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. ES6292 will cure at room temperature, but the cure time is usually too long for an acceptable production rate. As such, ES6292 is normally heat cured to achieve a good balance between full cure and reasonable production time. The material to be adhered may be preheated to accelerate curing time, or very light heat can be applied after the parts have been bonded. If no heat is applied, the bonded components will develop sufficient strength for removing from the fixture in 6 to 10 hours, depending upon ambient temperatureAt this point, the assembly can be heat cured to develop full properties. If faster curing by the application of heat is desired, the ES6292 should be allowed to gel at room temperature for 2 hours before heat is applied, to avoid expansion of the adhesive, or stress development in the joints. After this room temperature gel, the material can be oven cured. A typical oven cure would be 4 to 6 hours at 150o F to 160o F. Higher temperatures would cure the material in shorter time, and lower temps would be proportionally longer. Tests should be run to determine the optimum cure time for your components and setup.

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.
