Fosroc Lokfix E55S

Fosroc Lokfix E55S is a medium to heavy duty resin anchoring solution with a significantly broader approval envelope than the polyester-based E35S. Its vinyl-ester formulation delivers higher compressive strength (100 MPa) and an elevated E modulus (14,000 MPa), making it suitable for more demanding structural applications including post-installed reinforcement and fixings in seismic zones. Like all Lokfix products, it does not apply expansive force to the substrate, allowing closer edge distances than mechanical anchors.

Typical applications include

• Anchoring threaded rods into cracked and uncracked concrete (M8–M30)
• Post-installed reinforcement (Ø8–Ø32)
• Fixings in seismic zones (C1)
• Fire-rated applications up to 2 hours
• Internal, external and submerged installations
• Masonry anchoring using Hollow Block Sleeves (M8–M12)
• Horizontal, vertical and overhead application

Benefits

• Styrene-free vinyl-ester resin, low VOC, LEED compliant
• Approved for cracked and uncracked concrete — ETA-18/0586
• Post-installed rebar approved — ETA-18/0587 (Ø8–Ø32)
• Masonry approved — ETA-18/0585 (M8–M12)
• C1 seismic resistance
• Fire resistance up to 2 hours (consult test data for specific conditions)
• Suitable for dry, damp and flooded concrete
• Internal, external and submerged conditions
• No expansive force allows closer edge distances than mechanical anchors
• Protects fixing from corrosion
• Re-usable cartridge, use a standard skeleton gun

Good to know

• Curing times vary with substrate temperature, from 6 minutes gel time and 45 minutes fixing time at +20°C, down to 90 minutes gel time and 1,440 minutes fixing time at -10°C.
• Do not load or apply tension to the fixing until the stated fixing time has been observed.
• Compressive strength: 100 MPa / E modulus: 14,000 MPa
• Permanent service temperature: -40°C to +72°C
• 45 minutes fixing time at +20°C
