Greater security: • Exceeds steel strength up to AISI 316 Stainless Steel at recommended embedments • High loads in shallow holes in thin slabs
Principal Applications • • • • •
Versatile pure epoxy: • • • • •
Anchors in dry, damp, wet and flooded Oversized holes into 2.25xdb Anchors in carbide drilled and diamond cored holes For tropical and temperate climates Easy flow version for easy cold dispensing (REO502™EF)
Reinforcing bars Deformed bars Starter bars Anchoring structural steel to concrete Anchoring stadium seating
Greater safety: • Low odour • Non-flammable for transport and storage • VOC Compliant
Installation temperature limits: REO502™ REO502™EF • Substrate: 5°C to 40°C. • Substrate: 5°C to 30°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.

1. 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 4. 3. 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 ChemSet™ Reo 502™ to cure as per setting times.

For conversion to Working Load Limit MULTIPLY ØNuc x 0.55 ***Note: Reduced characteristic ultimate steel tensile capacity = ØNus where Ø = 0.8 and Nus = Characteristic ultimate steel tensile capacity. For conversion to Working Load Limit MULTIPLY ØNus x 0.56 #Note: Design Tensile Capacity ØNur = minimum of ØNuc and ØNus WET HOLES: Multiply ØNuc x 0.7
