DISPERBYK® 109 is a solvent-free wetting and dispersing additive designed for solvent-borne coatings based on medium-polar to non-polar TPA or alkyd resins. It is highly effective in dispersing inorganic pigments and improving color paste acceptance. This additive is compatible with alkyd resins and enhances the performance of solventborne coatings. As a dispersant and wetting agent, DISPERBYK® 109 facilitates better pigment dispersion and formulation efficiency.

Coatings Industry Application

Special Features and Benefits:

  • By using DISPERBYK® 109, the color paste acceptance of medium-polar to non-polar TPA and alkyd resin coatings is greatly improved. DISPERBYK-109 can also be post-added to the coating system.
  • However, this should be done before the addition of the color paste.
  • DISPERBYK® 109 is also used to disperse inorganic pigments (titanium dioxide and fillers) in TPA and alkyd resin coatings.

Recommended Levels:

  • 1-2% additive (as supplied) based upon titanium dioxide.
  • As post-additive to improve color acceptance: 0.3-1% additive (as supplied) based upon total formulation.
  • The above recommended levels can be used for orientation.
  • Optimal levels are determined through a series of laboratory tests.

Incorporation and Processing Instructions:

  • For optimum performance, the additive must be incorporated into the millbase before addition of pigments.
  • The resin and solvent components of the millbase are pre-mixed and then the additive is slowly incorporated while stirring continuously.
  • Do not add the pigments until the additive has been fully distributed.
  • To improve color acceptance, the additive can also be post-added into the coating.

Special Note:

  • When added at concentrations of 1% or higher (based upon total formulation), the effects on drying and yellowing should be tested.
