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.
