Belzona 4301 (Magma CR1 Hi-Build)

Chemical Resistant Repair Composite for Metal and Concrete Substrates

A chemical resistant epoxy material for rebuilding metal and concrete surfaces and protection against chemical attack

Belzona 4301 (Magma CR1 Hi-Build) is a high performance, paste-grade system with outstanding chemical resistance to a broad range of chemicals, especially concentrated inorganic acids and alkalis.

This material is designed for rebuilding or protecting metal and concrete surfaces against chemical attack. In addition, it is ideally suited to repairing damaged chemical resistant linings.

This two-component repair composite can be used to form nozzle inserts to provide further chemical protection for vessel nozzles. Furthermore, Belzona 4301 works effectively when used to profile rough surfaces prior to the application of a suitable Belzona coating.

This solvent-free material is easy to mix and apply without the need for specialist tools.

Key Benefits:

  • Excellent chemical resistance against a wide range of chemicals, especially concentrated inorganic acids and alkalis
  • Easy to mix and apply with no specialist tools
  • Reduced health and safety risks as it is solvent-free
  • Application and cure at room temperature – no hot work involved
  • No shrinkage, expansion or distortion
  • Excellent electrical insulation characteristics
