摘要：
A room temperature curable anticorrosion sol-gel coating composition for a metal substrate, comprising a carboxylic acid or 2,4- pentanedione stabilized water based sol-gel of zirconate-silica nano particles which is combined with a glycidoxyalkyl-alkyoxysilane before coating onto a metal substrate. The coating is chemically cured on the metal substrate, forming a corrosion protective layer.
