- B-stage Procedure
Apply adhesive to substrate. Next apply heat to advance the curing to the slightly tacky stage (when cooled to room temperature). A temperature of 65°C for 15 -30 minutes is required (B-Stage time is mass related). User is encouraged to experiment for optimum drying time at a given temperature. Store on release liner to prevent contamination.

- Curing Guidelines
128-38 is a one component system and is ready to use as received. Store frozen to maintain consistent flow properties. Allow material to warm up to room temperature before opening container. Prior to using mix container well. For hermetic lid attach applications, B-stage the material for 30 minutes at 65°C and bond the parts applying uniform pressure. Then cure for 90 minutes at 80°C. As a coating, cure for one (1) hour at 150°C, or 30 minutes at 175°C. 128-38 can be thinned with small amounts of CMI# 113-12 thinner if needed.
