INHIBITION:
Although TC-5045 A/Bhas proven to be less inhibited in curing against most substrates some materials may cause inhibition or neutralization of the curing agent. Inhibition may easily be determined by brushing a small quantity of TC-5045 A/B over a localized area of the surface to be reproduced. If the TC-5045 A/B is gummy or uncured after the curing time, then you know the mold surface is acting as an inhibitor. Molds made from wood, plaster, metal or plastic should not cause inhibition if they are clean. To insure against possible problems, it is advisable to spray a RF barrier film (BJB product RF-5215) over any questionable surfaces. This is the best way of treating clays and surfaces that cause inhibition.
