    摘要: An aqueous alkaline paint stripper composition which forms a foam when dispersed from an aerosol container comprising:A. from 47 to 94% by weight of an aqueous solution containing from about 5 to about 40% by weight of at least one strongly alkaline substance,B. from 1 to 8% by weight of at least one surfactant,C. from 5 to 30% by weight of at least one propellant,D. from 0 to 5% by weight of at least one foam stabilizer and/or thickener, andE. from 0 to 10% by weight of at least one water-miscible organic solvent,and a method of stripping paint using the above paint stripper composition.

    摘要: Polyurethane prepolymers containing terminal isocyanate groups in which oleochemical polyols are present as the polyol component. The oleochemical polyols are ring opened products or partial ring-opened products of epoxidized fatty acid triglycerides with alcohols. The use of oleochemical polyols having a residual epoxide number of from 1.0 to 4.0% by weight of epoxide oxygen is preferred. The polyurethane prepolymers are particularly suitable for use in one-component or two-component polyurethane foam formulations.
