Description
LORD® 310 adhesive is a modified, thixotropic, two-component epoxy adhesive system used to bond many types of prepared metals, prepared rubber, urethane, wood, stone, concrete, and plastics. Originally formulated for primerless adhesion to SMC, LORD 310 adhesive is used to bond disk drives, down-hole oil field equipment, automotive body panels and spoilers, and vibration-damping mounts. LORD 310 adhesive can be either room-temperature cured or heat-cured for faster processing.
Features and Benefits
- Durable – provides load-bearing properties equal to or greater than the materials being bonded.
- Environmentally Recommended – contains no solvent, is nonflammable, and virtually odorless.
- Environmentally Resistant – resists moisture, sunlight, salt spray, and thermal cycling.
- Temperature Resistant – performs at temperatures from -40°F to +400°F (-40°C to +204°C); resists postbakes up to 400°F (204°C); resists outgassing up to 225°F (107°C).
- Chemically Resistant – resists dilute acids, alkalis, solvents, oils, and hydrocarbons; anti-corrosion processes including phosphatizing and ELPO (e-coat) coatings do not affect adhesive or its bond strength.
- Excellent Engineering Properties – provides low shrinkage, good creep properties, and low water absorption
