\n Commutator Securing<\/span>\n with UV Adhesives<\/span>\n <\/h1>[\/vc_column][vc_column width=”1\/2″][vc_column_text css=””]Hoenle has developed special adhesives for securing wires to commutators that are extremely impact-resistant and cure quickly under UV light, making oven processes superfluous. These adhesives are highly viscous and stable, but at the same time flow into cavities thanks to optimized flow properties. The adhesive can be applied in a ring around the commutator in automated processes.[\/vc_column_text]\n

Adhesive properties include a wide range of elongation values, high Tg values for reduced movement and improved elasticity to meet the operational requirements of the stator, rotor and magnets under high temperatures, shock and vibration. The Hoenle adhesive portfolio is broad and includes 1- and 2-component epoxy resin adhesives as well as UV-, light- and dual-curing adhesives. They are particularly suitable for the various assembly and coating applications associated with the assembly of electric motors.[\/vc_column_text][\/vc_column][vc_column width=”1\/3″][vc_single_image image=”7913″ img_size=”full” css=””][vc_column_text css=””]Commutators can be bonded quickly and reliably\u00a0with UV adhesive[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column][vc_column_text css=””]Technical data sheets can be downloaded by clicking on the adhesive name.[\/vc_column_text]\n
