Q1: What type of rheology does CFC-3150 provide in polyurethane systems?
A: CFC-3150 is a non-ionic, associative polyurethane thickener that delivers pronounced shear-thinning behavior and excellent sag resistance, with good recovery after shear—ideal for coatings and sealants requiring balanced application and vertical hold.
Q2: Is CFC-3150 compatible with anionic surfactants and common co-thickeners?
A: Yes, CFC-3150 exhibits broad compatibility with anionic surfactants, cellulose ethers, and acrylic thickeners, though pre-testing is recommended when combining with high-ionic-strength additives or strongly cationic components to avoid potential viscosity instability.
Q3: How should CFC-3150 be incorporated into waterborne PU formulations?
A: It is typically added during the post-addition stage—after primary dispersion and pH adjustment—under moderate agitation. Pre-dilution with water or a compatible solvent may aid uniform dispersion, especially in low-shear processes.
Q4: Does CFC-3150 contribute to film formation or affect final coating properties?
A: As a non-volatile rheology modifier, CFC-3150 remains in the dry film and may influence surface feel and intercoat adhesion; however, it does not act as a film former. Its impact on gloss, hardness, or flexibility is formulation-dependent and generally minimal at typical use levels.
Q5: What storage conditions are recommended for optimal shelf life?
A: Store in original sealed containers at temperatures between 5°C and 35°C, away from direct sunlight and freezing conditions. Prolonged exposure to extreme heat or moisture may affect viscosity stability and performance consistency.
