Description
LORD 320/310-B Black is a two-component epoxy adhesive supplied in a 50 mL 1:1 cartridge for bonding cured rubber, metals, and plastics. It is a good fit when you need a paste adhesive that can be applied in a controlled bead, reaches full room-temperature cure in about 24 hours, and can be accelerated with heat for faster assembly cycles.
Key Features and Benefits
- 1:1 cartridge format meters the resin and hardener correctly for bench and field dispensing.
- Black paste consistency stays where it is placed and supports controlled bondline buildup.
- Working time of 0.5 to 1 hour gives enough open time for part alignment and assembly.
- Fast heat-assisted cure supports higher throughput when production can use an oven cycle.
- Cured adhesive resists humidity, salt spray, and temperature extremes in service.
- Good impact resistance down to -40°F supports demanding industrial environments.
Common Applications for LORD 320/310-B Black
- Bonding cured rubber treated with LORD 7701 adhesion enhancer
- Joining metals and plastics in industrial and transportation assemblies
- Repair work where a bead-applied structural epoxy is easier than mechanical fastening
- Shop production that needs handheld cartridge dispensing with optional heat cure
- Assemblies that will be filed, sanded, machined, or coated after cure
Compatible Materials
