THE COMPOSITION OF PROPRIETARY PAINT STRIPPERS
1. Martens (1974) rated the efficiency of chlorinated solvents with respect to the time required to wrinkle a standard oleoresinous film. In general, the efficiency of a chlorinated solvent decreases as the chlorination or the chain length of the organic radical increases. No further information is given about the experimental design. He arrived at the following rating:
2. Methanol is the most widely used co-solvent. If more than 4% methanol is used, the remover must be identified as poisonous on the container. Methanol, a low molecular weight polar solvent, has a strong activating effect and adds to the versatility of the remover (Kirk and Othmer 1985).
3. Amines, e.g., 2-(N,N-dimethylamino)ethanol, are not as corrosive as acids and prevent container corrosion by scavenging hydrochloric acid which is released by the decomposition of methylene chloride (Kirk and Othmer 1985). Amines may discolor wood or react with copper or cadmium surfaces (Martens 1974).
