A hot market <\/strong><\/h3>\n

We live in a world where technology is advancing at a rapid pace. One area where this advancement is most apparent in everyday life is in cars. We\u2019ve gone from a world where petrol and diesel-powered cars were the norm, to over 20% of new UK car sales being either fully electric or hybrid on average, according to ZapMap<\/a>.<\/p>\n

Electric vehicles (EVs) make extensive use of electric motors, with a constant push from this market for smaller, more lightweight and efficient motors. Smaller, lighter motors tend to get a lot hotter than their larger counterparts, as they have far less ability to dissipate the very high heat produced by these vehicles. Motor manufacturers are therefore facing ever-increasing demand for higher and higher temperature resistance, and motors with Class H insulation<\/a> are in particular highly sought after by EV manufacturers – these can withstand temperatures up to 180\u00b0C and are ideally suited for use in these vehicles.<\/p>\n

 <\/p>\n

Our Solution \u2013 High Temperature Magnet Adhesive, Permabond ES5516<\/strong><\/h3>\n

 <\/p>\n

To meet this industry demand, Permabond has developed a new high temperature magnet adhesive – Permabond ES5516. This heat-curing single-part epoxy adhesive offers outstanding hot strength performance, maintaining high-strength structural bonds at 180\u00b0C. This makes it ideally suited to the bonding of class H electric motor magnets, including those in permanent magnet synchronous motors. Other uses include fixing any small close-fitting parts where there is no ability to mechanically clamp.<\/p>\n

 <\/p>\n

A highly unique feature of this adhesive is its dual activation. Once the adhesive has been applied, the bond can first be sealed or \u2018tacked\u2019 with UV light, before being subsequently heat cured. This \u2018tack strength\u2019 helps to prevent adhesive outflows from bonded joints before curing. It\u2019s also of great help in applications where accurate alignment of parts is required, as parts can be tacked in place before entering the heat-curing process.<\/p>\n
