Non-mechanical joining for hybrid construction
Keywords Sika, Bonding, Joining, Corrosion prevention
Sika Ltd launched its new technical manual on elastic bonding at the recent Weldex exhibition. The manual highlights what Sika believes to be a highly cost-effective method of non-mechanical joining. According to the company, its bonding systems are use-proven in the commercial, automotive manufacturing, shipbuilding and brown and white goods industries (Plate 1).

The company considers that its bonding systems enable hybrid construction, plus the use of a wide range of dissimilar materials. Elimination of galvanic corrosion when bonding metal to metals is another advantage claimed for the product. Sika's bonding systems are also said to allow use of thinner materials, resulting in cost and weight savings.
The bonding systems are said to provide a surface that will accept paint finishes. It also claimed that the polyurethane based adhesive system eliminates operations such as grinding, and the need for smoke extraction systems, while forming an aesthetic, watertight and rust free joint.
