    98% Min Purity Amino Silicone Oil Colorless Liquid 0.965-0.975 Specific Gravity

    AminAmino silane coupling agent 3-(2-Aminoethylamino)propyl-dimethoxymethylsilane:


    Chemical name: 3-(2-aminoethyl-3-aminopropyl)methyldimethoxysilane


    It is a colorless, strongly alkaline liquid with amine smell being very sensitive to hydrolysis. It is a diamino-functional silane capable of providing good adhesion and superior elougation and flexibility at the polymer-substrate interface. It is used to promote adhesion between glass, mineral and metal surfaces-reinforcements, fillers and substrates-and resins that react with amino groups in systems such as PVC plastisol, polyurethane, or epoxy-based adhesives and sealant, or in phenolic and epoxy molding compounds. Its reduced alkoxy functionality might also be useful in waterborne systems such as latex coatings, adhesives and sealants, providing lower reactivity and therefore higher stability in the aqueous environment.

    It is easily soluble in water with spontaneous hydrolysis occurring. Caution: Due to solution enthalpies mixing water is exothermic. Always stir it into water. With alcohols miscibility is, in general, possible with self-catalyzed exchange of the alkoxy-groups. In aliphatic and aromatic hydrocarbons and (moisture-free) ethers or esters it is easily soluble at differing levels. With ketones and various halogenated compounds a slow reaction can occur. Towards acids, epoxides or isocyanates. It shows typical amine function. Some nonferrous metals can discolor upon contact.


    Provides superior elongation, flexibility and spreading at the interface as a coupling agent.

    Improves adhesion between glass, mineral and metal surfaces and amino-reactive resins.

    Improves adhesion, while maintaining good shelf stability as an additive in waterborne systems.


    Silane coupling agent is available in 200kgs iron drum,1000kgs IBC drum or other packing on request.


    Caution During Transportation: UN NO: 3267; Hazard Class : 8; Packing Group: III

    Keep container tightly closed and store in a cool, well ventilated place.

    Shelf life

    Original characteristics remain intact for 1 years, if kept in recommended storage.
