1.Product Introduction of the 3-[2-(2-Aminoethylamino)ethylamino]propylmethyldimethoxysilane(CAS:99740-64-4) :

3-[2-(2-Aminoethylamino)ethylamino]propylmethyldimethoxysilane(CAS:99740-64-4), Our model SCA-A30T , is a triaminodifunctional silane. Its molecular structure has three amino functional groups and two hydrolyzable methoxy groups. This dual reactivity allows it to pass through inorganic materials (glass, metal, filler) Bidirectional chemical reaction with organic polymers (thermosetting resins, plastics, elastomers) to increase the degree of bonding, adhesion and compatibility between the two, thereby improving the mechanical properties of resin-based composite materials or improving the adhesion of resin coatings Strength and water resistance. In different applications, it can be used as a coupling agent, adhesion promoter, crosslinking agent, surface modifier of pigments and fillers, polyurethane blocking agent, etc.

SCA-A30T has three amino groups, including two active hydrogens on the primary amino group and strong reactivity; one active hydrogen on the secondary amino group, low yellowing, and mild allergic response. At the same time, the dimethoxy structure of this product will make the final product 

crosslink density lower than trimethoxysilane, and the product has better elasticity.

3.Application of the 3-[2-(2-Aminoethylamino)ethylamino]propylmethyldimethoxysilane(CAS:99740-64-4):

1. This product is mainly used for the synthesis of high resilience amino silicone oil fabric finishing agent. Because it has three amino groups, the amino silicone oil made has first-class flexibility. After finishing agent made with it, its microemulsion and emulsion can be used as soft finishing agent for cotton, hemp, wool, silk and chemical fiber fabrics, which can make the fabric soft, smooth, fluffy and elastic (its special properties). However, due to the large number of amino groups and the presence of primary ammonia, the yellowing of the product is poor.

2. As an additive or formulated as a primer liquid for polyurethane, silicone, epoxy, nitrile, phenolic, acrylic and other coatings, inks, adhesives and sealants, to improve the adhesion, corrosion resistance, Weather resistance, boiling resistance and scrub resistance, extend the service life, and improve the dispersion and binding of the pigment and filler in the resin phase, which can greatly improve the crosslink density of the product and provide better adhesion to the substrate .

3. As an ammonia curing agent for epoxy modified silicone resin and epoxy resin.

4.Packing Details of the 3-[2-(2-Aminoethylamino)ethylamino]propylmethyldimethoxysilane(CAS:99740-64-4):

The regular packing of 3-[2-(2-Aminoethylamino)ethylamino]propylmethyldimethoxysilane(CAS:99740-64-4) is 25kg plastic pail, 200L steel drums and 1000L immediate bulk container.
