Dye Intermediates

Since inception of the company in 1967, our manufacturing strategy has been based on efficiency through vertical integration.

To support the production of dyes the company has actively engaged in manufacturing core dye intermediates. Almost 60 % of the dye intermediates used for the production of our dyes are made in-house.

This strategy potentially offers:

  • Better streamlined manufacturing process
  • Control in transaction costs
  • Improved Quality Control
  • Improved capability to handle upside in demand
  • Enhances  the ability to secure supplies and future orders
