Chemlok 6220 is a covercoat adhesive designed to bond a wide range of elastomers to metal substrates. It comprises a mixture of polymers, organic compounds, and mineral fillers dispersed in an organic solvent system. The adhesive provides reliable heat resistance, performing well at temperatures up to 149°C (300°F), and demonstrates superior resistance to salt spray and corrosive environments. Chemlok 6220 is intended for use in combination with Chemlok 205 primer to ensure effective bonding across multiple elastomer types, including natural rubber, nitrile, and polyacrylate. The adhesive cures during the rubber vulcanization process, forming a durable interface between elastomer and metal surfaces. Application methods include brushing, dipping, or spraying, with careful attention to maintaining proper dry film thickness. Users should follow recommended surface preparation procedures, including cleaning, degreasing, and rust removal, to achieve optimal adhesion.
