Q1: What is the primary thickening mechanism of BR100P?
A: BR100P functions via associative thickening—its hydrophobic end groups interact with other hydrophobic sites in the formulation (e.g., surfactants, polymer particles, or resin micelles), forming a reversible, three-dimensional network that imparts viscosity and rheological control without significantly increasing low-shear viscosity.
Q2: Is BR100P compatible with anionic and cationic systems?
A: As a nonionic polyurethane, BR100P exhibits broad compatibility with anionic, cationic, and amphoteric surfactants and polymers. However, strong ionic interactions or high electrolyte concentrations may partially screen hydrophobic associations, so performance should be verified in the final formulation.
Q3: How does BR100P perform under freeze-thaw conditions?
A: BR100P demonstrates good freeze-thaw stability in properly formulated aqueous systems due to its water-soluble, nonionic nature and absence of salt-sensitive functional groups—making it suitable for architectural coatings and other applications requiring storage at low temperatures.
Q4: Can BR100P be used in high-solids or low-VOC formulations?
A: Yes—BR100P is well-suited for low-VOC and high-solids systems because it delivers efficient thickening at low dosage levels and does not require co-solvents or pH adjustment, supporting formulation strategies aligned with modern environmental and regulatory expectations.
