ES6247 High Peel Strength Epoxy Adhesive
DESCRIPTION
ES6247 is a two component toughened epoxy adhesive with very good cured properties that provides excellent bonds to a variety of substrates. Its blend of high lap shear and T-Peel values allow superior performance in demanding bonding applications. ES6247 adheres very well to wood, metal, composites and some plastics. The bonded components exhibit tough and durable performance for long term stability in use.

DIRECTIONS FOR USE
Preparation: All surfaces to be bonded or patched must be free of dirt, oil and grease. 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 ES6247 A and B, 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 & Curing: Apply mixed material to roughened area of the parts to be bonded. Press
surfaces firmly together and let set for 16 hours or more at 75°F. If
necessary, place assembly in a jig or other device to prevent movement
during initial curing time. Curing time is 16 hours at 75°F, plus 3
hours at 180°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 & 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, 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 reactions, 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 are 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.
