Fosroc Lokfix E55S Vinyl Ester Chemical Anchor

Fosroc Lokfix E55S Vinyl Ester Chemical Anchor

Styrene free vinyl-ester resin based cartridge system, for anchoring reinforcement, fixings in to a variety of substrates.

Description:

Fosroc Lokfix E55S is a styrene-free vinyl-ester resin anchoring system designed for superior performance in concrete, masonry, and a wide range of substrates. This advanced cartridge-based anchoring solution is ideal for structural reinforcement, threaded rod fixings, and post-installed rebar connections where high strength, chemical resistance, and durability are essential.

Engineered for reliability in both dry and wet environments, Fosroc Lokfix E55S delivers excellent bonding power even under extreme conditions — including cracked concrete, submerged installations, and seismic loading zones. Its rapid curing and fire-rated properties make it a professional-grade choice for engineers and contractors across commercial, industrial, and infrastructure projects.

Key Features & Advantages

• Styrene-free formulation – low VOC and eco-friendly.

• High bond strength suitable for heavy-duty anchoring.

• Fast curing and early load capability for rapid project completion.

• Fire resistance up to 120 minutes (Fosroc Lokfix E55S only).

• C1 seismic resistance – tested and approved.

• Useable with standard skeleton gun (300ml cartridge).

• No expansive pressure – ideal for close-edge fixings.

• Waterproof and corrosion-resistant.

• Usable in dry, damp, and flooded conditions.

• Applicable horizontally, vertically, and overhead.

• Reusable cartridge system – simply replace the static mixer.

• Complies with ETA and EAD international standards.

Typical Applications

Fosroc Lokfix E55S is widely used in:

• Fixing post-installed reinforcement bars (rebar).

• Anchoring threaded rods, bolts, and internal sleeves.

• Bonding and crack sealing on concrete surfaces.

• Submerged installations in marine or water-retaining structures.

• Structural anchoring in bridges, tunnels, and high-rise buildings.

• Suitable for solid and hollow masonry, porous concrete, and lightweight blocks.

This product is perfect for both new construction and repair/retrofit projects where structural integrity and chemical durability are required.

Technical Data

Curing Time (at 20°C)

• Gel Time: 6 minutes

• Curing Time (Dry Conditions): 45 minutes

• In damp or wet conditions, curing time may approximately double.

• Optimal cartridge temperature: +15°C to +30°C.

For lower temperatures (-20°C to +15°C), use Fosroc Lokfix E55L, a low-temperature variant (without seismic/fire rating).

Design & Installation Guidance

Drilling & Hole Preparation

1. Drill the hole to the required diameter and depth using a percussion drill.

2. Clean thoroughly using a wire brush and compressed air (4x blow, 4x brush, 4x blow).

3. Ensure the hole is dry and dust-free before application.

Application Procedure

1. Attach the static mixer nozzle to the cartridge.

2. Insert into a standard 300ml gun.

3. Dispense until the resin color is uniform (discard initial material).

4. Fill the hole from the back, avoiding air gaps (approx. ¾ full).

5. Insert the fixing bar or rod slowly using a twisting motion.

6. Allow full curing time before loading.

Note:
Do not over-torque bolts. Follow the recommended torque limits provided in design tables for uncracked concrete. For re-use, remove the used mixer and re-cap the cartridge.

Design Standards and Approvals

• ETA-18/0587, ETA-18/0586, ETA-18/0585 – Certified performance and safety.

• EAD 330499-00-0601 – Post-installed rebar and cracked/uncracked concrete.

• EAD 330076-00-0604 – Anchoring in masonry.

• ETAG 001 TR 023 & TR 029 – Superseded, fully compliant.

• LEED and low VOC (A+) – Environmentally friendly and sustainable.

Packaging & Yield

• Supplied in 300 ml cartridges, 12 cartridges per box.

• Each cartridge includes one static mixer nozzle.

• Accessories available:

  • Extension nozzles

  • Hollow block sleeves

  • Piston plugs

  • Steel cleaning brushes

  • Dust blower pumps

  • Hand applicator guns

Yield Estimation Formula:

Consumption (ml)=(πrhole2−πrbolt2)×Hole Length (cm)text{Consumption (ml)} = (pi r_text{hole}^2 – pi r_text{bolt}^2) times text{Hole Length (cm)}Consumption (ml)=(πrhole2​−πrbolt2​)×Hole Length (cm)

Always include allowances for extrusion, waste, and over-drilling.

Storage and Shelf Life

• Shelf Life: 12 months (unopened)

• Storage Conditions: +5°C to +25°C, in a dry warehouse.

• Protect from direct sunlight and frost.

Health & Safety

• Read and follow the Safety Data Sheet (SDS).

• Avoid contact with skin and eyes.

• Use protective gloves and eyewear.

• Ensure adequate ventilation during application.

• Clean uncured material with Nitoflor Sol immediately after use.
