FLXEP860 Black 2-Part Rubber-Toughened Epoxy Adhesive 1:1 Ratio Kit

FLXEP860 Black 2-Part Rubber-Toughened Epoxy Adhesive 1:1 Ratio Kit

FLXEP860 Black 2-Part Epoxy Adhesive Kit is a rubber-toughened, structural-grade adhesive supplied in a two-bottle system (resin + hardener). It provides superior peel strength, impact resistance, and vibration durability, making it ideal for loudspeaker building, repair, and other demanding bonding applications.

This epoxy bonds strongly to plastics, metals, composites, ceramics, wood, cloth, and aluminum. It is widely used for joining, gluing, potting, panel bonding, and structural reinforcement, especially where flexibility and shock resistance are required.

FLXEP860 is also available in a cartridge format for use with a dispensing gun — perfect for faster, cleaner, and more controlled applications.

Key Features of the FLXEP860 2-Part Rubber-Toughened Epoxy Adhesive Kit

• Two-Bottle Kit – Resin and hardener packaged separately for manual mixing.

• Cartridge Kit Option – Duo-Pak format for use with a dispensing gun ((PXDG50.1112) and static mixing nozzles (PMA5.4-17).

• 1:1 Mix Ratio – Easy-to-measure equal parts for reliable results.

• Working Time: 18-20 minutes at 77°F.

• Cure Profile: Handling strength in ~1 hour; full cure chemical resistance in 7 days at room temperature. Heat cure accelerates bonding.

• Rubber-Toughened Performance: Flexible cured film resists cracking, provides excellent peel strength, and endures high vibration.

• Gap-Filling Viscosity: High-viscosity formulation holds position in vertical applications and fills uneven bond lines.

• Temperature Resistant: Maintains bond strength in service environments from -40°F to 250°F.

Which FLXEP860 Epoxy Kit Is Right for You?

Quick Summary:

• Two-Bottle Kit → Most economical, mix by hand, no special tools required.

• Cartridge Kit → Cleaner, faster, and more precise; ideal for pros and production.

Recommended Applications for FLXEP860 Epoxy Adhesive

• Loudspeaker repair and manufacturing: cone to coil, spider bonding, magnet structure assembly.

• Bonding plastics, aluminum, steel, composites, ceramics, cloth, and wood.

• Applications requiring flexibility and toughness under vibration, impact, and thermal cycling.

• Structural or industrial bonding where conventional CA or rubber adhesives are insufficient.

How to Use the FLXEP860 Black 2-Part Epoxy Adhesive Kit

1. Mix equal parts resin and hardener (1:1 by volume or weight).

2. Stir thoroughly until the blend is completely uniform.

3. Pot Life: 18–20 minutes (2 oz. mass @ 77°F).

4. Handling Strength: Achieved in ~1 hour.

5. Full Cure: 7 days at room temperature for maximum strength and chemical resistance.

6. Accelerated Cure: Heat cure @ 200°F — 10 min for magnet bonding, 3–5 min for cone-to-coil.

Storage and Shelf Life of FLXEP860 Epoxy Adhesive

• Shelf life: 6 months at 60–80°F in sealed containers.

• Lower temperatures may temporarily increase viscosity.

• Higher temperatures may cause permanent viscosity changes.
