Paint stripper formulations in an effort to reduce the health, safety and toxicity concerns related to methylene chloride and methanol, while maintaining similar performance.

About

Background

Paint strippers have wide commercial application due to the relative ease of use when compared to various physical paint removal methods (scraping/sanding). Many of these paint removers are solvent based, utilizing methylene chloride, toluene, and methanol. While these solvents yield significant paint removal, they may also present potential health, safety and environmental concerns to both the user and the surrounding environment. These solvents are listed as Hazardous Air Pollutants by the U.S. EPA.  Alternative paint strippers which contain ingredients such as benzyl alcohol, dibasic esters, and N-Methyl-pyrrolidone (NMP) lack in comparative performance results. Hence, there is a need to have a paint stripper with safer chemicals and the companies are looking to eliminate hazardous components.

Technology

Inventors at UMass Lowell - Toxic Use Reduction Institute (TURI) have developed a set of paint stripper formulations in an effort to reduce the health, safety and toxicity concerns related to methylene chloride, toluene, and methanol, while maintaining similar performance. The alternative solvent blend contains no Hazardous Air Pollutants and is equally effective as compared to current formulations. 

Advantages


Environmentally friendly formulation - Formulation involves no Hazardous Air Pollutants
Safer than the effective hazardous solvents and works similar to these same solvents
Doesn’t stain wood or raise the wood grain
Comprised of chemicals that have small molecular volumes - Solvent blend can penetrate the various polymer coatings and attack the adhesive bond to the substrate
Cost-comparative
