ABSTRACT:
The invention discloses a method by which a fluid heat reactive resin system is formulated below the melting point of the resin. This permits the application of coatings and the formation of shapes and powders from the fluid heat reactive system. Liquefied gases are used to solvate resins so that curing agents, hardeners, pigments and flow control agents, and especially curing agents which are too reactive to be mixed with the resins above the melting point of the resins may be dispersed in the resins.After dispersion, the fluid heat reactive resin system remains in a deformable state under ambient conditions for a transient processing time. The transient processing time is established and maintained by the inclusion of plasticizers and high boiling solvents in the heat reactive resin system.
