Metallic water borne base coat composition based on acrylic latex resins using acrylic resins derived from vinyl monomers having nonionic and urethane functionality for aluminum storage and a treated hextorie clay for rheology control - water base 9

A method of forming a water-borne metallic base coat kit composition consisting essentially of mixing:

• A. An aluminum base consisting essentially of:
• 1. A water reducible solvent borne acrylic resin having nonionic, urethane and acid functionality consisting essentially of:
• (a) at least one monomer having acid functionality.
• (b) at least one monomer having urethane and nonionic functionality prepared by the reaction of:
• a capped polyether having a single active hydrogen functionality with a polyisocyanate compound to produce a partially capped isocyanate intermediate which is further reacted with a first ethylenically unsaturated compound having at least one active hydrogen group to produce a second ethylenically unsaturated compound having urethane and nonionic functionality.
• (c) And a third ethylenically unsaturated compound
• 2. an aluminum flake treated for water stability at a level of 4-30% by weight, G,45
• 3. 25-55% total solids by weight,
• 4. 35-50% total water miscible organic solvent by weight,
• 5. 5-35% total binder by weight.
• B. an aqueous pigmented base consisting essentially of an acrylic latex resin and,
• C. an aqueous reducer base consisting essentially of a pregelled sodium lithium magnesium silicate hectorite clay rheology control agent.
