Platinum Coating

The synergy effect of the mechanical characteristics of refractory material and the corrosion resistance of platinum contributes to the effective operation of production lines.

Platinum or platinum alloy is sprayed onto the surface of a refractory material to form a platinum or platinum alloy coating. This provides dramatically improved glass corrosion resistance of the refractory material, making it possible to more effectively manufacture glass with a smaller amount of precious metals, compared with conventional platinum materials.

ACTTM(Advanced Coating Technology)

ACTTM processing technology, acquired from Johnson Matthey P.L.C., offers the combined advantages of refractory material that is resilient to high temperature deformation and platinum metal that exhibits a high temperature corrosion resistance.

  • Dramatically prolonged service life of equipment with reduced glass erosion and wear
  • The amount of platinum used can be reduced to one-half to one-fourth of that with conventional platinum lined products, enabling considerable cost savings.
  • The coating functions as a heater when an electrical current is applied.
