Witcol Rustcol RP-1204 and Witcol Rustcol RP-3204 are barium-free corrosion preventives that offer cold-rolled steel excellent protection in condensation, salt spray, and open shed conditions. Witcol Rustcol RP-1204 and Witcol Rustcol RP-3204 have good drawing properties and are also easily removed with neutral or alkaline water-based cleaners. They are thixotropic and provide optimum film stability on vertical surfaces. They protect semi-finished cold-rolled steel components during transportation and shed storage when good protection and easy removability are priorities.

Witcol Rustcol RP-1204 and Witcol Rustcol RP- 3204 can be applied by dipping, spraying, or rolling. Those are normally applied electrostatically to cold-rolled steel. When electrostatically spraying or filtering, the temperature should not fall below 40°C. As with all thyrotrophic products, light settling can occur after longer periods of storage. If sealed in the original container, Witcol Rustcol RP-1204 and Witcol Rustcol RP-3204 can be stirred for at least 3 years at 5-40° C.
