The problem of the potential for creation of a reactive noncompressible crust in a fluid adhesive mixture comprising a deposit of an uncured curable fluid curable resin composition and a deposit of a fluid curing agent wherein the deposits are separated by a thin flexible barrier film formed from the interaction of the cured resin as reacted by the curing agent, is overcome by including with the fluid curing agent a thickener in an amount sufficient to render the fluid curing agent non-free-flowing at room temperature and preventing the formation of any substantial amount of noncompressible crust in the mixture.
