Premium coating system designed for the specific requirements of stainless steel substrates

Ceramic Polymer GmbH has developed a new premium coating system ProGuard CN-OC designed for the specific requirements of stainless steel substrates. The idea to achieved such a coating came as a result of specific customer requirements, , in which even stainless steel did not provide satisfactory corrosion protection.

They have created a unique coating product line, which fulfills highest demands by the chemical integration of special organic fillers in our multifunctional, hybrid epoxy resin base.

ProGuard CN-OC provides:

- Excellent adhesion> 30 N / mm ²

- Excellent chemical resistance against acids and alkaline solutions

- Outstanding chemical against hot corrosive vapors

- Easy application without solvents, by airless spraying methods

- Direct application no previous use of a primer necessary

The adhesion value on stainless steel is averaged 17,7 N/mm² after curing at room temperature (20°C) for 24 hours. The coating can be removed partially by shear test.

After tempering of 70°C for 1 hour the coating cannot be removed by shear test. All specimens with 70°C-tempering show cohesion fractures. For chemical testing,  PROGUARD CN-OC was exposed to highly-aggressive chemical attack non-stop for more than 9.000 hours (1 year) in different formulations 

 

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
