Matting Agents

Matting agents are chemical substances used in paint and coating systems to reduce surface gloss, giving a matte appearance. They achieve this by altering light scattering on the paint film. Matting agents can also help prolong the life of plastics and elastomers by preventing their degradation.

Common types of matting agents include

  • Silica: The most common matting agent, available in powder or gel form. Silica scatters light at different angles to create a matte appearance.
  • Aluminum Hydroxide: Functions similarly to silica and provides a matte finish.
  • Calcium Carbonate: A powdered matting agent often used as a low-cost option.
  • Organic Matting Agents: Can be synthetic or naturally sourced and are typically used to achieve a smoother and more homogeneous matte finish.

Benefits of using matting agents include

  • Reducing gloss to prevent eye strain.
  • Masking stains and hiding surface imperfections.
  • Providing a deeper and more luxurious appearance.
  • Extending the life of plastics and elastomers by preventing degradation.
