SCA-U60M 3-Ureidopropyltrimethoxysilane (CAS No:23843-64-3) CAS NO.23843-64-3

3-Ureidopropyltrimethoxysilane (CAS No. 23843-64-3), silane coupling agent SCA-U60M, is a bifunctional organo-silane possessing a reactive organic ureido group and a hydrolysable inorganic trimethoxysilyl group. The dual nature of its reactivity allows SCA-U60M 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-U60M is amber, transparent and viscous liquid with an alcohol-like odor and soluble in alcohols, ketones, esters or aromatic hydrocarbons.

Applications and Performance

3-Ureidopropyltrimethoxysilane (CAS No. 23843-64-3), silane coupling agent SCA-U60M, 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-U60M 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-U60M also helps improve processing properties such as increased filler content. Compare to its ethoxy counterpart, SCA-U60E, SCA-U60M has a faster reaction speed which is sometime very important in quick-drying sealant and coating application.
