YAC-A212 is a colorless, strongly alkaline liquid with amine smell being very sensitive to hydrolysis. It is a diamino-functional silane capable of providing good adhesion and superior elougation and flexibility at the polymer-substrate interface.
YAC-A212 amino silane is used to promote adhesion between glass, mineral and metal surfaces - reinforcements, fillers and substrates - and resins that react with amino groups in systems such as PVC plastisol, polyurethane, or epoxy-based adhesives and sealant, or in phenolic and epoxy molding compounds. Its reduced alkoxy functionality might also be useful in waterborne systems such as latex coatings, adhesives and sealants, providing lower reactivity and therefore higher stability in the aqueous environment.
It is the equivalent of Momentive's A-2120, Dow's Z-6023, Wacker's GF95, Evonik's Dynasylan 1411, ShinEtsu's KBM-602 silane.
YAC-A212 can be used as adhesion promoters in polysulfide, polyvinyl chloride plastisol, silicone two-part urethanes and epoxy adhesives and sealants.
YAC-A212 can be used as silicone additives for cold-curing phenolic and furan foundry resins to improve the flexural strength of the sand-resin composites while
YAC-A212 can be used to maintain the shelf life of the resin over long periods.
In terms of silane siloxane chemistry, YAC-A212 can be used as starting material in the synthesis of amino-functional silicones.
YAC-A212 can be used as additives to latex coatings, adhesives and sealants.
YAC-A212 can be used as adhesion promoters in one-part silylated urethane adhesives and sealants.
YAC-A212 is supplied in 200Kg steel drum or 950Kg IBC container.
In the unopened original container YAC-A212 has a shelf life of one year in a dry and cool place.
