Our newest coating! A durable, inert, corrosion resistant coating that is harder than steel and highly resistant to acid and base attack. Ideal for valves and components that require a tough scratch resistant coating. Dursan is a hydrophobic surface that strongly repels water.
The ultimate in inert coating technology. Eliminate surface interaction in process, analytical, oil and gas sampling. Allow for fast accurate sampling the first time, every time. Improves test efficiency while reducing overall sampling/analytical cost.
A corrosion resistant coating that increases the lifetime of system components. Improve the corrosion performance of stainless steel, eliminate the use of costly high performance alloys while reducing component corrosion.
A non-stick coating designed to reduce the onset of carbon coking and fouling on stainless steel. Extend maintenance cycles in refining and petrochemical operations, improve engine and fuel delivery performance by reducing carbon build-up on fuel injectors and combustion surfaces.
A low outgassing, rapid pump down, high purity coating designed to improve ultra high vacuum system performance. Reduce vacuum pump-down cycle time, improve product yield by eliminating surface impurities.
