N-β-(Aminoethyl)- γ-aminopropyl methyldimethoxysilane

Formula :          NH2(CH2)2NH(CH2)3Si(OCH3)2CH3

Solubility

WD-53 is easily soluble in water with spontaneous hydrolysis occurring. Caution: Due to solution enthalpies mixing water is exothermic. Always stir WD-53 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 WD-53 is easily soluble at differing levels. With ketones and various halogenated compounds a slow reaction can occur. Towards acids, epoxides or isocyanates WD-53 shows typical amine function. Some nonferrous metals can discolor upon contact.

Applications

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

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

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