Introduction:                                                          

KH-792(equal to A-1120, GF 91, KBM603) is a clear, colorless, strongly alkaline liquid with smell being very sensitive to hydrolysis. The chloride content ranges in the lower ppm-level.              

KH-792 is used as adhesion promoter at organic/inorganic interfaces, for modification of surfaces(corrosion prevention, component of primers) or silicone-polymers or as crosslinker(moisture crosslinking of polymers). The application as coupling agent leads in general to an improvement of mechanical and electrical product properties above all under exposure to heat and/or moisture.

 Solubility:           

 KH-792 is unlimited miscible with water with spontaneous hydrolysis occurring. Caution: Due to solution enthalpies mixing water is exothermic. Always stir KH-792 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-792 is easily soluble at differing levels. With ketones and various halogenated compounds a slow reaction can occur. Towards acids, epoxides or isocyanates KH-792 shows typical amine function. Some nonferrous metals can discolor upon contact.

 Applications:

Excellent integral adhesion promoter for Epoxy, SPURsm, MS Polymer? RTV Silicone and PVC-based sealant.

Useful component in primer systems for hybrid, SPUR, MS Polymer and polyurethane sealant.

Additive to phenolic binders for fibrous insulation.

Additive in phenolic and epoxy moulding compounds.
