ACRYSOL™ I-62A

ACRYSOL™ I-62A Emulsion is an aqueous alkali-soluble acrylic copolymer which has broad utility as a dispersant for organic and inorganic pigments. As a pigment dispersant, it offers excellent dispersion for whites and a variety of deep-tone formulations. It is especially useful in formulations designed for thermosetting applications. It is a waterborne colloidal dispersion containing both carboxylic acid and hydroxyl functionality, and as such will crosslink with melamine-formaldehyde or urea-formaldehyde resins, thereby becoming part of the polymer matrix and improving the film properties.

Formulation Information

Neutralization: ACRYSOL™ I-62A Emulsion is supplied at 50% solids at low pH. Before pigment dispersion, ACRYSOL I-62A Emulsion should be diluted and neutralized, as in the following examples:

Material Example 1: Parts by Weight

Example 2: Parts by Weight

ACRYSOL™ I-62A Emulsion (50%) 10.0 50.0
Water 10.0 47.1
DMAE (50% aqueous solution) 2.0  
Ammonia (28%)   2.9

 

In typical applications, ACRYSOL I-62A Emulsion is diluted to 25% weight solids, then neutralized with a quantity of dimethylaminoethanol (DMAE) roughly equal to 20% weight solids of ACRYSOL I-62A Emulsion. The final solution pH should be approximately 8.7 to 9.5, independent of amine, i.e., whether ammonia or tertiary amine is used. For thermoset coating formulations containing melamine-formaldehyde resins, a tertiary amine such as DMAE or triethylamine (TEA) is suggested for best formulation stability.

Efficiency:
A level of 2 to 4% resin solids of ACRYSOL™ I-62A Emulsion, based on total pigment weight, is usually sufficient for good pigment dispersion and dispersion stability. The actual amount of ACRYSOL I-62A Emulsion solids required is dependent on the specific choice of pigments. Higher levels may be necessary with carbon blacks or for milling organic pigments.

Water Resistance and Durability:
ACRYSOL™ I-62A Emulsion is an excellent choice with thermosetting polymers because it offers maximum water resistance by becoming incorporated into the polymer matrix. The use of a non-reactive dispersant could cause poorer water resistance. Durability data demonstrates that the coatings based on ACRYSOL I-62A Emulsion perform comparably to those which employ the conventional dispersants.
