Q1: What type of rheology does RM-895 provide in waterborne coatings?
A: RM-895 is a non-ionic, hydrophobically modified polyurethane (HEUR) thickener that delivers strong pseudoplastic flow behavior—providing excellent sag resistance while maintaining good leveling and brush/roll application properties.
Q2: Is RM-895 compatible with high-shear pigment dispersions and common co-thickeners?
A: Yes—RM-895 exhibits broad compatibility with typical waterborne architectural and industrial coating systems, including those containing acrylic or associative thickeners. It performs well in formulations with high-shear dispersed pigments and is often used in combination with cellulosic or acrylic thickeners to fine-tune rheological profiles.
Q3: How should RM-895 be incorporated into a formulation for optimal performance?
A: RM-895 is typically added post-emulsification, either neat or pre-diluted in water or glycol ether solvents. To ensure uniform dispersion and avoid localized over-thickening, it is recommended to add gradually under moderate agitation and allow sufficient time for full hydration and network development—usually 15–30 minutes depending on formulation complexity and temperature.
Q4: Does RM-895 offer good freeze-thaw stability in formulated systems?
A: RM-895 contributes to improved freeze-thaw stability when properly integrated into robust formulations. Its non-ionic nature avoids salt sensitivity issues common with some ionic thickeners, though overall system stability depends on the full binder/pigment/additive package—and testing under intended storage conditions is recommended.
