Accelerated curing of epoxy gelcoats

   
   

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.
