Pro-Poxy™ 204 is a 100% solids, fast setting, two component, high modulus, medium viscosity, moisture tolerant structural epoxy adhesive that meets the requirements of ASTM C-881 and AASHTO M-235. The Pro-Poxy™ 204 is slightly thinner than the Pro-Poxy™ 200.
Surface to be bonded must be clean and sound. Remove oil, dirt, grease, laitance, curing compounds and other foreign matter that may cause a problem with bond. Abrasive blast cleaning and mechanical removal methods are recommended. All drilled holes must be cleaned with a cylindrical bristle brush to remove all loose material. Use clean, oil free, compressed air to blow out any remaining dust or debris prior to installation.
Condition material to 65°-85°F (18°-29°C) before using. Premix each component then place 1 part by volume of Component A and 1 part by volume of component B into a clean pail and mix for three minutes with a low speed drill using a Jiffy mixer or paddle until uniformly blended. Mix only what can be used within the pot life. Air, material, and surface temperatures must be 40°F (5°C) prior to mixing or installation.
As a structural adhesive and for bonding fresh concrete to hardened concrete, apply the Pro-Poxy™ 204 material neat by brush, roller or spray and work into substrate. While Pro-Poxy™ 204 is still tacky, place the fresh concrete.
For anchoring dowels, bolts, reinforcing steel, etc., the depth of the hole should be approximately 9 to15 times the bolt diameter. The space (annulus) around the bolt in the hole should not exceed 1/8 in. (0.3 cm). Always dispense the Pro-Poxy™ 204 into the anchoring hole filling from the bottom up. Insert the bolt, dowel or anchor turning slowly during insertion. After insertion, the hole should be completely full of epoxy.
