Aqueous solutions of inorganic nitrate salts are used to accelerate the
gelling of epoxy gelcoat resins without adversely affecting the glass
transition temperature of the finally cured gelcoat. The aqueous
accelerants may be used to accelerate gelling of gelcoats that are formed
during initial fabrication of composite parts. The aqueous acclerants are
also useful for shortening the gel time of gelcoats that are intended for
use in repairing damaged structures.
