01. The Challenge :
The wastewater tanks at Pengerang Deepwater Terminal 2 (PDT2) required a high performance coating system in order to protect these structures from harsh chemicals & high salt content solutions. Besides that, any tanks that will potentially use a biological wastewater treatment process will also require a coating system that does not harm any microorganisms, eliminating the usage of any conventional coal tar epoxy coating systems.




02. PROPOSED Solution :
Dritech Chemicals has supplied a high performance coating solution to protect 55,000 sqft. of structures at Petronas RAPID, Pengerang.
Dri-Gard TZ 300GF is a two-part, solvent free epoxy protective coating that functions as both a primer and base coat, while Dri-Gard EP 1800 is a high performance, chemical resistant epoxy novolac coating. Epoxy novolac is famous for its high chemical resistance, and is able to protect structures against against extremely harsh chemicals such as 98% sulphuric acid.
The Dri-Gard coating system was also fiber-reinforced to ensure long-term durability, preventing unwanted downtime for repair and maintenance.
With its excellent abrasion resistance & adhesion strength to concrete, the Dri-Gard system used in this project was extremely suitable to be used for various types of wastewater tanks.
03. FINAL OUTCOME :
The installation of the Dri-Gard coating system for this project was completed via spray application – allowing the project to be completed within the time frame required. The final result is a seamless, high performance protective coating system with excellent resistance against chemicals and salt solutions without harming any biological material in the tanks required for the treatment process.

- high chemical- & salt-resistant coating system
- Spray-applied coating system for fast installation
- Reinforced with Super Fibre R100 for long-term durability & reduced downtime for maintenance/repairs
- non-toxic epoxy-based coating system for biological wastewater treatment processes
