For jobs requiring rapid repair, Epibond 1559-1 A/B and C/D are an ideal choice for epoxy adhesives due to their quick set times, particularly at colder temperatures. These adhesives are both self-extinguishing pastes that are made up of two separate parts and are suitable for a multitude of bonding applications. Epibond 1559-1 A/B and C/D work best when bonding composite laminates, metals, most thermoplastics, and materials that are dissimilar from one another. These products are great choices when repairing or fabricating interior parts on aircraft, and also satisfy O.S.U. and FAR 25.853 requirements when they are used alongside low combustible composite components.
Epibond 1559 Systems call for a simple one to one mix ratio. Parts A and B are provided in contrasting colors in order to effortlessly indicate that the parts have been thoroughly mixed. When the paste turns to one even shade of gray, mixing is complete. Parts C and D are ideal for bonding applications on the interior of aircraft as both parts are an off-white color. The handling strength of these adhesives can be accomplished in as low as ten minutes, and in one hours’ time, high strength will be reached.
The density of Epibond 1559 part A, B, and A/B System is 1.20 g/cc. The viscosity of part A Resin is 90,000 cP at 77°F (25°C), part B Hardener and A/B System is 80,000 cP at 77°F (25°C). The gel time for Epibond A/B System is 6 minutes for 50 gms at 77°F (25°C), and the shelf life for Epibond 1559 parts A and B is 12 months when kept unopened and at a temperature of 77°F. If further technical data on Epibond 1559 A/B is required, please see the Epibond 1559 Technical Data Sheet.
Epibond 1559-1 A/B and C/D should be stored at or above 75°F (23°C). The containers holding these pastes should be placed in an oven at 120°F (49°C) for up to 15 minutes (no longer than 30 minutes) if the material has become crystalized. After the pastes have been removed from the oven and before mixing, ample time should be allowed for the materials to cool to room temperature. The suggested cure schedule for these materials is 24 hours at 77°F (25°C) or 30 minutes at 158°F (70°C). For added information regarding handling precautions and application methods for Epibond 1559-1 A/B and C/D, please contact a Krayden Technical Representative.
Epibond 1559 Systems are both two-part epoxy adhesives designed for applications in need of a rapid set time. These materials work best when applied to surfaces that are unlike one another. For use inside of aircraft, it is best to use Epibond 1559 C/D, as the color of the paste if off-white.
