1 18.1 CHEMICAL INJECTION ANCHORING 18.1 GENERAL INFORMATION Product is a heavy duty Vinyl Ester anchoring adhesive. Benefits, Advantages and Features Suitable for structural applications: High bond strength Suitable for use in contact with drinking water: Meets AS/NZ Suitable for diamond cored holes: High bond strength Versatile Suitable for cold and temperate climates VOC Compliant High Productivity Fast Cure Easy cold weather dispensing Australian Made Installation PERFORMANCE RELATED Principal Applications Structural steel Starter bars Handrails Timber frames in domestic housing Installation temperature limits: Substrate: 0 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. INSTALLATION RELATED 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. ChemSet Injection to cure as per setting times. 6. Attach fixture. Setting Times Substrate Temperature 40 C 30 C 25 C 20 C 10 C 5 C Gel Time (mins) 801 Loading Time (mins) Note: Cartridge temperature minimum 5 C RAMSET
