High gloss coating hardened during contact with smooth film - for continuous, rapid generation of high gloss coatings

Glossy coatings are continuously generated on the surface of sheet or film supports by applying a hardenable polymeric coating composition directly to the support or to a gloss flexible film and maintaining the coated face in contact with the glossy flexible film while the coating is laminated to the support layer and hardened by suitable irradiation. The glossy film is separated from the hard coated surface for re-use. Suitable for applying a glossy varnish to supports of paper, film, metallic sheet of foil etc. The contacting film generates a higher gloss than is usually obtained from coatings cast or spread with a free exposed surface. Provides a continuous short cycle polishing technique and high throughput rates (no data). The glossy film is of polyamide or polyolefin film travelling between storage and take-up reels or in a continuous loop. The covered coating is cured by electron bombardment or by UV, radiofrequency or microwave irradiation.

A transport device is provided to move the container through the magnetic field such that the longitudinal axis of the container is generally perpendicular to the longitudinal axis of the coil. This allows for heating the container at the twelve and six o'clock positions. The transport device functions to roll the container along the heating path. In a preferred embodiment, the coil is wrapped about a core with a generally rectangular shape. Ferromagnetic members may optionally be used to further shape the magnetic field. The methods and apparatus may be used for regular or irregularly shaped containers.

Method of forming a coating on a surface of a substrate

A reinforcing underlayment including dry uniform particles evenly applied to a wet bonding material layer on a surface of a substrate. The substrate, including the layers, is then cured to harden the one or more of the layers. A final coating or topcoat is applied to the cured surface of the substrate. The dry particles are evenly distributed onto the bonding material layer creating a uniform surface for subsequent coatings. The dry particles increase the strength of the liquid coatings increasing solid particle density within the coating system and thereby imparting properties not available for the liquid coatings. The present invention enables a user to easily introduce very heavy, dense, strong particles into a liquid coating and allows the user to apply very dense, heavy particles into and onto a wet bonding material layer followed by a subsequent wet topcoat layer which is cured as one contiguous material with reinforcement and underlayment strengthening coming from the added, dry particles.
