Description
LORD 306 (306-1 Resin and 306-2 Hardener) adhesive is a general purpose, high viscosity, two-component epoxy adhesive system used for applications that require gap filling or non-sag characteristics on a vertical surface. This adhesive system conforms to military specification MIL-A-24456 for bonding plastic vibration damping tiles to steel. LORD 306 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, nonflammable and virtually odorless
- Environmentally Resistant – resists moisture sunlight and weathering
- Temperature Resistant – performs at temperatures from -30°F to +250°F (-34°C to +121°C)
- Chemically Resistant – resists dilute acids, alkalis, solvents, greases and oils.
- Excellent Engineering Properties – provides low shrinkage, good creep properties and low water absorption.
- Non-Sag – remains in position when applied on vertical or overhead surfaces allowing for greater process flexibility.
