Abrasion resistant coatings comprising silicon dioxide dispersions.

摘要

Transparent abrasion resistant coatings capable of withstanding 1000 hours of accelerated weathering are comprised of colloidal silicon dioxide particles dispersed in ethylenically unsaturated aliphatic and/or cycloaliphatic monomers that are substituted by a protic group. The coatings are useful in protecting plastic, wood, metal and ceramic surfaces.
