Frequently Asked Questions

Titanium Dioxide R-2219 Properties

Titanium dioxide R-2219 is a specific grade of titanium dioxide pigment that possesses several desirable properties, making it well-suited for use in powder coating masterbatch. Here are some of the key characteristics of R-2219 that make it a popular choice:

1. High Whiteness: Titanium dioxide is a white pigment, and R-2219, in particular, exhibits high whiteness. This property is essential for achieving a bright and clean white color in powder coatings.

2. Blue Undertone: The blue undertone refers to a subtle bluish tint in the white pigment. It can help balance and enhance the overall color appearance, especially in certain shades of white and light-colored coatings.

3. Excellent Dry Flow Performance: Dry flow performance is crucial for powder coatings as it affects how easily the pigment can be dispersed and mixed with other components. R-2219's excellent dry flow performance ensures uniform distribution and dispersion within the coating mixture, leading to a consistent and smooth finish.

4. High Hiding Power: Hiding power, also known as opacity, refers to a pigment's ability to conceal the underlying substrate or previous coating layers. Titanium dioxide R-2219's high hiding power allows it to cover imperfections and provide excellent coverage, reducing the number of coating layers required.

Due to these favorable properties, R-2219 is widely utilized in powder coating masterbatch. Masterbatch is a concentrated mixture of pigments or additives that is added to the base powder coating formulation to achieve specific colors or performance enhancements. The inclusion of R-2219 in the masterbatch ensures that the desired whiteness, hiding power, and color undertone are consistently achieved in the final powder coating product.
