Abstract

Light weight low strength bulk material e.g. expanded is reinforced with high strength plastic esp. in the form of an external cladding as internal or external framing or similar reinforcement. It is applied in liq. or semi-liq. form by dipping pouring painting, or spraying and is esp. polyol with isocyanate in ratio 1-4:1 with necessary catalysts prometers moderators, colourings etc. it also provides chemical resistance and the desired external appearance.
