Application Advice/Typical Applications

For additional information on this product please contact our techncial service team.

ROHAGIT A 220 D is an ideal dispersing agent for a wide range of aqueous-based coatings and can be used as supplied. ROHAGIT A 220 D releases ammonia during the drying process and therefore has little impact on water and alkaline resistance of the dry film. Use in the pH range 5 -10.5 and temperatures lower than 70°C to minimise potential loss of volatile ammonia. Once formulated the acrylic polymer based ROHAGIT A 220 D imparts improved storage stability in both the pigment dispersion and the formulated paint. Formulations show little or no adverse reaction to changes in pH or temperature. The recommended level of use is 0.3 – 2.0%, based on total pigment weight

Shipping and Storage
