Creative Materials 127-03

127-03 is a screen-printable, B-Stageable, thermally conductive, one part epoxy adhesive, suitable for application by screen-printing and syringe dispensing. 127-03 is designed to exhibit minimal flow during bonding. This product has excellent adhesion to copper, aluminum and ceramic and a variety of other substrates. Additional applications include, but are not limited to, die attachment, printed circuit board fabrication, advanced material composites, LED attachment, and heat sink bonding. The chemistry in 127-03 features excellent thermal stability and flexibility in the B-Staged form and is optimal for absorbing stress when bonding mismatched CTE substrates. 127-03 is a thermally conductive, electrically insulating version of 125-22.

    Cure Method
    B-stage Procedure

    Apply adhesive to substrate or release liner. Next apply heat to advance the curing to the non-tacky stage when cooled to room temperature. A temperature of 100°C to 120°C for 5 to 15 minutes is required, B-Stage time is mass related. User is encouraged to experiment for optimum drying time at a given temperature.

    Bonding Procedure

    To use, apply b-staged adhesive to one part, carefully align parts to be bonded, apply uniform pressure to maintain location. Cure for 15 minutes at 200°C, or 30 minutes at 175°C, or 1 hour at 150°C. For better adhesion of the bstaged film to the first part, it is suggested to warm the part to 40°C. Cure times given are mass related, timing should start after adhesive and substrates reach curing temperature.

    Curing Guidelines

    These temperatures and times are presented as a guide only. The end-user is encouraged to experiment to determine optimum curing schedule.

    Temperature (°C) Time (min.)
    150 60
    175 30
    200 15
    Handling And Storage

    Material is ready to use as received. Store frozen to maintain consistent flow properties. Allow material to warm up to room temperature before opening container. It is important to resuspend any settled filler before using. Be careful not entrap air while mixing. 127-03 can be thinned with small amounts of CMI 113-12 (fast drying), or 102-03 (slow drying) thinners.
