Q1: What type of rheology does CFC-3180 impart to polyurethane dispersions?
A: CFC-3180 is a non-ionic, associative polyurethane thickener that provides strong pseudoplastic flow behavior and excellent sag resistance, particularly in waterborne PU systems. It enhances both low-shear viscosity (for leveling and film formation) and high-shear thinning (for spray or roll application).
Q2: Is CFC-3180 compatible with common co-thickeners or additives used in architectural or industrial coatings?
A: Yes — CFC-3180 demonstrates good compatibility with cellulose ethers, acrylic thickeners, and most defoamers, biocides, and dispersants commonly employed in water-based PU formulations. However, compatibility testing under specific formulation conditions is recommended prior to full-scale use.
Q3: How should CFC-3180 be incorporated into a formulation to ensure optimal performance?
A: It is typically added during the post-addition stage, after primary dispersion and pH adjustment, under moderate agitation. Pre-dilution with water or compatible solvent may improve uniform dispersion. Avoid high-shear mixing for extended periods, as excessive shear can temporarily reduce its thickening efficiency.
Q4: Does CFC-3180 affect the final film properties of polyurethane coatings?
A: When properly formulated, CFC-3180 contributes minimal impact on gloss, clarity, or mechanical film properties such as flexibility and adhesion. Its non-ionic nature helps maintain stability without interfering with crosslinking chemistry in two-component or ambient-cure PU systems.
