Rust blocker has low VOC content
Dri Touch® Amber rust blocker from Birchwood Casey has a low VOC content, high flash point, and almost no odor.
Rated for 100 to 150 hours salt spray and more than 600 hours humidity protection, the rust blocker meets water displacement test Mil-C-16173 and stain test Mil-C-22235A. With a flash point of 248 degrees F, the product is suitable for use in manufacturing plants that are under air quality restrictions and in areas with flammability hazards. It delivers rust protection more than double that of other water-based products, according to the manufacturer.
The rust blocker can be used on packaged products such as hand tools without causing odor, air contamination, or fire safety problems. It also can be applied to raw materials such as bar steel and castings before cutting and machining. Suitable for use as a corrosion preventive over black oxide or phosphate conversion coatings, the product seals out corrosion and enhances depth of color, the company says. It also can be used on uncoated metal surfaces for long-term storage.
Its thin consistency allows the rust blocker to penetrate recessed areas and lift moisture from blind holes. It forms a protective barrier film that resists atmospheric humidity and corrosion.
