Water-based metallic base composition based on acrylic latex resins using a water-soluble resin as a medium for aluminium and hectorite clay for Rheology regulation

摘要

The present invention is concerned with a water borne coating composition designed for the coating of transportation vehicles. The invention is related to coating compositions primarily for a basecoat of a multi-coat system which includes primers and transparent clear coats, particularly with base coats containing metallic pigments, based on acrylic latex polymers. The base coat composition consists of pigmented base containing an acrylic latex resin, reducer base containing a rheology control agent and optionally in addition an aluminium pigment base containing a water reducible resin and a neutralization base containing a water reducible resin.
