1. The product should avoid contact with any organic matter, ionic compound, ethylene compound and alkyne compound, such as N, P, S, Sn, Pb, Hg, Bi, As, PVC, etc. These chemicals can poison the platinum catalyst and break down vulcanization.
2. The mixture of AB components should be used up within 12 hours. Higher temperature will cause its effective operating time to decrease.
