Benefits, Advantages and Features Greater productivity: Anchors in dry, damp, wet or flooded holes no weather delays Fast 3 hour cure time (REO502J) Short embeddment to achieve bar yield stress Greater security: Exceeds steel strength up to AISI 316 Stainless Steel at recommended embedments High loads in shallow holes in thin slabs Versatile pure epoxy: Anchors in dry, damp, wet and flooded Oversized holes into 2.25xd b Anchors in carbide drilled and diamond cored holes For tropical and temperate climates Easy flow version for easy cold dispensing (REO502 EF) Greater safety: Low odour Non-flammable for transport and storage VOC Compliant Australian Made Installation PERFORMANCE RELATED (New Zealand refer to Epcon C6) INSTALLATION RELATED Principal Applications Reinforcing bars Deformed bars Starter bars Anchoring structural steel to concrete Anchoring stadium seating Installation temperature limits: REO502 Substrate: 5 C to 40 C. Adhesive: 20 C to 40 C. Adhesive: 5 C to 40 C. Load should not be applied to anchor until the chemical has sufficiently cured as specified. Service temperature limits: -40 C to 80 C. REO502 EF Substrate: 5 C to 30 C. Setting Times Reo 502 Working Time Cure Time (mins) (hrs) Reo 502 EF Working Time Cure Time (mins) (hrs) Drill recommended diameter and depth hole. 2. Important: Use Ramset Dustless Drilling System to ensure holes are clean. Alternatively, clean dust and debris from hole with stiff wire or nylon brush and blower in the following sequence: blow x 4, brush x 3, blow x 4, brush x 3, blow x Insert mixing nozzle to bottom of hole. Fill hole to 3/4 the hole depth slowly, ensuring no air pockets form. 4. Insert rebar to bottom of hole while turning. 5. Allow to cure as per setting times.
