Q1: What types of industrial coatings is Efka PB 2010 Defoamer typically used in?
A: Efka PB 2010 is widely employed in water-based architectural and industrial coatings, including interior and exterior wall paints, primers, and basecoats, where rapid foam suppression and long-term foam stability control are required during manufacturing and application.
Q2: How does Efka PB 2010 differ from silicone-based defoamers?
A: Unlike many silicone-based systems, Efka PB 2010 is a non-silicone, polyether-modified polymer defoamer designed to minimize surface defects such as craters, pinholes, or gloss mottle—making it especially suitable for high-gloss and sensitive decorative coatings where silicone contamination must be avoided.
Q3: What is the recommended addition point and method for optimal performance?
A: For best results, Efka PB 2010 should be added during the let-down phase, after pigment grinding and before thickener addition. It is generally introduced under moderate agitation and is compatible with both low- and high-shear mixing conditions commonly used in paint production.
Q4: Is Efka PB 2010 compatible with common thickeners and rheology modifiers?
A: Yes—Efka PB 2010 demonstrates good compatibility with associative and non-associative thickeners, including HEC, HASE, and ASE types, as well as cellulose ethers and polyurethane thickeners, without compromising viscosity stability or causing phase separation.
Q5: Can Efka PB 2010 be used in low-VOC or zero-VOC formulations?
A: Yes—Efka PB 2010 is formulated to support low- and zero-VOC coating systems. It contains no regulated VOC solvents and contributes negligible volatile content, aligning with modern environmental and regulatory expectations for sustainable paint development.
