Q1: What is the primary chemical composition of Cathay CATHAYCOAT Yellow YC22B?
A: Cathay CATHAYCOAT Yellow YC22B is a high-performance inorganic yellow pigment based on modified iron oxide and/or complex metal oxides, engineered for enhanced thermal stability and lightfastness in demanding industrial applications.
Q2: Is YC22B suitable for use in heat-sensitive polymer systems such as polyolefins or PVC?
A: Yes — YC22B is specifically formulated for excellent thermal stability and can withstand processing temperatures commonly encountered in polyolefin extrusion, injection molding, and rigid PVC calendering without significant color shift or decomposition.
Q3: How does YC22B compare to organic yellow pigments in terms of weather resistance?
A: As an inorganic pigment, YC22B offers significantly superior UV resistance, chalking resistance, and long-term color retention compared to most organic yellows—making it well-suited for exterior coatings, architectural paints, and outdoor plastic applications.
Q4: Can YC22B be dispersed effectively in water-based systems?
A: Yes — with appropriate surfactant selection and standard dispersion techniques (e.g., high-speed stirring or bead milling), YC22B achieves stable and uniform dispersion in aqueous paint, ink, and coating formulations.
Q5: What is the typical dosage range for YC22B in industrial coatings and plastics?
A: Dosage depends on the desired shade strength and application requirements, but YC22B is generally used at low concentrations — typically ranging from 0.1% to 2% by weight in plastics and 2% to 8% by volume solids in architectural and industrial coatings.
