Q1: What is the primary chemical composition of Cathay CATHAYCOAT Red RA18?
A: Cathay CATHAYCOAT Red RA18 is an iron oxide-based inorganic pigment, formulated to deliver high thermal stability and strong chromatic performance in demanding industrial applications.
Q2: Is this pigment suitable for high-temperature coating systems?
A: Yes — RA18 exhibits excellent heat resistance and retains color integrity in curing processes up to approximately 600°C, making it well-suited for coil coatings, ceramic glazes, and high-bake industrial finishes.
Q3: How does RA18 perform in UV-exposed outdoor applications?
A: As a fully inorganic oxide pigment, RA18 offers outstanding UV stability and weatherfastness, with minimal fading or chalking observed under prolonged sunlight exposure in properly formulated protective coatings.
Q4: Can RA18 be used in waterborne coating systems?
A: Yes — RA18 is compatible with both solvent-based and waterborne systems when appropriately dispersed. Stable performance is achieved using standard dispersants designed for inorganic pigments in aqueous media.
Q5: What is the typical dosage range for optimal color development?
A: Dosage depends on formulation requirements and desired opacity, but RA18 is typically used at low concentrations — generally ranging from 0.1% to 2% by weight in finished coating systems.
