HASE Thickener

Regional Product Availability       • Asia-Pacific

Description

      ACRYSOL™ TT-615 Thickener is an alkali swellable acrylic polymer emulsion used as either a primary or ancillary thickener in coatings. This product offers viscosity build  comparable to high molecular weight HEC thickeners at low shear levels. Viscosity is developed by neutralization to a pH of 7 to 10. ACRYSOL TT-615 Thickener offers greater roller spatter resistance than cellulosic thickeners, but with a more pseudoplastic rheology profile. The liquid physical form of ACRYSOL TT-615 Thickener facilitates its incorporation into grinds and letdowns.

Key Features

                               • Facilitates the formulation of textured finish paints.

                               • Excellent sag resistance.

                               • Very good resistance to roller spattering.

                               • Low viscosity, water-based emulsion.

                               • Excellent film build capability.

                               • Offers resistance to microbe and enzyme attack.

Benefits

                           • Offers improved application properties and cost effectiveness than cellulosic thickeners.

                               • Easy to handle and incorporate into formulations.

                               • Facilitates the formulation of stable latex paints.

Product Addition        

ACRYSOL TT-615 Thickener is an alkali swellable thickener, which achieves its thickening effect when it is neutralized. When added full strength to the letdown, care must be taken to avoid local shock or gross paint instability. There must be sufficient base in the system before addition of ACRYSOL TT-615 Thickener to fully neutralize the thickener and still remain on the alkaline side over the normal shelf life of the paint. ACRYSOL TT-615 Thickener should be added slowly with good agitation. If this approach is not sufficient, ACRYSOL TT-615 Thickener can be diluted 1:1 or 2:1 with water prior to addition to the  letdown to reduce the chance for shocking.
