Korning FoamStar ST2410AC Defoamer – Frequently Asked Questions (FAQ)
Q1: What is the primary application area for FoamStar ST2410AC?
A: FoamStar ST2410AC is specifically formulated for use in water-based industrial coatings, including architectural paints, industrial maintenance coatings, and wood finishes—where robust foam control is required during both manufacturing and application stages.
Q2: How does ST2410AC differ from silicone-based defoamers?
A: Unlike conventional silicone defoamers, ST2410AC is a non-silicone, polymer-based system designed to minimize surface defects such as craters, pinholes, or gloss inconsistencies—making it especially suitable for high-appearance coating systems where silicone contamination must be avoided.
Q3: Is ST2410AC compatible with common rheology modifiers and biocides used in paint formulations?
A: Yes, ST2410AC demonstrates good compatibility with typical associative thickeners (e.g., HEUR), cellulosics, and widely used isothiazolinone and benzisothiazoline biocides. However, compatibility should always be verified in the final formulation due to potential interactions with specific chemistries.
Q4: What is the recommended addition method and timing for optimal performance?
A: For best results, ST2410AC should be added during the let-down stage, after pigment dispersion and before thickener addition. It is typically used at low concentrations and benefits from gentle but sufficient mixing to ensure uniform distribution without reintroducing air.
Q5: Does ST2410AC affect film formation or long-term stability of the coating?
A: When used within the recommended dosage range, ST2410AC does not interfere with film formation, adhesion, or storage stability. Its polymeric structure is designed to remain inert in the dried film and does not migrate or bloom under standard curing conditions.
