Product Description
LORD® 305-1/305-2 Epoxy Adhesive is a general-purpose, medium-viscosity, two-component epoxy adhesive designed to produce strong, durable, chemically and environmentally resistant structural bonds. It provides excellent adhesion to prepared metals, fiberglass reinforced plastics (FRP), phenolics, wood, prepared rubber and other engineering materials. The adhesive is also suitable for bonding cured rubber to itself and rubber to metal, including gaskets, bushings, shock-absorbing devices and rubber rolls. LORD® 305 can be cured at room temperature or heat cured to accelerate production while delivering reliable performance across a service temperature range of -30°F to +250°F (-34°C to +121°C). :contentReference[oaicite:0]{index=0}
