Selecting the right rust preventative for a specific product application is easy referencing Birchwood Casey’s handy corrosion resistance comparison chart.

Manufacturers can quickly choose from twelve different aqueous and solvent-based inhibitors and sealants to prevent rust and corrosion on all metal surfaces. The chart aids in selecting the proper Birchwood Casey rust preventative and corrosion inhibiting products according to needs for protection, lubricity, dryness and decorative appeal.

The different product formulations allow for variables such as the type of metal surface in question, level of protection needed, and conditions of exposure in handling, shipping and storage. Special considerations such as removability and post-treatment operations should be considered in the selection of the correct product.

8 solvent-based and 4 water-based products
The eight solvent-based products provide robust protection for various metal surfaces, including raw steel/casting inventory, in-process parts, finished products in distributor warehouses, or parts in long-term storage or overseas shipment. Rust inhibitors are graded based on their performance in ASTM B117 Salt Spray Testing and/or ASTM D1748 Humidity Testing. Depending on the rust inhibitor selected, the user can achieve protective coatings with either a slightly oily water-displacing film, or a dry-to-touch, non-oily sealant, or a soft-waxy, self-healing film. Two of the products are also available in high flash point, low-VOC versions for areas with sensitive air quality requirements.
Four Water-Based Products Offer Up To 48 Hours Salt Spray Protection

Following similar ASTM grading, Birchwood Casey’s four water-based products provide a wide range of protection levels and surface appearance. These products include a water-dilutable oil, a satin-gloss acrylic wax, a high-gloss urethane polymer sealant, and a high-gloss acrylic polymer emulsion.  These aqueous products have minimal VOC content and no flash point.

Widely used on tooling, motion control components, automotive parts, and in many other applications, all twelve Birchwood Casey products are available in 5 gallon and 55 gallon quantities and may be ordered online.
