Chemlok 213 adhesive can also be used to bond a wide variety of both polyether and polyester castable urethanes to metal, as well as bond certain thermoplastic polyurethanes (TPU).
Shelf life is one year from date of shipment when stored by the recipient 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
- Versatile – bonds metal to a wide variety of polyether and polyester castable urethanes of varying hardness, based on both TDI and MDI.
- Economical – eliminates the need to inventory several adhesives due to the adhesive's versatility.
- Convenient – requires only a single coat for most applications, minimizing application costs; bonds RIM urethane elastomers directly to aluminum or steel without the need for primers or prebaking.
- Process Compatible – accommodates a wide range of processing conditions, including extended prebake.
- Environmentally Resistant – adds durability for harsh environment exposure, including salt spray and water and temperature exposures, when used with Chemlok 219 primer.
- Time Saving – requires no agitation in preparation for use or during application, saving application time and reducing the potential for application errors. Non-settling Chemlok 213 adhesive is ready to dip or brush when opened.
- Fast Drying – dries fast to allow rapid turnaround times, reducing the number of coated parts kept in inventory.
- Durable – provides bond strengths greater than the tear strength of the urethane substrate.

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.
