LORD 305-1/305-2 (3003559 or 3003558) Ratio 1:1 General Purpose Epoxy Adhesive Slow Set 60-120 min

Brief Description

LORD 305 adhesive is a general-purpose, medium viscosity, two-component epoxy adhesive system. It is engineered to create strong, durable, and highly resistant bonds against chemicals and environmental factors. This adhesive can be cured at room temperature or with heat for accelerated processing.

Popular Applications & Uses

- Bonding prepared metals, fiberglass reinforced plastics (FRP), phenolic, and wood.- Adhering prepared rubber, including bonding cured rubber to itself and rubber to metal.- Used in applications such as gaskets, bushings, shock-absorbing devices, and rubber rolls.- Serves as an alternative to traditional fastening methods like welding, brazing, riveting, and other mechanical fasteners.

Industries that Commonly Use It

- Aerospace/Defense- Automotive Service/Repair- Cabinet & Woodworking- Cladding (architectural cladding industry)- Construction/Building Services- Countertop Fabrication- General Manufacturing- Government & Military- LED/Electronics- Metal Fabrication- Plastic Fabrication- Transportation/Specialty Vehicle (e.g., heavy-duty trucks, buses, trailers)

Special and Unique Features

- **Durable:** Provides load-bearing properties equal to or greater than the materials being bonded.- **Environmentally Friendly:** Contains no solvent, is nonflammable, and virtually odorless.- **Environmentally Resistant:** Resists moisture, sunlight, and weathering.- **Temperature Resistant:** Performs effectively in temperatures ranging from -30°F to +250°F (-34°C to +121°C).- **Chemically Resistant:** Withstands dilute acids, alkalis, solvents, greases, and oils.- **Excellent Engineering Properties:** Offers low shrinkage, good creep properties, and low water absorption.- **Slow Set Time:** Provides a working time of 60-120 minutes, allowing for precise assembly and adjustments.
