- Chemlok® 218 adhesive is a one-coat adhesive used to bond castable and millable urethane elastomers to metals and other rigid substrates. It is composed of a mixture of polymers and resins dissolved in an organic solvent system.
- Shelf life is one year from date of shipment when stored at 21-27°C (70-80°F) in original, unopened container. Do not store or use near heat, sparks or open flame.

1. Features and Benefits
- Environmentally Resistant - provides excellent resistance to water, salt spray, a variety of solvents and other environmental conditions.
- Convenient - requires no primer, reducing labor and costs.
- Versatile - bonds a variety of castable and millable polyurethane elastomers.

2. Typical Properties

3. Application
- Surface Preparation – Thoroughly clean metal surfaces prior to adhesive application. Remove protective oils, Chemlok® 220 Adhesive cutting oils and greases by solvent degreasing or alkaline cleaning. Remove rust, scale or oxide coatings by suitable chemical or mechanical cleaning methods.
- Chemical Cleaning
 Chemical treatments are readily adapted to automated metal treatment and adhesive application lines. Chemical treatments are also used on metal parts that would be distorted by blast cleaning or
where tight tolerances must be maintained. Phosphatizing is a commonly used chemical treatment for steel, while conversion coatings are commonly used for aluminum.
- Mechanical Cleaning
 Grit blasting is the most widely used method of mechanical cleaning. However machining, grinding or wire brushing can be used. Use steel grit to blast clean steel, cast iron and other ferrous metals. Use aluminum oxide, sand or other nonferrous grit to blast clean stainless steel, aluminum, brass, zinc and other nonferrous metals.

4. Shelf Life/Storage
Shelf life is two years from date of shipment when stored at 21-27°C (70-80°F) in an original, unopened container. Do not store or use near heat, sparks or open fl ame.
