Procedure

In forming the structure of this example, the vinyl ester resin (available from The Dow Chemical Company under the tradename Derakane 411-45), the anhydrous pinacol and the water were preheated to about 52° C. The anhydrous pinacol and benzoyl peroxide were then dissolved in the vinyl ester resin with vigorous agitation. The water was then rapidly added with vigorous agitation continuing for a period of about 20 minutes to form an emulsion of pinacol hexahydrate in the resin. Thereafter, the dimethyl toluidine was added while mixing to form the final composition which was then poured into a mold. The composition set up quickly in the mold to form a rigid structure with the pinacol hexahydrate dispersed therein.
