Q1: What are the primary application areas for Clariant HL70?
A: Clariant HL70 is widely used in high-performance industrial coatings, automotive refinish systems, and plastic coloration—particularly where excellent heat stability, lightfastness, and gloss retention are required. It is also suitable for select ink formulations demanding strong tinting strength and dispersion stability.
Q2: How does HL70 perform under elevated processing temperatures?
A: HL70 exhibits good thermal stability, making it suitable for standard melt-processing conditions in thermoplastics such as polyolefins and engineering resins. Performance remains robust up to typical extrusion and injection molding temperatures, though optimal results depend on residence time and shear profile.
Q3: Is HL70 compatible with common dispersing agents and resin systems?
A: Yes—HL70 demonstrates broad compatibility with conventional polymeric dispersants, acrylic and polyester-based binder systems, and solvent-borne as well as water-reducible coating media. Successful integration typically requires optimized wetting and dispersion protocols during formulation.
Q4: What is the typical dosage range when using HL70 in plastics and coatings?
A: Dosage depends on the desired shade depth and substrate requirements, but HL70 is generally used at low concentrations—typically ranging from 0.1% to 2% by weight in plastics and 0.5% to 3% in liquid coatings—due to its high tinctorial strength and efficient pigment utilization.
