Abstract
PURPOSE: To prepare a curing accelerator useful for a two-pack type unsaturated polyester resin composition having stable gel time even after long-term storage, by treating a mixture of a specific cobalt soap with a specific compound and dehydrating the mixture.
CONSTITUTION: (A) 100 parts by weight of a cobalt salt of octeic acid or napthenic acid is mixed with (B) 1W100 parts by weight of hexamethylenetetramine and (C) 0.1W20 parts by weight of lactic acid, cobalt salt of lactic acid or that of acetic acid. (D) A solvent having a boiling point of ≥100°C at atmospheric pressure (e.g. toluene, etc.), (50W2,000 parts by weight on the basis of 100 parts by weight (A)+(B)+(C)), and (E) a solvent having a boling point of 60W90°C at atomospheric pressure and forming an azeotrope with water (e.g. n-hexane, etc.), are added to the above mixture and the mixture is thermally dehydrated. The solvent (E) is distilled off to give the desired curing accelerator
