Chemosil® X 3960-21 adhesive in combination with Chemosil H 2 hardener creates a one-coat adhesive system designed for use in aggressive downhole environments for bonding a variety of nitrile compounds. This technology has been commercialized in oil and
gas stator applications where it provides excellent, high temperature fluid resistance to polar and non-polar fluids.
Addition of Chemosil H 2 hardener is required to create the two-component adhesive system that bonds a variety of difficult-to-bond elastomers to metal and many polymeric substrates.

Features and Benefits:

• Versatile - bonds a wide variety of elastomers to metal, plastics and fabrics; suitable for existing production lines; tolerates a wide variety of stock formulations; forms a dry film suitable for manufacturing molded rubber/metal parts.

• Convenient - requires only a single-coat for most applications reducing labor, solvent usage, inventory and shipping costs.

• Durable - provides high strength systems; provides superior adhesion to plated metals.

• Process Enhancer - single application allows for multiple molding cycles.

• Environmentally Resistant - provides excellent resistance to solvents, water, oils and other aggressive media.

Elastomers:

• Nitrile (NBR)

• Polyacrylate (ACM)

• Epichlorohydrin (ECH)

Shelf life is one year from date of manufacture when stored by the recipient below 25°C (77°F) in original, unopened container.
