Chemlok 487 A/B Adhesive
Two-component adhesive for bonding thermoplastic elastomers
Chemlok 487 A/B is a two-component adhesive designed for bonding thermoplastic elastomers (TPEs) to a wide range of substrates, including metals, glass, plastics (both thermoplastic and thermoset), and other elastomers. It's particularly effective for bonding Santoprene, Kraton, and Sarlink thermoplastic elastomers and is often used in injection molding processes. When bonding TPEs to glass, applying Chemlok 144 primer before the adhesive is recommended.

Features and Benefits
- Durable - provides a strong, durable bond that, in many instances, has strength equal to or greater than the elastomer being molded.
- Fast Drying - allows for spray application; provides a uniform coating over a large surface area, accelerated solvent evaporation and a shortened drying time.
- Versatile - bonds a variety of TPEs to a variety of substrates.
Typical Applications
- Injection molding
- Insert molding
- General bonding of TPEs to various substrates
Shelf Life/Storage
Shelf life of each component is one year from date of manufacture when stored by the recipient at 21-27 C (70-80 F) in original, unopened container.Chemlok 487 components are moisture sensitive. Minimize exposure to moisture during application and storage.To help prevent the formation of a gel-like consistency, store Chemlok 487A component above 21 C (70 F). If, however, a gel-like consistency does develop, heat Chemlok 487A component to temperature above 49 C (120 F) and shake material until it returns to a homogeneous liquid.
