DISPERBYK® 107

1 of 58 products in this brand
DISPERBYK® 107 is a wetting and dispersing additive designed for solvent-borne architectural coatings and pigment concentrates based on alkyd resins. It is suitable for use with all pigments, offering high color strength, high pigment loading, and improved transparency. This additive helps reduce viscosity and enhances gloss, making it ideal for achieving high-quality finishes in coatings. As both a dispersant and wetting agent, DISPERBYK® 107 improves dispersion efficiency and performance in alkyd-based formulations.

Coatings Industry Application

Special Features and Benefits:

  • The additive deflocculates pigments through steric stabilization of the pigments.
  • Due to the small particle size of the deflocculated pigments, high gloss is achieved and the color strength is improved.
  • In addition, this product increases the transparency and hiding power of pigments and reduces viscosity.
  • Subsequently, it improves leveling and allows for higher pigment loading.

Recommended Use:

  • The additive is especially recommended for architectural coatings to stabilize titanium dioxide, fillers, and other inorganic and organic pigments.
  • The percentage of fillers can often be increased without reducing gloss.
  • White coatings stabilized with DISPERBYK® 107 do not exhibit flooding and floating and show improved color acceptance when using universal colorants.
  • The additive is suitable for formulating pigment concentrates on the basis of long oil alkyds.

Incorporation and Processing Instructions:

  • For optimum performance, the additive must be incorporated into the millbase before addition of pigments.
