Fostering the Growth of Fastening Market

The quality of our fasteners speaks for itself

We are specializes in producing a better protective coating for steel that enhances its service life in harsh environments. It is particularly useful to industrial plants operating in hot, humid, tropical and marine atmospheres where high corrosion rates occur.

It has the following characteristics:

  • Inert to a wide range of chemicals and solvents commonly used in industries
  • Superior coating adhesion throughout its service life
  • Low coefficient of friction
  • Able to withstand severe temperature extremes, from -45°C to 232°C, without significantly affecting its properties
  • Non-wetting property which facilitate cleaning-up and ease of maintenance
  • Good resistance to chipping
  • Excellent weather resistance
The coating process involves:

  1. Thorough cleaning and chemical treatment of the steel substrate to ensure good bonding;
  2. Coating with primer;
  3. Finally applying a coat of fluorocarbon polymer.

Outstanding Features

  1. Rust and Corrosion Prevention
  2. • Outstanding coating protection due to unique coating system
    • Superior durability in corrosive environments and marine atmosphere
    • Excellent performance in outdoor hot, humid and tropical environment
  3. Heat Resistance
    • Applicable over a wide temperature range from -45°C to 232°C
  4. Weather Resistance
    • Good resistance to sunlight, rain and seawater spray
