A decking coating composition applicator including a receptacle for holding a coating composition, and an applicator surface fluidly connected to the receptacle such that the coating composition can be supplied to the applicator surface, the applicator surface comprising a pad portion, and a bristles portion, in which the bristles portion is positioned outside of an area defined by the pad portion.
摘要:
A retransfer intermediate sheet for receiving an image to be printed onto an article by thermal retransfer comprises a substrate; and an image-receiving coating on one side of the substrate for receiving an image by printing of dye-containing ink, the coating comprising a fluid-absorbing layer and a superposed dye management layer comprising functionalised polyvinyl alcohol and/or an ionic polymer. The dye management layer functions to reduce back diffusion and to increase dye transfer efficiency, resulting in production of printed images of improved optical density. The sheet can be heat-deformable, and finds particular use in printing on 3D articles, e.g. being heated and vacuum formed to conform to an article. The invention also covers a method of printing and an article bearing a printed image.

摘要:
Coating composition comprising an oxidatively drying coating binder and a chelate comprising at least one group according to the following formula (I): forming a complex with a metal ion, A1 and A2 both being an aromatic residue, R1 and R3 being covalently bonded groups, and R2 being a divalent organic radical, wherein at least one solubilizing group is covalently bonded to the chelating compound. The solubilizing group is a non-polar group, preferably an aliphatic group having at least four carbon atoms, covalently bonded to A1 and/or A2. The metal ion is a divalent ion of a metal selected from the group of manganese, cobalt, copper, lead, zirconium, iron, lanthanium, cerium, vanadium, and calcium or a trivalent ion of a metal selected from the group of manganese, cobalt, lead, zirconium, iron, lanthanium, cerium, and vanadium, combined with a monovalent counterion.
摘要:
Coating compositions are disclosed having a non-bisphenol A based film forming resin and an adhesion promoter resin. The coating compositions provide an alternate to epoxy resins that still allow melamine formaldehyde free cure, blush resistance, capability to retort and can withstand hard-to-hold beverages. In some embodiments, the coating compositions are used to coat substrates such as cans and packaging materials for the storage of food and beverages. Substrates can be coated by preparing an adhesion promoter composition by a method including mixing an epoxidized resin and a solvent to form a mixture, adding a phosphoric acid compound to the resulting mixture to form a phosphate ester, adding water to partially hydrolyze the phosphate ester, and adding a neutralizer to form the adhesion promoter resin, followed by blending the adhesion promoter resin with a non-bisphenol A based film forming resin to form a coating composition, and applying the coating composition to the substrate.
