Lining material FRP series

Overview
HEGGEL® FRP are glass fiber reinforced lining systems for application on primed steel and concrete substrates. They provide chemically and mechanically resistant, crack‑bridging linings for storage tanks, sumps, basins, trafficked floors and other liquid‑handling structures. Systems are selected by resin base (Vinyl‑Ester, Furan, Phenolic, Epoxy) according to process and exposure conditions.

• Electrically conductive option (with hybrid mat)

HEGGEL® FRP 333
Glass‑mat reinforced furan lining providing high chemical resistance for prepared steel and cementitious substrates and over compatible rubber linings.

• Temperature resistance up to 60°C on concrete and up to 100°C (dry) on steel, depending on chemicals
• Very high resistance to inorganic/organic acids and alkalis
• High resistance to greases, oils, fuels, solvents and hydrocarbons
