KH-602 is a diamino-functional silane capable of providing good adhesion and superior elougation and flexibility at the polymer


Silane coupling Agent KH-602
N-beta-(aminoethyl)-gamma-aminopropyl-methyldimethoxysilane
CAS No.:3069-29-2



Silane coupling Agent KH-602


Chemical Structural Formula: NH2(CH2)2NH(CH2)3SiCH3(OCH3)2

Introduction:

KH-602 is a colorless, strongly alkaline liquid with amine smell being very sensitive to hydrolysis. KH-602 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.

Typical Physical Properties:

CAS No.: 3069-29-2

Molecular Weight: 206.4

Boiling Point<760mmHg>: 265

Viscosity<25>: 4.6mm2/s

Flash Point: 93

Ignition Temperature: 290

Density<25/25>: 0.970-0.980

Refractive Index<25>: 1.445+0.0005

Min. Purity: 97.0%

Solubility:

KH-602 is easily soluble in water with spontaneous hydrolysis occurring. Caution: Due to solution enthalpies mixing water is exothermic. Always stir KH-602 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 KH-602 is easily soluble at differing levels. With ketones and various halogenated compounds a slow reaction can occur. Towards acids, epoxides or isocyanates. KH-602 shows typical amine function. Some nonferrous metals can discolor upon contact.



Applications:

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.
