RL 500PF for Castor Segments

Industry                      

Steel Manufacturing

 

Date

September 2012 – 2016

 

Substrate

Aged Carbon Steel

 

Product 

Epo-chem™ RL 500PF – a surface/moisture tolerant zinc rich epoxy coating resistant to 150°C which can also be applied on hot surfaces.

 

Environment 

Quenching station – Steam with radiating heat at 130°C

 

Challenge

These segments are subjected to extreme conditions as part of the steel casting process. Upon inspection, we found severe paint breakdown and asset deterioration. This was due to previously applied coatings incapable of resisting the high temperatures. Premature corrosion was also found during inspection.

 

Chemco’s Solution     

We recommended 2 coats of Epo-chem™ RL 500PF. This coating system is known to provide excellent long term corrosion resistance for this type of environment.

 

Scope                         

Abrasive blasting to AS 1627.4

Application of 2 coats of RL 500PF @ 300µm

 

Results 

The client welcomed a trial in an effort to reduce long term maintenance costs. He found this was possible using the Chemco anti corrosion coating system. After equivalent time in service our zinc rich high temperature resistant epoxy coating system was showing no signs of failure whatsoever. A long term corrosion protection was achieved. All segments are now specified with this Chemco system
