Q1: What type of rheology does Rheotech TM2800 provide in waterborne formulations?
A: Rheotech TM2800 is an associative thickener that delivers pronounced pseudoplastic (shear-thinning) behavior, enhancing sag resistance at rest while enabling good flow and leveling during application. It imparts strong mid-shear viscosity control, supporting brush/roller performance and spray atomization.
Q2: Is Rheotech TM2800 compatible with common surfactants and co-thickeners used in architectural coatings?
A: Yes, TM2800 exhibits broad compatibility with nonionic and anionic surfactants, as well as with cellulosic thickeners and other associative acrylics. Compatibility should be verified empirically in the final formulation due to sensitivity to ionic strength and surfactant HLB balance.
Q3: How should Rheotech TM2800 be incorporated into a coating formulation?
A: It is typically added during the let-down stage, after pigment dispersion and pH adjustment. Pre-dilution with water or a compatible solvent is recommended for uniform dispersion. Avoid high-shear addition directly to highly ionic or low-pH phases to prevent premature association or instability.
Q4: Does Rheotech TM2800 offer any benefit in terms of freeze-thaw stability?
A: While not a primary freeze-thaw stabilizer, TM2800’s associative network can contribute to improved structural resilience during freeze-thaw cycling when formulated with appropriate stabilizers and co-binders—though performance must be validated per specific system requirements.
