-way chemical reaction to improve the degree of bonding, adhesion and compatibility between the two, thereby improving the mechanical properties of the resin-based composite material or improving the resin coating The bonding strength and water resistance of the performance. In different applications, it can be used as a coupling agent, adhesion promoter, curing agent, surface modifier of pigments and fillers, etc.

SCA-A81M is trimethoxysilane, its hydrolysis rate is faster, can provide faster reaction and curing speed, but the side reaction of its hydrolysis reaction is methanol, which is slightly less environmentally friendly.

Q1what is the purity we can supply?

A1:For (N,N-Dimethyl-3-aminopropyl)trimethoxysilane(CAS:2530-86-1), we can supply 99% purity.

Q2 what should we pay attention to when use the (N,N-Dimethyl-3-aminopropyl)trimethoxysilane(CAS:2530-86-1)?

A2:The hydrolysis reaction of SCA-A81M will occur automatically in the presence of water, without the need to add acids as a catalyst. The pH value of its hydrolysate solution is alkaline, in order to obtain a more stable hydrolysate, it is recommended to adjust the pH value of the hydrolysate to about 4.

This product will react with ketone and ester solvents, so it is not recommended to dilute this product with the above solvents.
