3-Ureidopropyltriethoxysilane 50% solution in Methanol.
Synonym: N-(Triethoxysilylpropyl)urea 50% solution in Methanol
Countertype of DowCorning Z-6801

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.
