The samples are cured for 10 min. at 103'C., primarily to flatten-out the PVC sheeting. Although No.2 requires heat for a good cure, No. 1 will cure at room temperature. The curing time and the pot life will depend upon the temperature used. In the event that a lengthy processing time is required, a two-part mix can be used. A DMP-30 and Hycar MTBN mixture can be one part and Epon 828 the other.
