- 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 160°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.

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. 125-22 can be thinned with small amounts of CMI# 113-12 (fast drying), or #102-03 (slow drying) thinners.
