VAPOROXOL-3F for Powder Coatings

VAPOROXOL®-3F is based on highly hygroscopic Calcium Oxide (CaO) chemistry. Its surface-treated particles disperse uniformly within the powder matrix during dry-blending and extrusion, where they rapidly and selectively absorb residual moisture via exothermic CaO-H₂O reaction before the main curing process begins.

Yes — VAPOROXOL®-3F is surface-treated to provide controlled reactivity, safer handling, and reduced dustiness compared to raw CaO, making it suitable for use in standard twin-screw extrusion manufacturing environments with normal PPE precautions.

VAPOROXOL®-3F specifically prevents moisture-induced defects including: surface porosity, blistering, foam generation, gloss reduction, haze formation, and pinholes — defects most commonly associated with PU and Epoxy powder coatings cured in humid conditions or after extended storage.

Yes — guideline formulations show VAPOROXOL®-3F used in combination with MICRON MICA 1240 PY and FUSYL T-72 in Epoxy powder coatings, delivering enhanced barrier properties, film integrity, and chemical resistance while maintaining equivalent mechanical performance (Impact, Adhesion, Flexibility, Pencil Hardness).
