MetaLube, Inc

Protect your finished product with high performance conversion coating technologies

Our customers rely on production tested conversion coating technologies to improve paint coverage, enhance paint adhesion, and maximize durability of the finished coating.  MetaLube offers a variety of conversion coating products that deliver these critical functions so you can focus on your finished product.

Our line of conversion coating products includes iron phosphates, zirconium based conversion coatings, and chrome free seal rinses.  These products are carefully formulated to meet the unique process and performance requirements of your paint line.

Process details to consider are numerous and some are line configuration, substrate type(s), application temperature, contact time, overflow rates, and the potential for line stops.  Performance requirements vary between customers, but common tests include adhesion, durability, and accelerated corrosion testing.
