Q1: What types of coating systems is ADDAPT PolySurF HP compatible with?
A: ADDAPT PolySurF HP is engineered for compatibility with waterborne and solvent-based acrylic, polyurethane, epoxy, and alkyd coatings. It disperses readily during standard high-shear mixing and maintains stability across a broad pH range typical of architectural, industrial, and protective coating formulations.
Q2: How does ADDAPT PolySurF HP achieve flame retardancy without compromising film integrity?
A: It functions through an intumescent mechanism—expanding upon exposure to heat to form a thermally insulating char layer that shields the underlying substrate. Its polymeric structure ensures strong interfacial adhesion within the coating matrix, minimizing leaching and preserving mechanical properties such as flexibility and adhesion after curing.
Q3: Is ADDAPT PolySurF HP suitable for interior decorative coatings requiring low VOC and odor compliance?
A: Yes—it is non-halogenated, free of antimony trioxide, and contains no volatile organic solvents or plasticizers. Its formulation supports low-VOC and low-odor coating systems compliant with major indoor air quality guidelines for residential and commercial applications.
Q4: What is the recommended dosage range for effective flame retardancy in standard coating formulations?
A: Dosage depends on the base resin system, film thickness, and target fire performance (e.g., UL 94, ASTM E84 Class A/B). It is typically used at low concentrations—generally ranging from 0.1% to 2% by weight of total formulation—and optimized via small-scale fire testing and rheological evaluation.
