Additive for coating compositions, e.g. paints, sizes, varnishes and lacquers, comprises a nonionic and/or cationic surfactant, metasilicate, gluconate, glycol and water

摘要

Additive for coating compositions comprises (wt.%): nonionic and/or cationic surfactant (0.5-30), alkali metal metasilicate (0.01-4), alkali metal gluconate (2-10), glycol (0.01-4) and water (to 100). An independent claim is also included for a coating composition containing 0.01-3 wt.% of the additive.
