Q1: How does Acrysol TT935 differ from conventional alkali-swellable thickeners?
A: Acrysol TT935 is a hydrophobic alkali-swellable emulsion (HASE) thickener, designed to provide enhanced rheology control and improved compatibility with surfactants and co-solvents compared to traditional ASE thickeners. Its hydrophobic modification enables better film formation, reduced water sensitivity, and improved resistance to shear during application.
Q2: What types of formulations is Acrysol TT935 typically used in?
A: It is widely used in architectural coatings—including interior and exterior flat and low-sheen paints—as well as industrial maintenance coatings and some specialty waterborne adhesives where robust viscosity build, sag resistance, and spatter control are required.
Q3: How should Acrysol TT935 be incorporated into a formulation?
A: It is generally added late in the let-down stage, after pH adjustment to ≥8.0, to ensure optimal swelling and performance. Pre-dilution with water or compatible solvent may aid dispersion, and gentle mixing is recommended to avoid excessive air entrapment.
Q4: Does Acrysol TT935 offer any advantages in freeze-thaw stability?
A: When properly formulated—particularly with appropriate co-thickeners and stabilizers—Acrysol TT935 contributes to improved rheological recovery after freeze-thaw cycling, helping maintain consistent viscosity and application properties across temperature variations.
