Mixing Instructions:
The base and curing agent are mixed just before using. Mix 1 part base to 1 part curing agent by weight. Automatic mixing equipment or manual mixing may be used to combine base and curing agent. Immediately after mixing, place the material in a vacuum chamber.
Inhibition:
Certain materials will cause inhibition or neutralization of the curing agent. These materials are sulfur containing organometallic salts containing compounds such as organic rubbers and many condensation cure RTV chloride solvents - amines. Inhibition may easily be determined by brushing a small quantity of R-2262 FR A/B over a localized area of the surface to be reproduced. If the R-2262 FR A/B is gummy or uncured after the curing time, then mold surface is acting as an inhibitor.
