because the pdms with benzonyl peroxide, as the article says, does not crosslink the polymer pdms without any dopant at 150 degrees 160, 170 and 180 degrees, there is some other crosslinking agent or curing agent for dimethicone (pdms) other than sylgard that is very expensive?,I study physics but I thought it was going to be cured with radical peroxide but it did not polymerize, I have even tried it for 1.5 hours with relation 10:1 ,thanks.
