ABSTRACT:
This invention relates to a method of sealing resin to an alloy casting using either an aromatic solvent or an aqueous-based solution. The method includes providing a resin and combining the aromatic solvent with the resin to form a sealing coating which has a predetermined concentration by volume of resin to sealing coating. The method continues by heating the alloy casting to a first predetermined temperature and then selectively applying the sealing coating to the heated alloy casting. Finally the heated alloy casting is baked at a second predetermined temperature for a predetermined time period. Variations of this process using an aqueous-based solution include providing an aqueous-emulsified resin, and then combining the aqueous-emulsified resin with at least one base solvent to form a final aqueous-based solution which has a predetermined concentration by volume of base solvent to final aqueous-based solution. The process allows for the selection of differing materials to be combined.
