Introduction
3-Ureidopropyltriethoxysilane is a bifunctional organosilane having a reactive organic ureido group and a hydrolyzable inorganic triethoxysilyl group. The dual nature of its reactivity allows 3-Ureidopropyltriethoxysilane to bind chemically to both inorganic materials (e.g. glass, metals, fillers) and organic polymers (e.g. thermosets, thermoplastics, elastomers), functioning as an adhesion promoter and as a surface modifier. 3-Ureidopropyltriethoxysilane is a 50% solution of silane in methanol; it is a colorless liquid with an alcohol-like odor and is soluble in alcohols, ketones, esters or aromatic hydrocarbons.
Applications:
- 3-Ureidopropyltriethoxysilane can be used with such polymers as epoxy, phenolic, furan and melamine resins, polyurethanes, PA, PBT, PE, EVA, PP, PVB, PVAC, acrylics and silicones.
- Used as a size constituent of finish for glass fiber/glass fabric composites.
- Used as an additive to phenolic, furan and melamine resins for foundry resins and abrasives.
- Used as an additive for sealants and adhesives.
- 3-Ureidopropyltriethoxysilane can be used as an additive and/or primer for paints and varnishes to improve adhesion to the substrate.
The most important effects which can be achieved using 3-Ureidopropyltriethoxysilane are improvements in product properties, such as:
- 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.
