Properties

SMTPL engineers coatings to meet the specific needs for its industrial customers. The tabulation provides information on key coating properties and recommendation or use.

SMTPL’s Pharma-Grade coatings are a family of monolayer, multilayer, nano-layered chromium nitride, chromium and nickel alloy coatings designed to optimize for the Tablet tooling application.

SMTPL’s Pharma-Grade coatings offer good wear resistance, low coefficient of friction, chemical inertness, high oxidation thresholds as well as corrosion resistance.
