PREPARATION: All surfaces to be bonded or patched must be free of dirt, oil and grease. The ability of ES6228 to bond to slightly oily surfaces should be considered as “insurance” for a good bond, rather than justification to avoid adequate surface preparation. The better the surface prep, the better the results! Sanding or roughening the area to be bonded increases the surface area and enhances the bond. See PTM&W Bulletin “Guidelines for Metal Surface Preparation” for more information. MIXING: Measure out equal parts of ES6228 A and B or B1, combine, and mix thoroughly until a uniform gray color and consistency is reached. Mix for at least 1 to 2 minutes, scraping the sides and bottom of the container to avoid leaving unmixed material that will cause soft spots in the cured material.
APPLICATION and CURING: Apply mixed material to roughened area of the parts to be bonded. Press surfaces firmly together and let set for 24 hours or more at 75o F. If necessary, place assembly in a jig or other device to prevent movement during initial curing time. Curing time is 24 to 36 hours at 75o F, or 2 hours at 140o F. The material to be bonded may be preheated to accelerate curing time, or very light heat can be applied after the parts have been bonded.

Safety & Health
- Safety And Handling
PTM&W epoxy products are made from raw materials carefully chosen to minimize or even eliminate toxic chemicals, and therefore offer the user high performance products with minimum hazard potential when properly used. Generally, the PTM&W epoxy resins and hardeners will present no handling problems if users exercise care to protect the skin and eyes, and if good ventilation is provided in the work areas. However, breathing of mist or vapors may cause allergenic respiratory reaction, especially in highly sensitive individuals. As such, avoid contact with eyes and skin, and avoid breathing vapors. Wear protective rubber apron, clothing, nitrile rubber gloves, face shield or other items as required to prevent contact with the skin. In case of skin contact, immediately wash with soap and water, followed by a rinse of the area with vinegar, and then a further wash with soap and water. The vinegar will neutralize the hardener and lessen the chances of long term effects. Use goggles, a face shield, safety glasses or other items as required to prevent contact with the eyes. If material gets into the eyes, immediately flush with water for at least 15 minutes and call a physician. Generally, keep the work area as uncluttered and clean as possible, and clean up any minor spills immediately to prevent accidental skin contact at a later time. Keep tools clean and properly stored. Dispose of trash and empty containers properly. Do not use any of these types of products until Material Safety Data Sheets have been read and understood.
