BONDMASTER: Epoxy Adhesive
Bondmaster has introduced Bondmaster E04, an epoxy adhesive designed to protect wire from breakages and wear around the comutators in high impact, high temperature, high speed, and high vibration rotor applications. This two-part epoxy can be applied direct on-line prior to the preheat oven during the trickle-coat resin process. Full cure will occur in the preheat oven prior to the trickle coating process. This process will eliminate off-line, UV curable processes, banding, shrink-wrapping and other methods currently used to protect wires from wear and breakage. E04 is a 1:1 mix ratio epoxy with a work life of 45 minutes and an instant cure through the pre-heat oven in most trickle varnish systems. This material is suitable for Class H motors 180 degrees C (365 degrees F). A simple 1:1 extruder can be used to apply the material on-line. E04 is available in several sizes, including 50ml, 200ml, and 400ml cartridges, and 5 or 19 liter pails.
