What is the gloss range for Matte ACP? Is it different from “Flat” finish?

  • A: Matte (or Satin) ACP typically has a gloss range of 5 GU to 30 GU (measured at 60°). The industry often further defines:
  • Full Matte/Flat: ~5-10 GU, almost no gloss, soft texture.
  • Matte/Satin: ~10-25 GU, very subtle, subdued luster, silky feel.
    “Flat” can be considered the lowest gloss category within matte. Matte surfaces are achieved by adding matting agents to the coating formula and special processes.
