Mica Series for Powder Coatings

Mica is thermally stable up to 1,000°C. MICRON MICA 1240 PY retains its platy structure under high curing and service temperatures, preventing film blistering, maintaining dimensional stability, and preserving adhesion and barrier function in heat-exposed applications.

Yes — mica's naturally high electrical resistivity makes it a preferred functional additive in electrical insulation powder coatings for busbars, transformer components, and switchgear where dielectric performance is required in addition to mechanical protection.

The platelet geometry of mica improves melt flow and film build at edges, welds, and recesses during powder curing, ensuring uniform film thickness and complete coverage in geometrically complex parts — a critical requirement in architectural and structural steel coating applications.

Yes — guideline formulations confirm that MICRON MICA 1240 PY used in combination with VAPOROXOL-3F in Epoxy powder systems delivers enhanced barrier properties, film integrity, and chemical resistance while maintaining high surface hardness and adhesion typical of epoxy systems.
