  1. High anti-corrosion performance Salt Spray Test 2000 Hours. Combined Cycle Test 200 Cycles. (High anti-corrosion type) Also applicable for SUS. *Except for high anti-corrosion type, all the other treatments standard: SST 1000 Hours, CCT 100 Cycles.
  2. Free from hydrogen embrittlement especially perfect performance on the surface of high carbon steel Pickling and electrolytic processes are not necessary, which can eliminate the hydrogen embrittlement problem. DISGO treatment is especially developed for the high tensile strength carbon steel (CRMO or HTSS).
  3. Environmental-friendly Free from the hazardous substances such as hexavalent chromium, trivalent chromium, lead, cadmium, mercury. RoHS and REACH compliant.
  1. Reducing the electrolytic corrosion Reducing dissimilar metal contact corrosion apparently between the products and aluminium board or plated steel board.
  2. Low cure temperature The baking temperature below 200 C no effect on the physical properties of products. Applicable for the carbon steel springs and screws.
  3. Controllable coefficient of friction Three types in total, low coefficient of friction type normal coefficient of friction type and high coefficient of friction.
  4. Chemical and heat resistance
