2 Component Polyurethane coating Introduction

2 Component Polyurethane coatings have excellent film forming temperature, strong adhesion, good wear resistance, high hardness, good chemical resistance and weather resistance, and are widely used as industrial protection, wood furniture and automotive coatings. Waterborne two-component polyurethane coatings combine the high performance of two-component solvent-based polyurethane coatings with the low VOC content of waterborne coatings, making them a research hotspot in the coatings industry. The aqueous two-component polyurethane coating is composed of an -OH-containing aqueous polyol and a -NCO-based low-viscosity polyisocyanate curing agent, and its coating properties are mainly determined by the composition and structure of the hydroxy resin.

2 Component Polyurethane coating Feature

1. Strong adhesion
2. Low temperature curing performance
3. High decorative performance
4. Performance diversity, adjustability. Through the improvement of the formula, the polyurethane coating film can be made into a high hardness coating film, or can be made into an elastic coating film with excellent flexibility, which greatly enhances the application range of the polyurethane coating.
5. High temperature resistance and low temperature resistance.
6. The film is non-toxic after curing.
7. Environmentally friendly low voc coating
