Abstract
Methylene chloride-free coating remover compositions are disclosed that contain N-methyl-2-pyrrolidone and one or more plant or animal-derived oils. The compositions optionally contain a miscibilizing solvent, thickener, and surfactant. Effective, economical, low-toxicity, low-volatility coating removers that are largely biodegradable and are derived from renewable resources are provided.
