Callington CH3003 is a non-evaporative, acid-activated paint and primer remover for removal of 2-pack polyurethane and epoxy paint systems. CH3003 is designed for use where phenolic & chlorinated strippers are not desired. It’s a high flash point, low vapour pressure and absence of chlorinated compounds like Methylene Chloride makes it user-friendly.

Directions for Use

Optimum results can be achieved when the application temperature is above 18 ºC. Spray or brush CH-3003 onto surface to be stripped. Dwell time varies with temperatures and airflow, but should be from 1 to 3 hours, with a maximum of 24 hours. Once the stripper has loosened the paint, the surface should be squeegeed to remove the loosened paint, and stripper residues. If a second spraying of CH-3003 is required, it should be applied after the loosened paint has been removed.

Once the operation is complete, it is necessary to clean the surface with an alkaline detergent. Callington CH511C is recommended. This removes stripper residues and neutralises any remaining acid. The surface must be cleaned with an alkaline cleaner such as CH511C within one hour after the stripper has been removed. Test the pH of the surface with litmus or pH paper to ensure that it is neutral above 7.0. If not, re-application of the alkaline solution will be required.
