Additional Information

This ammonium salt of a hydrophobic copolymer Dispersant offers an unmatched combination of benefits, including:

  • Stability in paints containing zinc oxide and other reactive pigments
  • Improved flow and film-build when used with nonionic rheologymodifiers
  • Enhanced gloss potential
  • Improved corrosion resistance

In gloss formulations, including high-gloss acrylic enamels, TAMOL® 681 Dispersant permits the full development of the gloss potential of the binder. TAMOL® 681 Dispersant is highly compatible with HEUR nonionic rheology modifiers such as ACRYSOL® RM-995 and ACRYSOL® RM- 5000 Rheology Modifiers. When used with these thickeners, TAMOL® 681 Dispersant improves flow and film-build and provides an alkyd-like feel when brushing. TAMOL® 681 Dispersant is well suited for formulating metal and wood primers and stain and corrosion-resistant topcoats for a variety of substrates.

Technical Details & Test Data

Dispersing Efficiency

TAMOL® 681 DISPersant should be tested at 3.0% to 5.0% active ingredient based on total pigment weight. It is important to determine the proper level for the finished paint formulation. If a low level is used, the dispersion may be incomplete providing an inadequate grind that may not maximize gloss, hiding, or stability. High levels of dispersant may lead to increased water sensitivity.
