Close to edge, stress free anchoring. Suitable for use with zinc plated, hot dipped galvanized or stainless steel Chemset Anchor Studs. Resistant to cyclic loading and vibration.

1 17.1 CHEMICAL INJECTION ANCHORING 17.1 GENERAL INFORMATION Product Epcon C6 is a versitile pure epoxy anchoring adhesive Benefits, Advantages and Features Features Superior strength in shallow embedment. Close to edge, stress free anchoring. Suitable for use with zinc plated, hot dipped galvanized or stainless steel Chemset Anchor Studs. Resistant to cyclic loading and vibration. Resistant to alkaline conditions. Suitable for use in core drilled holes. Superior strength with grade 5.8 steel Chemset Anchor Studs. Suitable for underwater installations. Installation PERFORMANCE RELATED (Australia refer to ChemSet Reo 502 ) INSTALLATION RELATED Principal Applications Structural beams and columns Batten fixing Installing, handrails, balustrades and gates Racking Safety barriers Stadium seating Machinery and heavy plant hold down Installation temperature limits: Substrate: 5 C to 40 C. Mortar: 15 C to 35 C. Load should not be applied to anchor until the chemical has sufficiently cured as specified 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 Ramset ChemSet Anchor Stud/rebar to bottom of hole while turning. 5. Allow to cure as per setting times. Approximate Setting Times Substrate Temperature 40 C 30 C 25 C 20 C 15 C 10 C 5 C 0 C Gel Time (mins) Epcon C6 Loading Time (hrs) Note: Cartridge temperature minimum 15 C. Note: Cure time extended in flooded conditions. Refer to technical data sheet RAMSET
