LORD® 7542 adhesive is an equal-mix, two-component urethane adhesive system used to bond FRP, SMC and other plastics with little surface preparation. This adhesive will also bond primed metals. LORD 7542 adhesive system is available in a range of working times to accommodate a wide variety of process requirements.
Shelf life is six months from date of shipment when stored in a clean, dry environment at 65-85°F (18-30°C) in original, unopened container. Prolonged exposure to temperatures below 50°F (10°C) during shipping or storage may cause variations in cured properties and/or significant reduction in shelf life.
After opening, protect adhesive from excessive exposure to moisture by installing desiccant cartridges and/or using dry nitrogen as an inert cover.
