SCA-A20T 3- (2-Aminoethylamino) Propyldimethoxymethylsilane (CAS No. 3069-29-2) CAS NO.3069-29-2

3-(2-Aminoethylamino)propyldimethoxymethylsilane (CAS No. 3069-29-2), Silane coupling agent SCA-A20T, is a amino-functional silane which acts as an adhesion promoter between inorganic materials(glass, metal, fillers and etc) and organic polymers(thermosets, thermoplastics and elastomers) and as a surface modifier.

1. Sealants: addition to one and two part silicone crosslinked sealants and polysulfide sealants, plastisol sealants improves adhesion to variety of substrates, including glass, metal, concrete and other inorganic surfaces. 
2. Molding compounds: As an additive in phenolic and epoxy molding compounds, reduces the water absorption of molded composites. This, in turn, leads to improved wet electrical properties, particularly at low frequencies.
3. A main material with D4 to synthesize amino silicone oil, a new type textile softener.

Application
3-(2-Aminoethylamino)propyldimethoxymethylsilane (CAS No. 3069-29-2), Silane coupling agent SCA-A20T, is an important additive in many applications. Fexample it can be used as an additive in cold-curing phenolic furan foundry resins to improve the flexural strength of sand/resin elements with very long shelf life of the resins.
Further examples are:
- Glass metal primers
- abrasives: As additive to phenolic resin binders
- mineral-filled composites: Fpretreatment of fillers pigments as additive
- synthesis of functional silicones(amino-silicone oil ftextile auxiliary).
