Q1: What is the primary pigment chemistry and classification of this color paste?
A: Yingcai Chroma-chem 844 is a high-performance phthalocyanine green pigment (Pigment Green 7) dispersed in a non-aqueous, solvent-based vehicle system. It belongs to the copper phthalocyanine derivative family and is classified as an organic green pigment with excellent lightfastness, thermal stability, and chemical resistance.
Q2: Is this color paste suitable for use in coatings requiring high weather resistance?
A: Yes — Chroma-chem 844 is specifically engineered for demanding outdoor applications. Its phthalocyanine green base offers outstanding UV stability and resistance to chalking, making it well-suited for architectural coatings, industrial maintenance paints, and automotive refinish systems where long-term color retention is critical.
Q3: How should this paste be incorporated into solvent-borne resin systems?
A: The paste is designed for easy integration into standard solvent-borne acrylics, alkyds, polyurethanes, and epoxy resins. Pre-mixing with a portion of the carrier solvent followed by high-shear dispersion ensures optimal deagglomeration and uniform distribution. Avoid prolonged high-temperature processing above 80 °C to preserve dispersion integrity.
Q4: Can this product be used in food-contact or pharmaceutical packaging inks?
A: No — Chroma-chem 844 is not certified for direct food-contact applications. It is formulated for general industrial and decorative uses. For regulated packaging applications, please consult Yingcai’s dedicated food-safe pigment portfolio and request applicable regulatory documentation separately.
