Cellular plastic from disposable pressurized aerosol cans

摘要

A composition useful for the production of foam plastics from disposable pressurized containers is provided. The composition comprises at least one polyisocyanate or isocyanate prepolymer, at least one catalyst for the reaction of the isocyanate group with the OH group, at least one blowing agent and at least one foam stabilizer. One day at the latest after application from said disposable pressurized container, the residue of said composition left in the pressurized container has a diisocyanate monomer content of less than 5.0% by weight, based on the residual contents of the emptied container.
