Rated for 96-120 hrs salt-spray and 600+ hrs humidity protection, Dri Touch Amber Low-VOC from Birchwood Technologies offers more than double the rust protection of other water-based products, the company says. The rust blocker meets Mil-C-16173 water displacement test and Mil-C-22235A stain test requirements. With a 248°F flash point, it is said to be well-suited for manufacturing plants that are under air quality restrictions and in areas with flammability hazards.
The rust blocker can be used on packaged products such as hand tools without causing odor, air contamination or fire safety problems. It can also be applied as a general purpose rust inhibitor to raw materials such as bar steel and castings prior to cutting and machining. When used over black oxide or phosphate conversion coatings, Dri Touch Amber Low-VOC is formulated to seal out corrosion and enhance depth of color. It can also be used on uncoated metal surfaces for long-term storage.
The pale, amber liquid produces a film thickness of 0.15 mil and provides coverage of approximately 1,500 sq. ft./gal. The liquid’s very thin consistency is designed to quickly penetrate recessed areas and lift moisture from blind holes. It also forms a protective barrier film that resists harmful atmospheric humidity and corrosion.
Dri Touch Amber Low-VOC can be applied to wet or dry surfaces by immersion or pump spray processes. The non-conductive film dries quickly and provides break-in lubricity where needed without interfering with proper operation, the company says. It also is compatible with most lubricants, hydraulic oil and cutting oil.
