Creative Materials 125-35C

125-35C is a syringe dispensable, 100 % solids, thermally conductive, electrically insulating, precatalyzed, epoxy adhesive. This system features excellent thermal stability, outstanding chemical resistance and excellent high temperature properties. Unlike conventional thermally conductive epoxy adhesives, 125-35C is flexible and is able to absorb stress when bonding mismatched CTE substrates. Applications include die attachment, printed circuit board fabrication, advanced material composites, LED attachment and heat sink bonding. This is an electrically insulating, thermally conductive version of 124-08C.

    Suggested Handling & Curing

    Material is ready to use as received. Remove product from freezer and allow material to warm to room temperature before opening container. Best results are obtained when product is cured at one of the following schedules:

    90 mins 80°C
    15 mins 120°C
    5 mins 150°C
    45 sec 175°C
