VPS SIVO 1208 is a composition of primary amino silanes and lubricants with enhanced wetting behavior.
The dual nature of its reactivity allows VPS SIVO 1208 to bind chemically to both inorganic materials (e.g. glass, metals, fillers) and organic polymers (e.g. thermosets, thermoplastics, elastomers) thus functioning as an adhesion promoter, crosslinker, and/or surface modifier.

Benefits at a glance
Reactivity
In the presence of water, the ethoxy groups of VPS SIVO 1208 hydrolyze and form reactive silanol (Si-OH) groups which can bond to a variety of inorganic substrates. Upon hydrolysis ethanol is released. The organophilic amino group of VPS SIVO 1208 can react with a suitable polymer. The hydrolysis of VPS SIVO 1208 takes place autocatalytically.
Examples of suitable inorganic substrates are glass, glass fibers, glass wool, mineral wool, silicic acid, quartz, cristobalite, wollastonite, mica as well as aluminum trihydrate, magnesium dihydrate, kaolin, talc, other silicate fillers, metal oxides and metals.
VPS SIVO 1208 may be used with such polymers as epoxy, phenolic, furan and melamine resins, polyurethanes, PA, PBT, PC, EVA, modified PP, PVB, PVAC, PVC, PS, nitrile rubber, polyester, acrylates and silicones.
