DEMCO POLYUREA /PURE

Descriptions

DEMCO POLYUREA / PURE; is a two-component, plasticizer-free, pure polyurean system consisting of 100% solid materials. It is applied by hot spraying technique at high pressure using application machines designed for two-component products. It has high chemical and mechanical resistance, high elasticity and strength, very good adhesion on concrete, metal and mineral surfaces. It dries quickly, its service time is short. Provides high crack bridging and covering. It reacts very quickly and dries quickly. It is applied easily and quickly. It does not form gava bubbles on properly prepared and primed floors. It is an environmentally friendly product.
