Q1: What are the primary application areas for Novoperm Yellow 4G 01?
A: Novoperm Yellow 4G 01 is widely used in high-performance industrial coatings, automotive refinish systems, and premium plastic applications—especially where excellent lightfastness, thermal stability, and clean yellow hue are required. It is also suitable for selected ink formulations demanding strong tinting strength and good dispersion behavior.
Q2: How does this pigment perform under elevated processing temperatures?
A: As a high-stability perylene-based yellow pigment, Novoperm Yellow 4G 01 exhibits good resistance to thermal degradation during standard polymer processing conditions—including injection molding and extrusion of engineering thermoplastics—making it suitable for applications requiring short-term exposure up to approximately 280 °C.
Q3: Is Novoperm Yellow 4G 01 compatible with common organic solvent-based and waterborne coating systems?
A: Yes—this pigment demonstrates good compatibility and dispersion stability in both solvent-borne systems (e.g., acrylic, polyester, and polyurethane resins) and many waterborne architectures when properly dispersed using appropriate surfactants or polymeric dispersants.
Q4: What is the typical dosage range for achieving optimal color strength and opacity?
A: Dosage depends on the specific formulation requirements and desired chroma, but it is typically used at low concentrations—generally ranging from 0.1% to 2% by weight in plastics and coatings—due to its high tinting strength and efficient particle dispersion characteristics.
Q5: Does Clariant provide recommended dispersants or grinding media for optimal pigment performance?
A: Clariant offers technical support and can recommend suitable polymeric dispersants, wetting agents, and milling protocols based on the target system—such as specific acrylate or polyurethane dispersants for coatings or functionalized PE wax carriers for polyolefin masterbatches.
