Containment-Grade Coating Provides Enhanced Flexibility
Belzona 5815, a solvent-free containment-grade coating with enhanced flexibility, is designed to protect concrete chemical containment areas and bunds.
Belzona (Miami, Florida), a leading designer and manufacturer of polymer repair composites and industrial protective coatings, has introduced a new containment-grade coatings for the protection of concrete containment areas.
Concrete is often used to build secondary chemical containment areas and bunds, which retain spilled chemicals, facilitate product recovery and prevent environmental contamination, as required by environmental and safety regulations. However, concrete walls and floors are prone to damages caused by cracking, increased porosity, reinforcing bar corrosion and chemical attack.
Protective coatings for these areas provide chemical resistance to aggressive chemicals. For this purpose, Belzona has launched Belzona 5815, a solvent-free containment grade coating with enhanced flexibility.
Belzona 5815 has reportedly undergone testing to demonstrate that the product can resist a range of dilute acids, alkalis, fuels and oils. Moreover, “it can bridge cracks in concrete up to an extent” and “has great adhesion to nonmetallic and metallic substrates”, says Osmay Oharriz, technical manager at Belzona.
According to the company, testing also shows that Belzona 5815 has high tensile and flexural strength; it can reportedly resist pressure up to 2,430 psi after it has been cured at 72 °F (22 °C) for seven days, enabling it to bridge cracks. Additionally, it is temperature resistant, enduring temperatures up to 320 °F (160 °C). For many applications, the product is suitable at temperatures down to -40 °F (-40 °C). In addition, Belzona 5815 is said to be easy to mix and apply, and no surface conditioner is required. Belzona 5815 can be applied by brush, roller, squeegee or an airless spray system for large containment areas.
