Q1: What is the primary application field for Novoperm Yellow HR 70?
A: Novoperm Yellow HR 70 is primarily used in high-performance industrial coatings, automotive refinish systems, and premium plastics applications where excellent heat stability, lightfastness, and weather resistance are required.
Q2: Is this pigment suitable for use in food-contact plastics?
A: Novoperm Yellow HR 70 is not specifically designed or certified for direct food-contact applications. Its use in food packaging or containers requires thorough regulatory review and approval by relevant authorities based on the final formulation and processing conditions.
Q3: How does Novoperm Yellow HR 70 compare to other yellow pigments in terms of thermal stability?
A: This pigment exhibits superior thermal stability compared to many conventional monoazo yellows, enabling its use in demanding plastic processing operations such as injection molding and extrusion without significant color shift or degradation.
Q4: What dispersion methods are recommended for optimal performance in coatings?
A: For best results in solvent- and water-based coating systems, high-shear dispersion using appropriate dispersing agents and milling equipment is recommended. Pre-dispersed paste or liquid concentrates may also be used to enhance consistency and reduce processing time.
Q5: Can Novoperm Yellow HR 70 be used in combination with other organic pigments?
A: Yes — it demonstrates good compatibility with a broad range of organic pigments and common inorganic pigments, supporting versatile shade development and enhanced chromatic performance in multi-pigment formulations.
