-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 75oF.

 == Safety and Handling ==
 PTM&W epoxy products are made from raw materials carefully chosen to minimize or even eliminate toxic chemicals, and there fore 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, all epoxy resins and hardeners can be irritating to the skin, and prolonged contact may result in sensitization; and 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, 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.

 ES-6228 is generally referred to as “Structural Adhesive” or “Structural.”  Gray in color, it has the viscosity of molasses.  Primarily used to join two or more preformed parts; i.e. bulkheads to fuselage, potting bushings, etc.<br><br>

 Original Velocity plans called for microglass or flox as a bonding agent for preformed parts.  Microglass and flox are acceptable alternatives wherever Structural Adhesive is called for.  Around 2000 Velocity began using ES-6228 to install channel ducts and bulkheads.  It quickly became a favorite and is now prescribed for almost all parts bonding.<br><br>
