Description
LORD® 310 A/B is a thixotropic, two-part epoxy adhesive engineered for tough, long-lasting bonds on metals, plastics, rubber, urethane, wood, stone, and composites. It delivers exceptional structural performance and environmental durability for demanding industrial applications. Originally formulated for primerless adhesion to SMC, LORD 310 is ideal for automotive, electronics, oilfield, and general assembly uses where strength and resilience matter most.
Available in 50 mL and 210 mL dual cartridges for manual or pneumatic dispensing.
Key Features & Benefits
