Two Component Short Oil Alkyd Resin / Water Based Pu Resin Wear Resistance

Two Component Short Oil Alkyd Resin / Water Based Pu Resin Wear Resistance

Two-component polyurethane coating Introduction

Two-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.

Two-component polyurethane coating Feature

1. Excellent wear resistance
2. Excellent chemical and oil resistance
3. Strong adhesion
4. Low temperature curing performance
5. High decorative performance
6. 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.
7. High temperature resistance and low temperature resistance.
8. The film is non-toxic after curing.
9. Environmentally friendly low voc coating

Polyurethane paint is polyurethane paint. It is strong in film, full of luster, strong adhesion, water resistant, abrasion resistant and corrosion resistant. It is widely used in high-grade wood furniture and can also be used on metal surfaces.
Characteristics of two-component polyurethane paint: Hydroxy-curable polyurethane paint has the advantages of being dry at room temperature, low toxicity, tough film, high gloss, good adhesion, corrosion resistance, oil resistance and water resistance. It is used in metal and cement. , wood and rubber, leather and other materials. Catalytic curable polyurethane lacquer coating has good oil, water, acid and alkali resistance, organic solvent resistance, and has good adhesion and wear resistance. It is generally used as a surface coating for wood, concrete, etc. Floor paint). Two-component polyurethane coatings generally consist of an isocyanate prepolymer (also known as a low molecular urethane polymer) and a hydroxyl-containing resin, commonly referred to as a curing agent component and a main component.
