TAMOL™ 1254 Polyacid Pigment Dispersant For Latex Paints


TAMOL 1254 is a versatile, low-cost, low-foaming polyacid dispersant that provides outstanding performance in a wide range of latex paint formulations. It is recommended for low sheen flats through gloss acrylic, styrene-acrylic and vinyl acrylic formulations. In addition to good efficiency, this polyacid dispersant provides excellent stability and color acceptance even in formulations containing zinc oxide.

TAMOL 1254 dispersant is supplied at 35% solids and is both ammonia and formaldehyde free. It is highly compatible with anionic HASE associative rheology modifiers. TAMOL 1254 dispersant provides excellent performance for viscosity stability and color acceptance with ACRYSOL™ Designed Rheology™ products.

Dispersing Efficiency

TAMOL 1254 pigment dispersant should be tested at 0.5% to 1.0% 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 will not maximize gloss, hiding or stability. High levels of dispersant may lead to increased water sensitivity.
