Project: Acid Storage Tank

Location: Philippines

Applicator: In-house contractor

Date of Application: September 1999

 

 

 

The Challenge:


The client is looking for an alternative acid proof tank lining since the recommended system is very expensive. The coating should comply with the current environmental regulations and safe to use inside confined spaces. It should resist aggressive chemicals such as a mixture of hydrochloric and hydrofluoric acids and provide long-term protection.

 

 

The Recommendation:


Corro-Dur is the ideal choice for acid proof tank lining as per evaluation by the client since this product is 100 % solids, solvent-free and odorless formulation provides worker safety and the ability to seal cracks (because wet film thickness equal dry film thickness. The addition of Kevlar fibers on Corro-Dur 258 makes it a tough, durable, chemical resistant micro-fiber reinforced epoxy that adheres much better than other epoxies to wet, damp and underwater surfaces. Corro-Dur 255 is formulated with novalac epoxy, which makes it highly resistant to many acids of different concentrations. The surface was abrasive blasted and apply Corro-Dur 258 at a minimum dry film thickness of 250 microns while Corro-Dur 255 was applied as topcoat at a minimum of dry film thickness 300 microns.
