3-Ureidopropyltriethoxysilane 50% solution in Methanol.
Synonym: N-(Triethoxysilylpropyl)urea 50% solution in Methanol
Countertype of DowCorning Z-6801
Chemical Structure
Introduction
SiSiB® PC2520 is a bifunctional organosilane having a reactive organic ureido group and a hydrolyzable inorganic triethoxysilyl group. The dual nature of its reactivity allows SiSiB® PC2520 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.
SiSiB® PC2520 is a 100% 3-Uriedopropyltriethoxysilane. SiSiB® PC2521 is a 50% solution of silane in methanol.

Applications
SiSiB® PC2520 can be used with such polymers as epoxy, phenolic, furan and melamine resins, polyurethanes, PA, PBT, PE, EVA, PP, PVB, PVAC, acrylics and silicones.
SiSiB® PC2520 can be used as a size constituent of finish for glass fiber/glass fabric composites
SiSiB® PC2520 can be used as an additive to phenolic, furan and melamine resins for foundry resins and abrasives.
SiSiB® PC2520 can be used as an additive for sealants and adhesives.
SiSiB® PC2520 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 PC2521 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.
