Abstract
Paint sludge is mixed with a polyether or polyester polyol. Optionally, lignin in the range of 0.25 to 70% by weight may be mixed with polyol. The paint sludge-polyol mixture is mixed with an isocyanate for curing the material into a mass. Alternatively, the lignin-polyol-paint sludge mixture is mixed with an isocyanate for curing the material into a mass. The lignin improves the flame resistance and moisture resistance of the mass. A catalyst may be added to the mixture to improve the rate of reaction.
