    Abstract: Disclosed is a novel method for determining the degree of cure of polyester and epoxy resins which includes the steps of adding a catalyst, containing a pigment, to the resin; mixing the two components to provide a visually uniform distribution of the catalyst and pigment throughout the resin; and, depositing the mixture in a desired position for curing. The pigment can also be added directly to the resin rather than the catalyst. Additionally, in either alternative, at the completion of the curing the color imparted by the pigment has substantially disappeared from the cured product as though no pigment had been employed. Also disclosed is a novel benzoyl peroxide paste composition, for curing polyester resins, having a pigment the color of which substantially disappears from the cured product.

    Abstract: Described herein is an epoxy composition comprising: a first component comprising an amine-based curing agent and a first dye, having a first color; and a second component comprising a curable epoxy resin and a second dye, having a second color. Also described herein is a shelf-life-indicating composition comprising: an amine-based curing agent; and a dye selected from (i) a cationic triarylmethane dye, wherein the cationic triarylmethane dye reversibly reacts with a primary amine; (ii) a halochromic dye having a color transition range between 7-12 when measured in an aqueous solution; or (iii) combinations thereof.
