Bonding

Polyurethane- or cyanoacrylate- based systems for bonding Desmopan® and Texin™ are supplied by the adhesives industry under a variety of trade names. Cyano-acrylate adhesives cure extremely quickly, but are brittle. The bonded joint breaks under pressure, so they are only suitable to a limited extent for elastic, flexible materials such as TPU. They should only be used for temporary bonds or bonds that are
not subject to bending.

Polyurethane adhesives take longer to cure but, like Desmopan® and Texin™, are flexible and elastic. They are therefore ideal for long-lasting bonded joints.

Only a few solvents (including NMP, DMF, MEK) dissolve Desmopan® and Texin™ to such an extent
that it is possible to produce a bonded joint. These solvents are harmful to health, and it is essential that the information given in the safety data sheets be observed.
