PU Flooring
Generally speaking, 100% Solids Polyurethane Coating are an organic coating made from the cross linking reaction of Isocyanate and Polyol compounds. The two compounds chemically react to form a Polyurethane Coating. There is no by-product, other than heat from the reaction between isocyanates and polyols.
R-N=C=O + R’-OH –> R-NH-CO-O-R’ + Heat
Isocyanate Polyol Polyurethane
100% Solids Polyurethane Coating can be applied at high film thicknesses (500-3000 Microns) with minimal sagging, in a single coat. They cure rapidly even at sub zero temperatures due to the exothermic reaction between the Isocyanate and the Polyol.Due to their low permeability and high chemical resistance, 100% Solids Polyurethane Coatings act as a ‘barrier coating’ by blocking out moisture, oxygen and other chemicals from the surface. They have high electrical resistance to effectively block the corrosion cell on steel surfaces.
Polyurethane clear coat can be applied over epoxy flooring. Polyurethane floor coating will help protect the epoxy from yellowing and it will provide for a longer wearing and more scratch resistant surface. It gives maximum combined benefit out of both materials.
List of Polyurethane Applications
Polyurethane flooring is mostly preferred in food industries like dairy, milk, cold storage etc. that have exposure to organic acids, lactic acids. PU Flooring has better thermal resistance properties and flexibility. Hence it is a preferred choice for heavy foot traffic, area requires higher mechanical, chemical & temperature resistance if budget in not a constraint.
Application Areas for PU Flooring
- Food Industries , Cold Storage etc.
- Heavy Engineering & Metal Processing Industry.
- Warehouses and heavy duty storage area.
- Car Parking.
-
Heat Resistance area up to certain extent.
