(3) For sealant application life, tack- free curing
time, and curing rates (see following Cure Rate table).
B. Sealant Mixing
(1) For best results, use kits with proper propor-
tions of base compound and accelerator.
(2) To avoid excessive air entrapment, slowly
stir accelerator into base compound. Continue mixing
for seven to ten minutes. Scrape sides and bottom of
container to include all compounds in mixture and to in-
sure uniform blending. Scrape mixing paddle on edge
of container to remove unmixed compound. Be sure to
use all of the accelerator.
(3) Place small amount of mixture on a clean
strip of aluminum and spread sealant. Visually examine
sealant film to determine whether accelerator is visible
in particle form. If particles of accelerator are visible,
continue mixing operation. If course particles of accel-
erator persist after mixing thoroughly, reject entire
mixed batch.
