What is polyurethane?

Polyurethane is a petroleum-based product used as a coating and adhesive. It is plastic in liquid form. Polyurethane is available in two types: oil-based polyurethane and polyurethane. The application of oil-based polyurethane paint leaves the amber color and takes longer to dry. When dried, oil-based polyurethane emits a bad smell.

On the other hand, water-based amber leaves no color and dries faster than oil-based amber. Although it is more expensive than oil-based and less resistant to heat and chemicals.
