A durable, 2-part epoxy barrier coating optimised for resistance to hot inorganic acids such as sulphuric and hydrochloric acid up to 90°C (194°F). This solvent-free coating isolates concrete and metal surfaces from deteriorating chemical environments.
Belzona 4341 (Magma CR4) provides a safe and hygienic surface which meets the USDA requirements for incidental food contact. It is easy to mix and apply without the need of specialist tools and cures at room temperature.
