UNIQUE POLYMER SYSTEMS provides advanced protective solutions for industrial environments. This case study details the successful protection of structural steelwork at a chemical processing plant using UPS 405 EPC-XL EPOXY PROTECTIVE COATING - EXTENDED LIFE and UPS 509 UVST UV STABLE TOPCOAT.

The structural steelwork at a chemical processing plant was experiencing significant corrosion due to exposure to ammonium sulphate. This chemical attack had severely compromised the steel's integrity, leading to the need for replacement in some areas. To prevent further degradation and protect the steel, a robust coating system was required.

The primary challenge was to apply a protective coating that could withstand the corrosive effects of ammonium sulphate and provide long-term durability. The solution needed to be applicable to both the existing steelwork and the new replacement sections, ensuring comprehensive protection across the site.

UNIQUE POLYMER SYSTEMS provided a comprehensive protection solution using UPS 405 EPC-XL and UPS 509 UVST. The application process involved the following steps:

Surface Preparation

- In-situ steel work was prepared using mechanical hand tools to remove any loose material and create a suitable surface for coating.

- New sections of steel were abrasive blast cleaned to SA2.5 with a 75-micron profile to ensure optimal adhesion of the coating.

Application of UPS 405 EPC-XL EPOXY PROTECTIVE COATING – EXTENDED LIFE

- UPS 405 EPC-XL was applied using a single-leg airless spray, with brush and roller used where necessary. The coating was applied to a total nominal dry film thickness of 500microns, providing robust protection against chemical attack.

Application of UPS 509 UVST UV STABLE TOPCOAT

- Once the epoxy coating was cured, the steelwork was over coated with UPS 509 UVST. This final layer was applied by spray, brush, or roller, providing additional protection and ensuring UV stability for the long-term durability of the coating system.

The application of UPS 405 EPC-XL and UPS 509 UVST successfully protected the structural steelwork from the corrosive effects of ammonium sulphate. The coating system provided a durable barrier that restored the integrity of the steelwork and ensured its continued performance in the challenging environment of the chemical processing plant.

This case study demonstrates the effectiveness of UNIQUE POLYMER SYSTEMS' protective coatings in safeguarding industrial infrastructure from chemical corrosion. Our advanced materials and precise application techniques delivered a reliable solution that ensured the long-term durability and safety of the structural steelwork.
