PROCESS FOR OBTAINING A TRANSPARENT COATING ON PANES OF NORMAL SAFETY GLASS

摘要

There is provided an improved curved automotive windshield having been coated with a polymeric layer. The coating is prepared by centrifugally coating a polymerizable solution on a glass substrate and curing the layer to form interpenetrating polymeric network comprising an aliphatic polyurethane and an acrylic polymer, wherein the polymer is physically interpenetrated with but is not cross-linked to the aliphatic polyurethane on the glass substrate. The coated windshield exhibits excellent optical properties.
