Single-component Polyurethane Paint, Two-component Polyurethane Paint, Polyurethane Paint, Purchasing Waste Polyurethane Coatings, Purchasing Polyurethane Resin

Polyurethane coatings are a common type of paint, which can be divided into two-component polyurethane coatings and one-component polyurethane coatings. Two-component polyurethane coatings are generally composed of isocyanate prepolymers (also known as low molecular weight polyisocyanates) and hydroxyl-containing resins, commonly referred to as the hardener component and the base component.

Based on the different types of hydroxyl groups, they can be categorized into various types such as acrylic polyurethane, alkyd polyurethane, polyester polyurethane, polyether polyurethane, and epoxy polyurethane, among others.

Categorized by packaging type, there are single can polyurethane paint, double can polyurethane paint, and triple can polyurethane paint. For home decoration, triple can polyurethane paint (which includes one can of base paint, one can of hardener, and one can of thinner) is commonly used.

The product is categorized into five main types based on its composition and film-forming mechanism: Polyurethane Modified Oil Coatings, Vapour-Curing Polyurethane Coatings, Encapsulated Polyurethane Coatings, Curing Catalyst Polyurethane Coatings, and Hydroxyl Curing Polyurethane Coatings.
