Royal Purple's Maxfilm is a multi-purpose, synthetic lubricant that deeply penetrates, cleans and loosens parts. Once applied, it evaporates and leaves a “tenacious lubricating film” for improved operation and long-lasting protection against wear, rust and corrosion. In addition to its lubricating qualities, it is recommended for loosening stuck parts, preserving and protecting parts in storage against rust and corrosion, and acting as a manual cutting fluid for easier hand drilling, tapping, metal cutting, etc., of both steel and aluminum. Maxfilm has been engineered to be environmentally friendly and its solvent biodegrades to leave only small quantities of calcium carbonate and calcium sulfate, both of which are naturally occurring minerals.
