3-Isocyanatopropyltriethoxysilane Description
CFS-885, 3-Isocyanatopropyltriethoxysilane is a primary isocyanate functional
silane with high functionalities. It combines the functionality of an
isocyanate group and a triethoxy group. A reactive silanol group will be formed
after hydrolysis with the presence of alkoxy groups. Owing to the triethoxy
group, Co-Formula isocyanate silanes provide excellent adhesion to a variety of
inorganic substrates, like metals and glass. Compared to other isocyanate
silanes, CFS-885 can hydrolyze slowly and compositions will get high stability.

CFS-885, 3-Isocyanatopropyltriethoxysilane can react with active hydrogen in
organic polymers easily. CFS-885 with high functionality can be used as the
equivalent of Momentive Silquest A-Link 25 or ShinEtsu KBM-9007.
3-Isocyanatopropyltriethoxysilane Application
CFS-885 can be used as a crosslinker and an adhesion promoter of RTV and
enhance the bonding between organic rubber and inorganic substrates.
CFS-885 can be used as an adhesion promoter and a coupling agent in paints and
silicone sealants manufacturing, especially suitable for one-component moisture
curable urethane system.
CFS-885 can be used to improve chemical and physical performance of composite
materials, acting as a surface modifier and a crosslinker of organic materials
and inorganic substrates.
CFS-885 can be applied for resin or polymers modification in silyl modified
urethane polymers (known as SPUR polymers) and silquest silane terminated
polymers (MS polymers).
3-Isocyanatopropyltriethoxysilane Packaging
CFS-885 is offered in 50L steel drums, 200L PVF steel drums and 1000L IBC
totes.
Please contact Co-Formula team if any special packaging request about CFS-885.
3-Isocyanatopropyltriethoxysilane Storage
CFS-885 should be stored in its original containers and used up as soon as
possible after opening.
CFS-885 should be stored in a cool, well-ventilated place, and avoid exposure
to humidity.
When stored in a strictly sealed and unopened container, CFS-885 has a shelf
life of 12months.
