What is an MCU Coating? 

MCU stands for Moisture Cured Urethane and makes a very superior high performance  coating. These are a unique type of coating much better known in commercial industrial painting circles than within the general public market.  Most MCU coatings use tiny aluminum flake as pigment which gives them their classic silvery/gray color and enhances their remarkable properties.

MCU contain lots of solvents which aids in penetrating tiny cracks and crevices. The coating scavenges moisture from its contact surfaces and the air and undergoes an cross-linking molecular process which 'grips' or grabs onto surfaces for outstanding adhesion, even with poorly prepared surfaces. Removing internal surface moisture removes one of the key components necessary for rust development.

The resulting dry surface (aided by the stacking aluminum pigment platelets) provides a physical barrier to air and oxygen, another necessary component for rust to form.  The result is a thin, hard coating that seals our air, water, salts, minerals etc.  essentially encapsulating the surface  It therefore is one of the best, easy to apply, rust and corrosion control coatings.

Its amazing adhesion results in a versatile coating well suited for use on steel, aluminum, concrete, fiberglass, wood etc. It can be used as a primer/sealer, a middle coat or a exposed as a topcoat. The aluminum pigmented versions have no UV issues, can be applied at low temperatures and operate at temperatures of up to about 400 degrees F. Besides being used as a rust stopper is also has applications on  boats, roofing and flooring applications. In is used a lot in the industrial, automotive, marine and farm marketplaces. The AUTO RESTORATION market is one place these coatings are widely promoted within the 'DIY home' marketplace.
