Innovative coating product for stainless steel

Ceramic Polymer GmbH has developed the new premium coating system Proguard CN-OC, which is designed especially for high requirements on stainless steel substrates. The idea to formulate such a specific coating was formed by a multitude of explicit customer requests, in which even stainless steel did not provide satisfactory corrosion protection.

Chemical resistance tests

Proguard CN-OC was exposed to highly-aggressive chemical attack non-stop for more than 9.000 hours (1 year) in different formulations. In these test series various curing variants were explored (room temperature and room temperature plus diverse steps of tempering). The chemical resistance was tested in an extremely aggressive liquid (killer-solution), which contained 3 fluids of each 33,3% volume-mixture with a permanent temperature of 50°C:

98% H2SO4 sulfuric acid + 100% methanol + 3% sodium chloride solution

Extra tests according to customer requests were performed with excellent results, e. g. sole 98% H2SO4 sulfuric acid at 50°C and 60°C, also diverse warm and hot acid-mixtures.

Proguard CN-OC provides:
 

• Extreme adhesion > 30 N/mm²

• Excellent chemical resistance against acids and alkaline solutions

• Excellent chemical resistance against hot, corrosive gases

• Easy and solvent-free application by airless spraying methods

• Direct application, no previous use of a primer necessary

• Adequate and acceptable pot life and curing times
