Pre-treatment of Substrate: Product Packaging Concrete Surfaces: Chem- Dowel 2 2 and 10 gal/pack The surface or holes must be clean, dry, free from grease or ( and kg/pack) oil, etc. Laitance and loose particles must be removed by either sandblasting or mechanical grinding. Holes must be cleaned using dry and oil free compressed air.

6 Steel Surfaces: in thin layer Chem- Dowel 2 on both surfaces. Pull them All steel surfaces to be bonded with Chem- Dowel 2 must be together and hold into position undisturbed for 6 8 hrs. clean, dry, free from rust, oil, grease, etc. Shot blasting to Curing: Swedish Standard SA 2 is preferable to achieve a white Initial Setting is minimum 8 hours. Full cure in 3 days. metal finish prior to application. Holes For Setting Dowels: CLEANING. Holes Dimensions: The annular space between anchor rod, Remove uncured Chem- Dowel 2 from tools and equipment Dowel , rebar, etc.

Cured material may only be removed mechanically. Depth of Embedment Guidelines: * When substrate has compressive strength of 3000 psi (21 STORAGE. N/mm ) and greater or the anchor bolts are threaded, the Store in a dry area between 50 F and 77 F (10 C and 25 C). minimum depth is 10 times the bolt diameter. Protect from direct sunlight. * For grouting smooth bolts or into substrates with less than SAFETY PRECAUTIONS.

8 3000 psi (21 N/mm ), the minimum depth of embedment After full curing the product is physiologically harmless. Keep is at least 15 times the bolt diameter the resin and hardener away from the eyes, mouth and skin. Drilling: Do not inhale vapors. Uncured mixture can cause irritation of * Dry Drilling: Vacuum or blow out the dust from hole the skin. The best precaution is to wear safety protective using oil free compressed air or blow pump gloves, overall, mask and goggles while working. Skin * Wet Drilling: Wash out hole with clean water to remove contamination should be immediately cleaned with soap and residue of drilling slurry.
