VANABIO® AM2120
VANABIO® AM2120

Aminoethylaminopropyltrimethoxysilane

VANABIO® AM2120 is a clear, colorless, strongly alkaline liquid with smell being very sensitive to hydrolysis.


VANABIO® AM2120 amino silane is used as adhesion promoter at organic/inorganic interfaces, for modification of surfaces (corrosion prevention, component of primers) or silicone- polymers or as crosslinker (moisture crosslinking of polymers). The application as "coupling agent" leads in general to an improvement of mechanical and electrical product properties above all under exposure to heat and/or moisture.


VANABIO® AM2120 is the equivalent of Momentive's A-1120, Dow's Z-6020, Wacker's GF91, Evonik's Dynasylan DAMO, ShinEtsu's KBM-603 silane.

Solubility: VANABIO® AM2120 is unlimited miscible with water with spontaneous hydrolysis occurring.


Caution: Due to solution enthalpies mixing water is exothermic. Always stir VANABIO® AM2120 aminoethyl aminopropyl trimethoxysilane 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® AM2120 aminoethyl aminopropyl trimethoxysilane is easily soluble at differing levels. With ketones and various halogenated compounds a slow reaction can occur. Towards acids, epoxides or isocyanates DAMO silane CAS 1760 24 3 shows typical amine function. Some nonferrous metals can discolor upon contact.


Application


  • VANABIO® AM2120 may be used as an effective coupling agent for clay reinforced elastomers such as natural and nitrile rubber, to improve physical and dynamic properties.


  • VANABIO® AM2120 silane coupling agent may be used as an effective coupling agent for mineral reinforced nylon 6, nylon 6/6 and polybutyleneterephthalate, to increase the flexural and tensile strength of the thermoplastic composite.


  • VANABIO® AM2120 may be used as a fiberglass finish or a resinous additive for fiberglass reinforced phenolic, melamine and expoxy thermoset composites.


  • VANABIO® AM2120 may be used as a mineral binders in in foundry and abrasive composite applications, to improve adhesion, increase composite strength.


  • VANABIO® AM2120 may be used as an adhesion promoters in polysulfide, polyvinyl chloride plastisol, silicone two part urethane and epoxy silane adhesives and sealants.


  • VANABIO® AM2120 may be used as a glass and metal primer, to improve the adhesion of many coatings (urethanes, epoxies, phenolics and others) to glass and metal surfaces.

Packing and Storage


  • VANABIO® AM2120 is supplied in 200Kg steel drum or 1000Kg IBC container.


  • In the unopened original container VANABIO® AM2120 has a shelf life of one year in a dry and cool place.
