VANABIO® AM2122
VANABIO® AM2122

Aminoethylaminopropylmethyldimethoxysilane

VANABIO®AM2122 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. 


VANABIO®AM2122 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.

Solubility: VANABIO® AM2122 is easily soluble in water with spontaneous hydrolysis occurring.


Caution: Due to solution enthalpies mixing water is exothermic. Always stir VANABIO® AM2122 into water. With alcohols miscibility is, in general, possible with self-catalyzed exchange of the alkoxy-groups. In aliphatic and aromatic hydrocarbons and (moisture-free!) ethers or esters VANABIO® AM2122 is easily soluble at differing levels. With ketones and various halogenated compounds a slow reaction can occur. Towards acids, epoxides or isocyanates VANABIO® AM2122 shows typical amine function. Some nonferrous metals can discolor upon contact.


Application


  • VANABIO® AM2122 can be used as adhesion promoters in polysulfide, polyvinyl chloride plastisol, silicone two-part urethanes and epoxy adhesives and sealants.


  • VANABIO® AM2122 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


  • VANABIO® AM2122 can be used to maintain the shelf life of the resin over long periods.


  • In terms of silane siloxane chemistry, VANABIO® AM2122 can be used as starting material in the synthesis of amino-functional silicones.


  • VANABIO® AM2122 can be used as additives to latex coatings, adhesives and sealants.


  • VANABIO® AM2122 can be used as adhesion promoters in one-part silylated urethane adhesives and sealants.


Packing and Storage


  • VANABIO® AM2122 is supplied in 200Kg steel drum or 950Kg IBC container.


  • In the unopened original container VANABIO® AM2122 has a shelf life of one year in a dry and cool place.
