UNIQUE POLYMER SYSTEMS specialises in delivering robust protective solutions for industrial environments. This case study details the successful protection of a chemical bund at a U.S. manufacturing site using UPS 804 ECPR EPOXY CONCRETE PATCH REPAIR, UPS 909 PP POROUS PRIMER and UPS 407 EN EPOXY NOVOLAC.

A U.S. manufacturing site faced the challenge of protecting its chemical bunds from the aggressive effects of up to 98% concentrated sulphuric acid. The bunds had suffered damage over time, exposing both the concrete and steel surfaces to potential corrosion and chemical degradation.

The challenge was to repair the damaged concrete and steel surfaces and apply a protective coating system that would provide long-lasting resistance to concentrated sulphuric acid. The solution needed to ensure that the bunds could withstand the harsh chemical environment and prevent future damage.

UNIQUE POLYMER SYSTEMS provided a comprehensive repair and protection solution using UPS 804 ECPR, UPS 909 PP, and UPS 407 EN. The application process involved the following steps:

Surface Preparation

- All loose and damaged concrete was removed using hand tools. The lost material was then replaced with UPS 804 ECPR which restored the integrity of the bunds.

Priming with UPS 909 PP POROUS PRIMER

- All concrete and porous surfaces were primed with UPS 909 PP. For additional protection, drains and outlets were reinforced with a layer of glass fiber incorporated into the wet primer, ensuring a solid base for the final coating.

Steel Surface Preparation

- Steel substrates were prepared using the UPS MINI-BLASTER to create a suitable Sa 2.5 surface profile, ensuring proper adhesion of the protective coating. 

Application of UPS 407 EN EPOXY NOVOLAC

- All surfaces were coated with two applications of UPS 407 EN, achieving a total dry film thickness of 800 microns. This dual-coat system provided robust protection against the corrosive effects of concentrated sulphuric acid.

The application of UPS 804 ECPR, UPS 909 PP, and UPS 407 EN successfully protected the chemical bunds from potential sulphuric acid spills. The durable coating system restored the bunds' integrity and ensured long-term resistance to chemical exposure, safeguarding the manufacturing site's infrastructure.

This case study highlights the effectiveness of UNIQUE POLYMER SYSTEMS' protective coatings in maintaining and extending the life of industrial chemical containment areas. Our advanced materials and precise application techniques delivered a reliable solution that ensured the long-term durability of the chemical bunds.
