TAMOL™ Dispersants

TAMOL™ Dispersants Add Extras

TAMOL™ Dispersants from Dow deliver more ways to formulate a perfect can of paint. They come in a range of chemistries that optimize the pigment grind and offer added extras, such as enhanced gloss and stain resistance. Our dispersants are backed by industry-leading technical service support. They’re also supplemented by a dedicated R&D team focused on developing products to meet your performance goals and VOC targets.

The TAMOL™ Family of Dispersant Solutions

TAMOL™ Dispersants span a range of chemistries, from highly efficient polyacid homopolymers to film-enhancing hydrophilic and hydrophobic polyacid copolymers. Each offers a unique set of properties, providing an unparalleled level of choice and versatility.

How TAMOL™ Dispersants Work

Paint hiding, gloss and durability rely on even distribution of pigment particles. During paint manufacturing, pigment clusters are separated in the grind phase. However, they will re-agglomerate during letdown in the absence of an effective dispersing agent. TAMOL™ Dispersants keep pigment particles separated through charge-charge repulsion. They contribute to more efficient milling in the grind phase and offer lasting performance benefits.

Subtract Solvent and Add Gloss
TAMOL™ 2011 Dispersant is a next-generation hydrophobic copolymer offering efficient pigment stabilization in an easy-handling formulation that is solvent-free and APEO-free.* With little to no loss of tint strength at higher use levels, TAMOL™ 2011 Dispersant offers formulation flexibility and the opportunity to add more gloss, more stain resistance and more water resistance to low- and ultra-low-VOC paints.
*Manufactured without added solvent or APEO surfactant.

More Gloss
Higher levels of TAMOL™ 2011 Dispersant offer better gloss, as demonstrated above in a RHOPLEX™ HG-706 Acrylic Emulsion high-gloss formulation (19% PVC/34% VS).

More Stain Resistance
Higher use levels of TAMOL™ 2011 Dispersant offer better stain resistance, as demonstrated above in a RHOPLEX™ HG-706 Acrylic Emulsion high-gloss formulation (19% PVC/34% VS).

 

Chemistry Categories
The most prevalent dispersant molecules are polymeric dispersants. These are divided into two categories:

  1. Polyacid homopolymers
  2. Polyacid copolymers

The category of dispersant chosen depends on:

  • Efficiency
  • Rheology modifier compatibility
  • ZnO compatibility
  • Other film performance criteria expected for a particular formulation
