Application date
September 2020
Scope of work
Internal and external application of suitable coating systems to protect 2 diesel storage tanks in accordance with PUK specification systems 2a and 7a.
We have over 40 years of experience protecting tanks and process vessels from chemical attack.
Coating system
- Grit blast of internals to ISO 8501-1 SA 2½.
- Polyglass VEF applied via airless spray to the minimum DFT of 1250 microns, with relative humidity <85%.
- Spark test followed adequate cure of coating. Thickness test also carried out.
- Abrasive blasted internal and external surfaces with new abrasive in accordance with ISO 8501-1 to Sa2 surface finish, to achieve minimum profile surface of 50 micron
- Two coats of Plasmet ZF and a single coat of Corrothane AP1 applied.
Products
Internals: Polyglass VEF
Externals: Plasmet ZF
Top coat: Corrothane AP1
Substrate
Carbon Steel
Coating Credentials
Polygass VEF is a glass flake ester acrylic co-polymer, which performs excellently in immersed
environments. It also has excellent resistance to
solvents, acids and de-mineralised water, and great
flexibility, undercutting resistance and sliding
abrasion resistance.
Plasmet ZF is an epoxy compound incorporating rust converter, inhibitor and passivator, with leafing
barrier protection. Plasmet ZF is used as a surface
tolerant coating, formulated to give good protection
on rusted surfaces. It is also used as a high quality
primer on blast cleaned steel surfaces.
