Micro Tuff™ impregnation improves the surface characteristics of metallic surfaces by increasing Lubricity and reducing both Friction and Corrosion. The Wear Life of components is, thusly, increased by a significant amount.

Micro Tuff™ was originally developed for chrome plating and has later been expanded to seal virtually any metallic surface. Micro Tuff™ can be used to improve the following surfaces: tool steel, low alloy steel, stainless steel, thermal spray, aluminum, copper, hard chrome, nickel, electroless nickel and a host of others. Followings are photomicrographs of Micro Tuff™ impregnated into a chrome plated tool steel surface.

Filling the chrome crack structure with Micro Tuff™ significantly increases the corrosion resistance and a use life of Tooling, Dies, Molds, Rolls, Screws, Rods and Hydraulics.

The increased release and greater lubricity makes tooling last longer and gives better performance. Reduced sticking, plate-out, plastic build up and burning results in lower maintenance costs and greater up-time for additional production. Mold cleaners and releases can still be used and Micro Tuff™ can easily be re-applied to tooling in production while it is still hot for even longer surface life. 

Lubricity & Release
The Micro Tuff™ surface is considerably smoother and has a much lower coefficient of friction. The increase in lubricity provides a unique "non stick" characteristic with greatly increased release properties. Following are typical static Coefficient Of Friction Values:

Coefficient Of Friction Static
Steel on Steel: 0.60
Micro Tuff™ on steel: 0.18
Conventional chrome on steel: 0.16
Micro Tuff™ on Chrome on steel: 0.04

Reduced Porosity
Micro Tuff™ fills microscopic porosity in metals and plated coatings. The impregnation into the crystal structure completely seals the substrate. This sealing allows the surface to perform much better.

Adhesion of plated coatings is improved by eliminating the corrosive effect of ions which can undermine the deposit causing a separation of the coating.

Corrosion Resistance
The increase in corrosion resistance is significant as corrosive salts like chlorides cannot penetrate the dense micro structure of the bonded polymers. Independent corrosion tests indicate a typical 65x increase using the Cass Test and a 106x increase using the 5% Salt Spray Test.

Wear Resistance
Testing under “real world” conditions indicates that Micro Tuff™ provides a typical increase in wear resistance of between 4 – 10x when compared to untreated surfaces. Part life is increased up to 10 times and corrosion protection of up to 1,000 hours of ASTM B-117 Salt Spray is reported.

The use of Micro Tuff™ increases performance and gives you the competitive edge.
