Description
LORD® 7800 adhesive is an equal-mix, two-component urethane adhesive system used to bond composites,SMC and plastics with little surface preparation. This adhesive will also bond painted metals, such as powder-coated, primed and e-coated. LORD 7800 adhesive system offers a range of working times by shifting between LORD 7800 curatives, accommodating a wide variety of process requirements while retaining the same mechanical and adhesion properties.
Shelf Life
Shelf life of each component is six months when stored in a clean, dry environment at 65-85°F (18-30°C) in original, unopened container.
After opening, protect adhesive from excessive exposure to moisture by installing desiccant cartridges and/or using dry nitrogen as an inert cover.
Features and Benefits
Rapid Cure Strength – provides rapid, outstanding cure strength development, allowing for faster manufacturing and processing.
Consistent Cure Speeds – low exotherm cure (rate of cure less affected by bondline thickness).
Low Tooling Temperature – allows accelerated cure with low heat up to 220°F (104°C), eliminating quality issues from ‘cold spots’ seen with other adhesives.
Enhanced Regulatory Profile – free of heavy metals.
Environmentally Recommended – does not contain ozone depleting chemicals.
Environmentally Resistant – resists weathering, humidity and salt spray.
Non-Sag – remains in position when applied on vertical or overhead surfaces, allowing for greater process flexibility.
