WPA COATING
WPA coating is a water-based polyurethane coating with good environmental performance and excellent physical and mechanical properties. The following is the basic formula for WPA coating:
Ingredient content (%)
Waterborne polyurethane resin: 20-30
Deionized water: 40-50
Additives (such as wetting agents, defoamers, thickeners, etc.): 5-10
Color fillers (such as titanium dioxide, talc powder, etc.): 10-20
Moderate pH: regulator
Preparation method
1, Add deionized water into the dispersion tank and start the mixer;
2, Add color fillers and additives in sequence while stirring, and stir evenly;
3, Add water-based polyurethane resin and continue stirring until uniform;
4, Finally, add a pH regulator to adjust the pH value to 7-8;
Filter out the material to obtain WPA coating.
Attentions
The proportion of ingredients in the formula can be adjusted according to specific needs;
The selection of additives should be based on the specific application field and performance requirements of the coating;
During the preparation process, attention should be paid to controlling the temperature and stirring speed to ensure product quality.
The above is a basic WPA coating formula and its preparation method, and the specific formula may vary depending on different manufacturers and application scenarios. Suggest adjusting and optimizing according to specific needs in practical applications.
