Product Description

Abstract
3-Ureidopropyltriethoxysilane (CAS No. 23779-32-0), Silane coupling agent KH-594, is a bifunctional organosilane possessing a reactive organic ureido group and a hydrolyzable inorganic triethoxysilyl group. The dual nature of its reactivity allows KH-594 to bind chemically to both inorganic materials (e. G. Glass, metals, fillers) and organic polymers (e. G. Thermosets, thermoplastics, elastomers), thus functioning as an adhesion promoter and as a surface modifier. KH-594 is a 50% solution of silane in methanol, is a colorless liquid with an alcohol-like odor and is soluble in alcohols, ketones, esters or aromatic hydrocarbons.

Application
3-Ureidopropyltriethoxysilane (CAS No. 23779-32-0), Silane coupling agent KH-594, is an essential ingredient in the products of many industries. Examples are:
As a size constituent of finish for glass fiber/glass fabric composites
As an additive to phenolic, furan and melamine resins for foundry resins and abrasives
As an additive for sealants and adhesives
As an additive and/or primer for paints and varnishes to improve adhesion to the substrate
Important product effects that can be achieved through the use of KH-594 are:
Improved mechanical properties: E. G. Flexural strength, tensile strength, impact strength, modulus of elasticity
Improved resistance to moisture and corrosion
Higher temperature of deflection under load
KH-594 also helps improve processing properties such as
Increased filler content
