Rockhard is the name of a range of coatings that is still being developed after 40 years. This family of protective coatings is particularly effective on magnesium and aluminum alloys. It is also used on steel, titanium and other metals. Rockhard coatings are highly resistant to weathering and a wide range of chemicals up to 450°F. Ideal for curing microporosity in magnesium, they also are resistant to re-chromating and re-anodizing.

New uses and markets are still being found for these incredibly versatile chemical and erosion resistant products. Here are some product applications that utilize Rockhard coatings:

• Helicopter Skins • Aircraft Undercarriages • Components for Space Capsules
• Guided Missiles • Computers • Torpedo Tubes • Jet Engine Interiors
• Fuel Pump Diaphragms • Heat Exchangers (allowing Aluminum to replace copper)
• Flexible Fuel Tanks • Collapsible Tube Interiors • Car and Truck Engines
