Heatbath Corp. has expanded its line of rust preventative products with the introduction of Durawax, a multi-purpose synthetic wax emulsion that is designed to provide excellent coverage over bare steel or conversion coatings such as black oxide and phosphates. The silicone-free product forms a hard, shiny dry film that reportedly enhances surface appearance and durability.

Heatbath Corp. has expanded its line of rust preventative products with the introduction of Durawax, a multi-purpose synthetic wax emulsion that is designed to provide excellent coverage over bare steel or conversion coatings such as black oxide and phosphates.

The silicone-free product forms a hard, shiny dry film that reportedly enhances surface appearance and durability. Applied over black oxide at 50% by volume, it delivers more than 400 hours of corrosion protection when subject to 100% relative humidity (ASTM D2247.) It can also be used as a dry film lubricant for torque reduction and other purposes, and can be used as an emulsion for the weatherproofing of military implements.

The product is nonflammable, is used at ambient temperature, and dilutes with tap water up to 50% by volume. According to the company, the bath is stable and easy to replenish. Parts should be free of oils and residues, but predrying parts before processing is not required. Application is by spray, or immersion for 1-3 minutes. Films air-dry quickly, but forced air or spin drying can be used for in-process and other applications requiring faster cure. If needed, the film can be removed with a hot alkaline cleaner.
