LORD® 304 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 provides excellent adhesion to prepared metals, fiberglass reinforced plastics (FRP), phenolic, wood, prepared rubber and other materials. LORD 304 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 to +250°F (-34 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.
Surface Preparation – Remove soil, grease, oil, fingerprints, dust, mold release agents, rust and other contaminants from the surfaces to be bonded by solvent degreasing or alkaline cleaning.
On metal surfaces which are free of oxidation, use an isopropyl alcohol wipe. If necessary, use an abrasive material to remove tarnish. Always follow abrasion by a second cleaning to ensure removal of loose particles.
When bonding cured rubber, allow LORD 7701 adhesion enhancer/surface modifier to flash off before applying LORD 304 adhesive. Prime glass and ceramic surfaces with LORD AP-134 adhesion enhancer/surface modifier to promote adhesion.
Handle prepared surfaces carefully to avoid contamination. Assemble as soon as possible.
