  YELLOW IRON OXIDE (PY42) PRODUCT RECOMMENDED PIGMENTS
  • Nubifer Y-2000 series – The very basic series Yellow Iron Oxide pigment. Recommended for plastics; only low temperature such as PVC, EVA, LDPE and rubber, and coatings where high dispersibility is not requested and for general use in cement and concrete applications.
  • Nubifer Y-4000 series - The basic series of Yellow Iron Oxide pigment. Recommended for plastics, coatings, cement and concrete applications.
  • Nubifer Y-5000 series – Micronized/high dispersibility/narrow colorimetric tolerance Yellow Iron Oxides
    o Nubifer Y-5010 – Light shade Yellow Iron Oxide
    o Nubifer Y-5020 – Reddish shade Yellow Iron Oxide
    o Nubifer Y-5028 – Reddish shade Yellow Iron Oxide with  enhanced rheological performance
  • Nubifer Y-7000 series – Micronized, high heat fastness Yellow Iron Oxides
    o Nubifer Y-7050 – Encapsulated grade Yellow Iron Oxide. Recommended for high temperature curing coatings (heat fastness = 260°C, 5 min.), for medium processing temperature resins (heat fastness = 260°C, 5 min.) and PVC; more suitable for unplasticized PVC compounds than conventional Yellow Iron Oxides.

VALUE ADDED SERVICES

Advanced Color Matching

Ferro technicians combine their talents with today's most advanced computer color analysis equipment to offer our customers precise color-matching services. Our spectrophotometry process minimizes metamerism, speeds up color matching, ensures consistent quality and helps identify the pigment combination that produces any given color for the lowest possible cost and right performance characteristics, including outdoor durability and NIR reflectance.

Ferro can match your color chip/drawdown or we can refer to complete files of OSHA, Munsel, RAL, Federal Standard 595 Series or Pantone® matching systems to achieve your reference number. All of our colors are matched to Ferro standards or your reference sample, ensuring precise color reproduction from order to order.

Providing Formulation Guides/Assistance with Startup Formula Creation

We assist customers in their product development efforts to ensure regulatory compliance (e.g., usage in food, cosmetics) and desired performance including anticorrosion, outdoor durability and NIR reflectance.
