Pigment Classes:Pigment Yellow119/ Color Index No. 77496
J.K chemical 321T is a light tan ferrite, produced by the high temperature reaction of iron oxide and zinc oxide(Fe2O3•ZnO).321T is a high performance, heat stable pigment, micronized for ease of dispersion, color consistency and stable resistance and weather durability is required.
performance in coatings, both aqueous and non‐aqueous, plastics and other high‐heat applications where high temperature.
The 321T is most commonly used in plastics. High temperature stability and ease of dispersion make these pigments suitable for resin systems from LLDPE and vinyl to sophisticated engineering polymers and silicone rubber compounds. Interactions of pigment and some resins in high‐temp plastics compounding can lead to slight color shifts. Suitability of tan pigments should be verified for specific applications. Exterior durability is improved by the ultraviolet screening properties contributed by these pigments, especially with polymers that are sensitive to sunlight.
The 321T product line is characterized as providing advantages in the following areas:
The 321T of heat stable pigments are inert, insoluble in organic materials as well as resistant against chemicals, alkali and dilute acids. 3 is of sufficient purity for use in selected applications for packaging or articles that come in contact with food(21CFR).
Uses: coil coatings, high‐bake industrialfinishes, roofing granules and plastics.
