Protective Coatings and Bund Linings For Chemical Containment

epoxy linings for chemical containment

The requirements for protective coatings and bund linings for chemical containment are very demanding. Government agencies, concerned corporations and individuals all demand that systems are in place to safeguard their assets and our environment from chemicals and toxic substances.

Epoxy linings for chemical containment are generally used for the construction of tanks, bunds, and secondary containment areas. Unlike rubber liners, which can be laid up and hand rolled into place, epoxy resin is applied in a liquid state and then steam cured into a monolithic system. This process allows the lining to be installed in a much faster timeframe, and it can be applied in very cold and damp conditions.

Sealing the Deal: The Comprehensive Guide to Epoxy Linings for Chemical Containment

When the lining is applied it forms an almost impenetrable ‘physical barrier’ at its surface, which is extremely effective against many types of corrosion and chemical attack. In addition, the ‘cross-linking’ nature of the epoxy resin and hardener reaction produces an almost impenetrable mechanical ‘clamping’ effect at its surface.

Two-part epoxies are very common and widely available from big box stores, with J-B Weld products dominating the market. They are available in a variety of different kits from simple tubes which require manual mixing to cartridges for specialized guns. They are commonly used for fastening countertops to substrates, and also in building projects for attaching concrete elements to others either of concrete or of stone or metal. They can also be used to seal and bed down surfaces of concrete walls and floors in a chemical-resistant fashion, particularly for sealing cracks where water, oil, diesel and other chemicals have leaked through or under the existing lining.
