Polyurethane coatings are a well established family of coatings with proven properties.
There are thousands of different polyurethane formulations, polyurethanes can contain solvents, can be solvent free, water based, single or dual components, applied cold or hot.
A polyurethane coating (PU paint) is a hard-wearing, highly-resistant coating used in industrial and architectural coating systems for steelwork, concrete, wood, and other substrates.
Polyurethanes have good UV resistance i.e. do not fade in sunlight like epoxies and are flexible when cured.
Polyurethanes are a combination of a polyol resin and an isocyanate hardener or curing agent.
A polyurethane coating is really a liquid plastic which dries to form a paint-like film on a substrate. The properties of a polyurethane can be manipulated by the types of isocyanates and polyols which are used to make it. This enables different formulations to be used to suit a customer’s specific needs.
Polyurethane coating provides durability, resistance to chemicals, water, abrasion, and temperature, as well as an attractive non- fading glossy finish.
Power Coatings have a select range of proven, durable polyurethanes for most applications.
The choice of a coating type and application is determined by the customer’s requirements, the substrate type, working conditions, chemical resistance needed, physical requirements of the coating e.g. flexibility, abrasion resistance, fire resistance, non slip etc.
