Chemical Storage Tank Relining





May 2019


Chemical Storage Tank – Mild Steel, with external Cladding


Epo-Chem™ RS 500P, a surface and moisture tolerant epoxy MIO primer

Epo-Chem™ RA 500M moisture tolerant glass flake filled epoxy topcoat, designed for immersed applications


Sulphonic Acid Storage at 50° C


Existing epoxy lining on this chemical storage tank was in poor condition, with large sections experiencing deterioration alongside staining and corrosion of the tank wall. This stained the finish product preventing use until a long term solution was found.

Chemcote’s Solution

Set up scaffolding inside tank and utilised efficient surface preparation techniques to minimise mobilisation of blasting costs whilst still achieving an optimal surface to produce long term coating adhesion
