304-1 / 304-2 | LORD Epoxy Adhesive
LORD® 304 adhesive is a general purpose, high viscosity, two-component epoxy adhesive system used for applications that require gap filling or non-sag characteristics on a vertical surface. This adhesive system provides excellent adhesion to prepared metals, fiberglass reinforced plastics (FRP), phenolic, wood, prepared rubber and other materials. LORD 304 adhesive can be either room temperature cured or heat cured for faster processing.
Shelf life is two years from date of manufacture when stored at 60-80°F (16-27°C) in original, unopened container.
LORD 304-1 resin will crystallize if exposed to temperatures below 60°F (16°C), resulting in a lumpy or grainy appearance. If resin exhibits any indication of crystallization,heat material to 80°F (27°C) for 6 hours, mixing occasionally by hand. Be sure to scrape down sides and bottom of container. Continue to heat and mix until material is smooth and homogenous. Allow material to reach room temperature before application.
