HMF Microfinish Coating Has Many Benefits

Mirror-Smooth Microfinish Coating Features Very Low COF and Eliminates Static Buildup

• Prevents scratching of films and foils
• Excellent corrosion and moisture resistance
• Temperature range from -250°F (-157°C) up to 950°F (510°C)
• Electrically conductive
• Excellent heat transfer
• None of the peeling, chipping, and cracking problems of chrome
• Meets FDA, USDA, NSF and AgriCanada codes for food and drug contact
• Reflective chrome-like appearance
• Excellent bond to parent metal
• Environmentally acceptable
• Increased hardness - can't cut it with a knife
• Less friction generation - low COF without polymers
• Permanent lubricity
• Maximum abrasion resistance
• Provides mold release
• For most base metals

MAGNAPLATE HMF is a proprietary, multi-step coating process that creates an extremely hard (up to an equivalent of Rc 68), mirror-smooth (down to 4RMS), highly-reflective microfinish on the surface of ferrous metal, copper or aluminum alloy components. MAGNAPLATE HMF is capable of reaching a microfinish of 8 microinches or less. Since one of the most important variables in friction measurement is microfinish, these two properties are interrelated. In many cases, a lower microfinish will result in a lower COF. A low COF through a low microfinish is the primary objective of MAGNAPLATE HMF.

Coefficient of friction: as low as 0.03 against burnished HI-T-LUBE®. Eliminates "stick-slip" and undesirable vibration of higher breakaway friction. Effectively ensures against galling and seizing. Eliminates generation of Lanier lines or similar stress lines in sensitive plastic film processing.

The likelihood of galling or seizing is virtually eliminated. Equilibrium Wear Rates from Taber abrasion testing using a CS10 wheel indicates an extraordinarily low weight loss of 0.2 - 0.4 mg per 1000 cycles. This is far less than that of any conventional surface treatment or many other high technology protective coatings.

The suggested useful operating range is up to 650°F (343°C).

Salt spray per ASTM B-117, exceeds 336 hours when thickness of coating is 0.001" or greater. MAGNAPLATE HMF provides a level of chloride protection that is vastly superior to that of chrome plating.
