I tried to dredge another number out of the old memory cells, but I keep comming back to PPG 5252. Dead cells? Two numbers associated with this task had a nice rhythm, like 5252 and 1418 for the UL crt implosion test document. Wonder if the 5252 number got recycled to another product after the process was retired.
The resin that was used was heated (85 C ?) in small batches and the mek-p catalyst was added and mixed in just before the pour was made. When cured, the resin had a rubbery consistency.
Good luck with your experiments,
