SCA-U60E 3-Ureidopropyltriethoxy-Silane (CAS No. 23779-32-0) CAS NO.23779-32-0

3-Ureidopropyltriethoxysilane (CAS No. 23779-32-0), Silane coupling agent SCA-U60E, is a bifunctional organosilane possessing a reactive organic ureido group and a hydrolyzable inorganic triethoxysilyl group. The dual nature of its reactivity allows SCA-U60E 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. SCA-U60E 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.

3-Ureidopropyltriethoxysilane (CAS No. 23779-32-0), Silane coupling agent SCA-U60E, 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 SCA-U60E 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

SCA-U60E also helps improve processing properties such as increased filler content

 

Abstract
3-Ureidopropyltriethoxysilane (CAS No. 23779-32-0), Silane coupling agent SCA-U60E, is a bifunctionalganosilane possessing a reactiveganic ureido group a hydrolyzable inorganic triethoxysilyl group. The dual nature of its reactivity allows SCA-U60E to bind chemically to both inorganic materials (e. G. Glass, metals, fillers)ganic polymers (e. G. Thermosets, thermoplastics, elastomers), thus functioning as an adhesion promoter as a surface modifier. SCA-U60E is a 50% solution of silane in methanol, is a colorless liquid with an alcohol-like odis soluble in alcohols, ketones, esters aromatic hydrocarbons.
