What is an Epoxy Adhesive?

Epoxy adhesives are two-component systems consisting of a resin and a hardener. When mixed, they undergo a chemical reaction to form a strong, durable bond. Epoxies are renowned for their high strength, chemical resistance, and ability to bond a variety of substrates.

Key Features

• Extended 90-minute work life for precise application
• High shear and peel strength for durable bonds
• Flexible formulation accommodates movement and vibration
• Bonds to metals, ceramics, wood, glass, rubber, and many plastics
• Room temperature curing with optional heat acceleration
• Available in gray and translucent formulations

3M™ Scotch-Weld™ Epoxy Adhesive DP190 offers a combination of strength and flexibility, making it ideal for applications requiring durable bonds that can withstand environmental stresses. Its extended work life allows for meticulous assembly, reducing errors and rework. The adhesive’s compatibility with various substrates simplifies inventory and application processes.

Key Benefits:

• Long working time facilitates complex assemblies
• Strong adhesion to diverse materials reduces the need for multiple adhesives
• Flexible bond resists impact, vibration, and thermal cycling
• Room temperature cure enhances production efficiency
• UL 94 HB flammability rating ensures compliance with safety standards

Applications

• Bonding metals to plastics in electronic assemblies
• Wood to metal bonding in furniture manufacturing
• Plastic to plastic bonding in automotive components
• Semi-flexible potting compound for electrical components
• General industrial bonding where flexibility and strength are required

How to Use

Insert the Duo-Pak cartridge into a 3M™ EPX™ Applicator and attach the appropriate mixing nozzle. Dispense the adhesive onto clean, dry surfaces, ensuring even coverage. Assemble the parts within the 90-minute work life, applying uniform pressure to ensure proper contact. Allow the assembly to cure at room temperature; full strength is typically achieved in 7 days. For faster curing, moderate heat can be applied.

Cautions

• Ensure surfaces are clean and free from contaminants before application
• Avoid skin and eye contact; wear appropriate personal protective equipment
• Use in a well-ventilated area
• Store cartridges at recommended temperatures to maintain shelf life
• Refer to the Safety Data Sheet (SDS) for detailed handling and safety information
