Chemlok 320/310-B Black Epoxy Adhesive
High-Performance Epoxy Adhesive
Chemlok 320/310-B Black is a two-component epoxy adhesive designed for robust bonding of cured rubber (treated with Chemlok 7701), metals, and plastics (both thermosets and thermoplastics). Its fast cure time, high temperature resistance, and excellent chemical resistance make it suitable for demanding industrial applications. The adhesive is solvent-free, nonflammable, and virtually odorless, making it an environmentally friendly choice.

Features and Benefits
- Fast Cure - rapidly cures when heated at 93-162 C (200-325 F).
- Durable - provides good impact resistance down to -40 C (-40 F).
- Environmentally Recommended - contains no solvent, nonflammable and virtually odorless.
- Environmentally Resistant - resists humidity, salt spray and temperature extremes.
- High Temperature Resistant - resists postbakes up to 204 C (400 F).
- Chemically Resistant - solvent resistant when cured; anti-corrosion processes including phosphatizing and ELPO (e-coat) coatings do not affect the adhesive or its bond strength.
Typical Applications
- Bonding cured rubber to various substrates
- Metal-to-metal bonding
- Plastic-to-metal and plastic-to-plastic bonding
Shelf Life/Storage
