Features Of Albemarle PERGOPAK M4 Matte Agent

  1. Highly efficient silica-based matting agent delivering consistent, uniform surface texture in clear and pigmented coatings.

  2. Optimized particle size distribution for excellent transparency retention and minimal haze in topcoats.

  3. Good dispersion stability in both solventborne and waterborne systems without requiring high-shear pre-dispersion.

  4. Low abrasiveness to application equipment and substrates, supporting extended production runs and reduced maintenance.

  5. Chemically inert and thermally stable up to 300 °C, ensuring compatibility with baking finishes and UV-curable systems.

Typical Applications Of Albemarle PERGOPAK M4 Matte Agent

  1. Automotive OEM and refinish clearcoats requiring controlled gloss reduction without compromising depth or clarity.

  2. Architectural and industrial maintenance coatings, including acrylic and polyurethane topcoats for metal and wood substrates.

  3. UV-curable wood coatings for furniture and flooring where low VOC, rapid cure, and matte aesthetics are critical.

  4. Plastic coatings for electronics housings, appliances, and consumer goods demanding scratch resistance and soft-touch feel.

  5. High-performance coil coatings for pre-painted metal used in building panels and HVAC components.
