Abstract:
The present invention provides a method of making a coated golf ball having good adhesion of a paint, good uniformity of a thickness of paint layer, excellent safety and excellent productivity. The present invention relates to a method of making a coated golf ball comprising a golf ball body, of which the surface portion is formed from resin composition or rubber composition, and a paint layer formed on the golf ball body, wherein the paint is coated within 72 hours after molding the golf ball body in a mold.
Abstract:
A process for modifying the surface of a substrate containing a polymeric material by contacting the surface with the modifying agent to bond the modifying agent to the surface the process comprising providing a solution of the modifying agent in a solvent and subjecting the solution of the modifying agent to a zone of elevated temperature to vaporize the solvent and provide diffuse contact between the modifying agent and the surface of the substrate.
Abstract:
A process of producing a high gloss oxidizable extrusion coated polyethylene is provided. This process entails extrusion coating a low density polyethylene of narrow molecular weight distribution having a low melt index, a low swell ratio, and a polydispersity index below 9.

Physical method for the treatment of the surfaces of polyolefinic plastic laminates, polytetrafluoroethylene (PTFE), cardboards and metal sheets such as, particularly, aluminium and tinplate, of any thicknesses and widths, by means of a flame produced by the combustion of a mixture of air-hydrocarbon gas, characterized in that such a mixture is enriched with pure oxygen gas.
Abstract:
Method of drying on a web face an applied coating containing volatile products, involving feeding the web at a rate of at least 50 feet per minute past a station at which a flame sheet from a high-capacity burner is with its tip in contact with the coated face of the fed web transversely thereof for evaporating and igniting the volatile products in the passing coating, and featuring directing into contact with the coated face of the fed web on opposite sides of and adjacent to the contacting flame sheet stable air sheets of a velocity of at least 400 feet per minute.
Abstract:
A novel process for applying cured thermoset resinous coatings to various kinds of substrates and in particular, to thin metal substrates, is disclosed. Finely divided thermosettable resinous particles containing a solid catalyst are introduced into a region of a plasma arc generated flame having a temperature greater than the melting point of said resin. The residence time of said resinous particles in the vicinity of said flame is maintained for a period sufficient to liquify substantially said particles and to initiate polymerization of the thermosettable resin particles. The liquified resin particles are propelled towards a substrate with sufficient velocity to cause said liquified resinous particles to impact with sufficient force to cause said particles to flow upon said substrate to coat same with a continuous, thin coating. The coated substrate is then cooled at a rate sufficiently slow to permit said coating to cure. The plasma flame must be located sufficiently near the substrate so that the resinous particles possess sufficient thermal and kinetic energy to flow into a thin coating retaining sufficient energy therein to continue curing to a thermoset state without addition of energy. The kinetic energy of the particle facilitates formation of a thin, uniform coating and creates additional thermal energy upon impact with said substrate.
