Abstract

Soln. containing 0.5-4.0 wt. % aluminium tristearate and 0.005-0.1 wt. % magnesium oleate in a liquid chlorinated hydrocarbon, esp. trichloroethylene. The solution is used to prevent the sticking of cold foamed polyurethane foam castings to moulds containing metallic soap. Advantage is that even and complete ejection is possible and that the material is suitable for spraying on to the mould.
