Based on hybrid technology, Seal It Liquid Membrane has high elasticity, even under climatic weather variations. It does not harden under cold conditions and has very high stability to temperature variations (from 50 degrees C to +120 degrees C), to UV radiation and to external chemical attack. Excellent resistance to ageing, ultraviolet and discolouration. Under test conditions, Seal It Liquid Membrane has superb thermal properties and outperforms black bitumen by 36% at just 0.8mm thickness, it is also 11.3% more efficient than solar reflective paint which helps reduce energy costs.
