Creative Materials 127-03
- Chemical Family
- Epoxy & Epoxy Derivatives
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.

- 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.
- Safety and Handling
Use with adequate ventilation.; Keep away from sparks and open flames.; Avoid prolonged contact with skin and breathing of vapors.; Wash with soap and water to remove from skin.
- Application Methods
- Injection
- Screen Coating
- Handling
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.. Shelf Life
