GENIOSIL VTME is a clear, colorless liquid with a characteristically aromatic odor. The use of GENIOSIL VTME in mineral-filled polymers (e.g. polymers filled with kaolin, ATH or magnesium hydroxide) leads to a marked improvement in the mechanical and electrical properties, and to increased moisture resistance in particular. In addition, it renders the particles extremely water-repellent, which results in improved dispersibility, reduced melt viscosity and thus improved processability. Use of GENIOSIL VTME as a co-monomer in polymers results in binders which, thanks to crosslinking and strong adhesion to the substrate, exhibit much improved wet scrub resistance and abrasion resistance. Organic surface coatings will adhere more strongly to inorganic substrates, such as glass or metals, that have been treated with GENIOSIL VTME. As a result, these coatings demonstrate markedly greater scratch resistance and resistance to chemicals.
