Additive Package for In-Situ Phosphatizing Paint, Paint and Method

Abstract
This additive package for in-situ phosphatizing paint provides independent, but simultaneous reactions to metal surfaces and to polymer paint film. The in-situ phosphate layer forms covalent bonds with paint films providing strong coating adhesion, thus offering excellent corrosion protection.

Potential commercial uses and users:
Green and environmentally friendly and chrome-free metal finishing for Original Equipment Manufacturers (OEM), fastener, and aerospace industries.

Advantages:
The combination of the phosphate, primer and topcoat applications into a single-step process provides superior surface protection while eliminating the expensive and inefficient phosphatizing line. The unicoat phosphate/paint system is environmentally friendly since it eliminates the toxic sludge produced during the traditional multi-step coating process. Use in solvent-based paints allows for reduction of volatile organic compounds in the formulation.
