Abstract
*-Ureidopropyltriethoxysilane (CAS No. *********0), Silane
coupling agent KH***4, is a bifunctional organosilane possessing
a reactive organic ureido group and a hydrolyzable inorganic
triethoxysilyl group. The dual nature of its reactivity allows
KH***4 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***4 is a *0% solution of
silane in methanol, is a colorless liquid with an alcohol-like
odor and is soluble in alcohols, ketones, esters or aromatic
hydrocarbons.

Applications
*-Ureidopropyltriethoxysilane (CAS No. *********0), Silane
coupling agent KH***4, 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***4 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***4 also helps improve processing properties such as
Increased filler content
Reminder
Purity *-Ureidopropyltriethoxysilane without solvents is
available on your requets.
