PAT-ADD DA 934 is a polymeric dispersing agent for use in industrial solvent-borne paints and pigment concentrates.PAT-ADD DA 934 is specially designed for application in high concentrated pigment dispersions as applied for in-plant tinting purposes. Using PAT-ADD DA 934, results in extremely low viscosity and high transparency properties. Although, being all-round applicable as a dispersing agent for pigment concentrates, PAT-ADD DA 934 is particularly effective as dispersant for furnace carbon blacks and organic pigments.

Properties

PAT-ADD DA 934 is a polymeric dispersing agent exhibiting strong adsorption properties onto a wide variety of pigment surfaces, contributing to best dispersion stability, low viscosity pigment dispersions and high transparency fir fine particle sized pigments.

Benefits
  • Most suitable dispersant for high pigment loaded tinters 
  • Extremely effective for furnace carbon blacks, for extreme jet, blue undertone 
  • Provides excellent color development and transparency 
  • Excellent paint performance, limited unwanted side effects 
  • For automotive refinishes, automotive/OEM, general industrial coatings, coil coatings, wood coatings, pigment concentrates and silk screen printing inks

Application

Standard of the series: pigment dispersant for industrial paints, high concentrated RFPC, incl. carbon black. Polyurethane polymer, multi-anchoring. HMV polymer.

Dosage & Addition

The optimal amount of PAT-ADD DA 934 to be used is system related, but generally is between 10 and 15% PAT-ADD DA 934, calculated on the total weight of pigment concentrate. If used in ready mixed paints, dosages of approx. 1 to 4% are suggested. The product is best added to the mill-base prior to the pigments. For carbon blacks a dosage of 20 to 60% (active ingredient) on pigment is recommended. The optimum concentration to be used depends on the individual requirements and conditions.
