Q1: What is the primary application of SETAQUA B E 270 in waterborne coatings?
A: SETAQUA B E 270 is a water-reducible polyester resin designed primarily for high-performance, low-VOC industrial maintenance and protective coatings, including metal primers and topcoats where good gloss retention, flexibility, and corrosion resistance are required.
Q2: Is SETAQUA B E 270 compatible with common waterborne crosslinkers?
A: Yes, it is formulated to be compatible with standard waterborne amino resins and polyisocyanate crosslinkers, enabling robust cure performance at ambient or elevated temperatures depending on the system design.
Q3: How should SETAQUA B E 270 be dispersed or diluted in aqueous systems?
A: It is typically added to water under moderate agitation and may require pH adjustment (e.g., with tertiary amines) to achieve stable dispersion. Pre-dilution with deionized water is recommended before incorporation into the full formulation.
Q4: Does SETAQUA B E 270 offer good compatibility with pigments and fillers?
A: Yes, it demonstrates good wetting and stabilization properties for common inorganic pigments and extenders used in industrial waterborne coatings, supporting formulations with low settling tendency and acceptable rheology.
