Adhesive Performance on Elastomers

In this section, a guide is given to indicate the performance of several different adhesives for a selection of elastomers and thermoplastic elastomers. Most of the performance data was taken from The Loctite Design Guide for Bonding Rubber issued by Henkel Ltd [2] and for more detailed information the reader should refer to this guide. 

The nine different adhesives selected for these charts were as follows  

In addition, there are also many types of additives and fillers produced by many different companies and some will significantly influence the adhesion to the elastomer in question and so it is recommended that trials are conducted before selecting the most appropriate adhesive for the application. 

A brief description of each adhesive is given together with a few general comments on the overall performance of the adhesives. 

The alkoxy silicone often showed a strength of 0.4 N/mm for many of the elastomers tested but in this case the adhesive has failed cohesively. A silicone adhesive is often used where sealing might be the main priority of the adhesive rather than structural strength.
