ABSTRACT:
An improved alkyd resin manufacturing process in which the alkyd resin is prepared by esterifying a polybasic acid and a polyhydric alcohol under reaction temperature conditions and water from the esterification is removed from the process; in the event gelation of the alkyd resin occurs in the process, the improvement that is used is the addition of sufficient water or steam while the alkyd resin is maintained at about reaction temperature conditions to reverse the gelation of the alkyd resin to form a gel-free liquid composition of the alkyd resin. Also, water or steam can be used in an alkyd resin manufacturing process to prevent or retard gelation of the resin.
Alkyd resins are widely used in paints and varnishes which are used for finish for wood, metal, polymer reinforced fiberglass and the like.
