Lord Adhesives 305 Epoxy Adhesive System
Categories: Polymer; Thermoset; Epoxy; Epoxy Adhesive

Material Notes: LORD® 305 adhesive is a general purpose, medium viscosity, two-component epoxy adhesive system used for applications that require strong, durable, chemically and environmentally resistant bonds. This adhesive system provides excellent adhesion to prepared metals, fiberglass reinforced plastics (FRP), phenolic, wood, prepared rubber and other materials. It is also used to bond cured rubber to itself and rubber to metal, including gaskets, bushings, shock-absorbing devices and rubber rolls. LORD 305 adhesive can be either room temperature cured or heat cured for faster processing.

Features: provides load bearing properties equal to or greater than the materials being bonded. contains no solvent, nonflammable and virtually odorless. resists moisture, sunlight and weathering. performs at temperatures from -30°F to +250°F (-34°C to +121°C). resists dilute acids, alkalis, solvents, greases and oils. provides low shrinkage, good creep properties and low water absorption.
