What Does Polyurethane Coating Mean?
A polyurethane coating is a polyurethane layer applied to the surface of a substrate for the purpose of protecting it. These coatings help protect substrates from corrosion, abrasion and other deteriorating processes. While polyurethane coatings are relatively durable, this durability also makes them more resistant to abrasion and less prone to dents and scratches.
Demech Chemical Products Pvt. Ltd polyurethane coatings are organic coatings made from polyol compounds. Due to their low permeability and good chemical resistance, 100% solid polyurethane coatings act as a barrier coating by blocking migration of moisture, oxygen and other chemicals to the substrate. They have high electrical resistance to effectively block formation of the corrosion cell on steel and concrete surfaces.
Demech chemical high built 100 solid elastomeric polyurethane coating products are manufactured as per national and international standards. These environmentally friendly products are resilient, flexible and tough in nature and demonstrate excellent impact resistance and crack bridging ability.
