Micro Tuff™

Description FDA Approval Benefits of Micro Tuff™

Lubricity & Release Coefficient Of Friction

 

Erie Hard Chrome is an Approved Applicator of Micro Tuff™

 

Description Micro Tuff™ is a long-chain, highly cross-linked polymer, with an organic penetrating agent that is sold in bar form. It is used to impregnate metallic substrates and coatings, thereby, improving surface performance. Micro Tuff™ polymerizes during application, wherein it takes on synergistic properties.   Micro Tuff™ is impregnated into the micro-crystal structure of the metal. This provides a homogeneous and dense alloy of bonded polymer. Micro Tuff™ impregnation completely seals off the substrate and imparts time release lubricity to the overall surface.

Micro Tuff is easy and inexpensive to apply; special equipment is not required.

• Apply In-House And Eliminate Outsourcing
• Reduces Friction
• Improves Release
• Increases Lubricity
• Reduces Wear
• Eliminates Galling
• Less Corrosion
• Improves Product Quality

Once applied, the Micro Tuff™ impregnated surface will:

• Not change the dimensions
• Maintain the same surface color
• Be resistant to all solvents
• Resist heat to over 1,200°F

FDA Approval

All of the ingredients in Micro Tuff™ are on the FDA approved List Of "Indirect" Additives Used In Contact Substances for use with foods, food additives, medical devices and drugs. Using Micro Tuff™ Polymer on molds, tooling, dies and related manufacturing components qualifies as indirect usage. Click here for a copy of this list from the FDA website. (Top of Page)

Benefits of Micro Tuff™

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.

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
