Clariant Hostaperm Violet RL 02 Pigment – Frequently Asked Questions (FAQ)

Q1: What is the primary chemical class and pigment type of Hostaperm Violet RL 02?

A: Hostaperm Violet RL 02 is a high-performance quinacridone-based organic pigment, classified under the Pigment Violet 19 (PV19) family. It exhibits excellent crystalline stability and is engineered for demanding coloristic and durability requirements in industrial applications.

Q2: Is this pigment suitable for use in food-contact plastics or packaging applications?

A: Hostaperm Violet RL 02 is not approved for direct food-contact applications under major global regulatory frameworks. It is intended for non-food-contact industrial uses such as automotive coatings, industrial paints, and engineering plastics where high lightfastness and thermal stability are required.

Q3: What is the typical dosage range when incorporating this pigment into polymer systems?

A: Dosage depends on the specific polymer matrix, desired shade strength, and processing conditions, but it is generally used at low concentrations—typically ranging from 0.1% to 2% by weight—to achieve optimal dispersion, color development, and cost-efficiency without compromising mechanical properties.

Q4: How does Hostaperm Violet RL 02 perform under elevated temperature during melt processing?

A: This pigment demonstrates good thermal stability and retains its coloristic integrity during standard polymer processing operations, including extrusion and injection molding up to approximately 280°C. Its performance remains consistent across common thermoplastics such as polyolefins and engineering resins when properly dispersed.

Q5: Can Hostaperm Violet RL 02 be used in aqueous coating systems?

A: While primarily optimized for solvent-based and high-solids systems, it can be formulated into aqueous dispersions with appropriate surfactants and stabilization technology. However, performance—especially in terms of gloss, rheology, and long-term storage stability—requires careful formulation optimization and compatibility testing.
