Micronized oxidized polyethylene wax (MPOW) can serve several purposes in nitrocellulose lacquers, enhancing various properties of the lacquer formulation. Here are some common uses of MPOW in nitrocellulose lacquers:

Surface Protection

MPOW can act as a surface protectant, providing a barrier against moisture, chemicals, and abrasion. This helps to improve the durability and longevity of the lacquer coating.

Enhanced Gloss

By incorporating MPOW into nitrocellulose lacquers, manufacturers can achieve a higher gloss finish on the coated surface. The wax particles help to reflect light, resulting in a shinier appearance.

Improved Scratch Resistance

MPOW can enhance the scratch resistance of nitrocellulose lacquers, making the coated surface more resistant to damage from everyday wear and tear.

Reduced Blocking

Blocking refers to the tendency of coated surfaces to stick together when pressed against each other, especially under high temperatures. MPOW can act as an anti-blocking agent, reducing this tendency and improving the stackability of coated materials.

Enhanced Flow and Levelling

MPOW can improve the flow and levelling characteristics of nitrocellulose lacquers, resulting in a smoother and more uniform coating. This helps to reduce surface defects such as brush marks or orange peel texture.

Anti-Settling Agent

In formulations with high solids content, MPOW can help prevent settling of pigments or other solid additives, ensuring uniform distribution throughout the lacquer.

Matting Agent

In some cases, MPOW can be used as a matting agent to reduce the gloss level of nitrocellulose lacquers, providing a matte or satin finish.

Improved Application Properties

The addition of MPOW can improve the application properties of nitrocellulose lacquers, such as brushability, sprayability, and recoatability.
