VANABIO® IS2272

3-Isocyanatopropyltriethoxysilane

VANABIO® IS2272 is an isocyanate functional silane. It is used for the functionalization of numerous compounds with active hydrogen atoms. 


VANABIO® IS2272 hydrolyzes in the presence of moisture to form silanols, which can react with themselves to produce siloxanes. It is the equivalent of Momentive's A-Link 25, Wacker's GF41, ShinEtsu's KBE-9007 silane.

Application


  • VANABIO® IS2271 and VANABIO® IS2272 can be used as silane crosslinking agent for one part moisture curable urethane adhesives, sealants and coatings.


  • VANABIO® IS2271 and VANABIO® IS2272 can be used as adhesion promoters for one part moisture curable and two part reactive urethane systems.


  • VANABIO® IS2272 hydrolyzes slower than VANABIO® IS2271. VANABIO® IS2272 is better for applications requring greater open time or enhanced shelf stability.


  • VANABIO® IS2271 and VANABIO® IS2272 can be used as adhesion promoters for silicone coatings or sealants, to enhance adhesion to organic substrates with active hydrogen atoms.


  • VANABIO® IS2271 and VANABIO® IS2272 can provide good wet adhesion to glass, metal and other inorganic substrates, and can provide good thermal, chemical and UV stable performance.

Packing and Storage


  • VANABIO® IS2272 is supplied in 20Kg plastic drum, 190Kg steel drum or 950Kg IBC container.


  • In the unopened container VANABIO® IS2272 has a shelf life of one year.
