Finely powdered coating compositions comprising (1) an unsaturated polyester resin made up of (a) a polyol component containing not less than 30 mole percent of a glycol having cycloalkylene or phenylene group and (b) an unsaturated polycarboxylic acid component containing tetrahydrophthalic acid and/or a drying oil fatty acid, (2) a solid vinyl or allyl compound and (3) a curing catalyst, give coating layers which are very hard, tough and resistant to solvents by powder coating methods.

Unsaturated polyester resin composition

An apparatus for continuously making a mixture of viscous material with solid material, which comprises a pair of spaced mixing rolls for dragging the viscous material and the solid material into a gap between the mixing rolls to permit the materials to be mixed together. A pair of removal rolls, each rotatable at a higher speed than any of the mixing rolls, are provided below the mixing rolls respectively spaced a predetermined distance from the associated mixing rolls for removing layers of the mixture sticking in part to one mixing roll and in part to the other mixing roll, off from the mixing rolls. The mixture removed from the mixing rolls by the removal rolls falls downwardly onto a packaging process wherein the mixture is packed between a pair of carrier sheets of synthetic resin material.
