Q1: What is the primary function of Acrysol RM-12W in waterborne coatings and inks?
A: Acrysol RM-12W is a hydrophobically modified polyurethane (HEUR) associative thickener designed to provide efficient rheology control—particularly high-shear viscosity and flow/leveling balance—in low-VOC, waterborne architectural paints, industrial coatings, and pigment dispersions.
Q2: How does RM-12W differ from cellulosic or acrylic thickeners?
A: Unlike non-associative thickeners, RM-12W functions through reversible hydrophobic associations in aqueous systems, delivering superior sag resistance, spatter resistance, and brush/roller feel—without the high low-shear viscosity or poor compatibility often seen with cellulose ethers or associative acrylics.
Q3: Is RM-12W compatible with common co-thickeners and surfactants used in architectural paints?
A: Yes—RM-12W is generally compatible with nonionic surfactants and can be effectively combined with other associative thickeners (e.g., HEUR or HASE types) for synergistic rheology tuning. However, compatibility should be verified experimentally when used with high levels of anionic surfactants or certain biocides.
Q4: What is the recommended addition method for optimal performance?
A: RM-12W is typically added during the let-down stage, either neat or pre-diluted with water or a water-miscible solvent. To ensure uniform dispersion and avoid localized over-thickening, it should be added slowly with moderate agitation and allowed sufficient time for full associative network development before final pH adjustment or addition of other additives.
