SiSiB® PC2520

3-Ureidopropyltriethoxysilane

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 silane surface modifier. SiSiB® PC2520 is a 100% 3-Uriedopropyltriethoxysilane. It is a 50% solution of silane in methanol.

Application


  • 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 silicone 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 silicone 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.


Packing and Storage


  • SiSiB® PC2520 is usually supplied in 50% methanol solution. SiSiB® PC2521 is supplied in 180Kg steel drum.


  • In the unopened original container SiSiB® PC2520 has a shelf life of one year in a dry and cool place.
