BEP870 50ml Black Epoxy Adhesive Cartridge 1:1 Ratio

The BEP870 50ml Black Epoxy Adhesive Cartridge is a two-part, toughened structural adhesive engineered for high-strength, fatigue-resistant bonding applications. Packaged in a Duo-Pak cartridge, it provides clean dispensing, precise metering, and reliable mixing when used with the PXDG50.1112 dispensing gun and static mixing nozzles (PMA5.4-17S.

Formulated for high impact resistance and long-term durability, BEP870 bonds securely to metals, ceramics, wood, cloth, and composite materials. It is widely used in loudspeaker assembly and repair, panel bonding, potting, and general structural reinforcement where a strong, rigid bond is essential.

For added flexibility, BEP870 is also available in a two-part bottle kit (resin + hardener) for manual mixing — an economical option for small batch users, repairs, or situations where a dispensing gun is not available.
