PREPARATION: When using epoxy adhesives, all surfaces to be bonded or patched must be free of dirt, oil and grease. Sanding or roughening the area to be bonded increases the surface area and enhances the bond. Surface treatments and preparation procedures are available that improve the adhesion to specific surfaces. Check with our Technical Services Department for information regarding your particular application.
MIXING: Measure out the correct amount of resin and hardener, combine, and mix thoroughly until a uniform 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 the properly prepared surfaces of the parts to be bonded. If necessary, place assembly in a jig or other device to prevent movement during initial curing time. ES6296 will cure at room temperature, but, a heat cure is required to achieve the full heat resistance and stability the material is capable of. Therefore, ES6296 should be heat cured to achieve full cure and maximum properties. The data listed in this bulletin were obtained with one of the following cure cycles: 1. Overnight at Room Temperature (77OF minimum), plus 6 hours at 210OF, or 2. Overnight at Room Temperature (77OF minimum), plus 6 hours at 230OF. Testing is continuing to establish optimum cure times at various temperatures for maximum properties.

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.
