Q1: What is the primary chemical composition of Cathay CATHAYCOAT Red RC18?
A: Cathay CATHAYCOAT Red RC18 is an inorganic iron-based red pigment, formulated as a stabilized iron oxide complex with enhanced thermal and chemical resistance. Its composition is optimized for consistent hue, opacity, and durability in demanding industrial coatings.
Q2: Is RC18 suitable for high-temperature curing applications?
A: Yes — RC18 exhibits excellent thermal stability and is routinely used in coating systems cured at temperatures up to 250 °C, including coil coatings, powder coatings, and engine-applied finishes. It maintains color integrity without charring or significant hue shift under standard industrial bake cycles.
Q3: How does RC18 perform in acidic or alkaline environments?
A: RC18 demonstrates good resistance to both mild acidic and alkaline conditions typical of industrial pretreatment and cleaning stages. However, prolonged exposure to strong mineral acids or highly caustic media may affect surface stability; compatibility should be verified within the final formulated system.
Q4: Can RC18 be used in waterborne coating systems?
A: Yes — RC18 is compatible with a broad range of waterborne acrylic, epoxy, and hybrid resin systems. Proper dispersion using conventional wetting agents and high-shear mixing is recommended to ensure optimal color development and suspension stability.
