DISPERBYK® 103 is a wetting and dispersing additive specifically designed for solvent-borne matting agent pastes. It functions as both a dispersant and a wetting agent, ensuring smooth and efficient dispersion in solventborne coatings, including wood coatings. This additive is compatible with wood surfaces and enhances the performance of industrial additives like matting agents in coating formulations.

Special Features and Benefits:

  • The additive is used to produce highly concentrated matting agent pastes.
  • Such pastes are fluid, stable upon storage, easy to utilize, and capable of being automatically dosed into the system.
  • These matting agent pastes can also be post-added to adjust the degree of matting.
  • The gloss reduction of matting agent pastes produced with DISPERBYK® 103 may be lower than that of matting agents utilizing dry incorporation.

Recommended Use:

DISPERBYK® 103

Incorporation and Processing Instructions:

  • For optimum performance, the additive must be incorporated into the millbase.
  • Prepare paste resin, mix with the solvent and the additive, then add the matting agent.
  • Example: Grinding resin (60% solution), 30 parts;DISPERBYK® 103, 12 parts; solvent, 40 parts; matting agent, 18 parts.

Storage & Handling

Storage and Transportation
  • At temperatures below 10 °C, DISPERBYK® 103 has a tendency to cloud and separate.
  • In this case, please heat the product to a temperature of approx. 35 °C and then stir.
