摘要:
A shellac coating composition for producing a shellac coating on a substrate comprises a fatty acid component, shellac and little or no volatile carrier liquid. Because the fatty acid inhibits the polymerization of the shellac when molten, the composition can be converted into a liquid state for coating purposes by simple heating, thereby eliminating the need for the volatile carrier liquid.
摘要:
A powder coating characterized in that pigment particles are bonded to a base coating powder through shellac. The powder coating exhibits the strong and uniform bonding of pigment particles to the base coating powder thereof and also can provides a coating film exhibiting excellent designability, due to the action and effect of shellac. The powder coating is free from the separation between pigment particles and a base coating power, which are components thereof, exhibits good application workability, and can provide a coating film which has a smooth surface, is excellent in designability and exhibits high resistance to water, and further, is excellent in productivity and economy, since the powder coating having not been adhered to an article to be coated can be recycled and reused.

Preparation of lacquer comprising resin and/or a dispersion, and optionally wetting agents, defoamers, waxes, solvents and leveling agent, comprises adding resin or solution of resin and optionally dispersion, wetting agents, wax, solvents, leveling agents and further matting agent under stirring for 1-6 hours, and further stirring with the addition of water in order to adjust the desired viscosity of the lacquer. An independent claim is included for the lacquer comprising resin and/or a dispersion, and optionally wetting agents, defoamers, wax, solvents and leveling agent, where: the resin is a modified natural resin and the dispersion is an aqueous dispersion of copolymers of shellac, aqueous dispersion based on polylactic acid, and/or aqueous dispersion based on cellulose; and the lacquer contains greater than 25 wt.% of resin and dispersion and remaining quantity of water.
摘要:
Ein Herstellungsverfahren für einen Lack, aufweisend Harz und/oder eine Dispersion sowie ggf. Netzmittel, Entschäumer, Wachs, Lösemittel und Verlaufsmittel wobei einem Harz oder einer Lösung von Harz ggf. die Dispersion, Netzmittel, Wachs, Lösemittel, Verlaufsmittel sowie ggf. bei Mattlacken zusätzlich Mattierungsmittel unter Rühren hinzugegeben und für etwa 1 bis 6 h, ggf. unter weiterer Zugabe von Wasser zwecks Einstellung der gewünschten Viskosität des Lackes weiter gerührt werden, dadurch gekennzeichnet, dass zur Herstellung der Lösung des Harzes Wasser, Festharz, Entschäumer und Neutralisationsmittel, z. B. Ammoniak zu einer wässrigen Harzlösung während eines exothermen Lösungsprozesses zugegeben werden, dass der pH-Wert dabei zu Anfang nicht unter pH 9 liegt und dass der pH-Wert während des Rührens durch entsprechende Nachdosierung des Neutralisations- mittels zwischen pH 8 und 10 gehalten wird.
摘要:
The present invention provides a powder paint excellent in productivity and cost, because the powder paints that are not adhered to the substrate can recovered and reused. And in case of using the powder paint of the present invention, coating efficiency is high and fine textured coated films excellent in attractiveness of appearance and water resistance can be obtained, because the base paint powder and the pigment particle thereof hardly separate. The powder paints of the present invention are characterized in that the pigment particles are bound to the base paint powders via shellac. The powder paints of the present invention not only allow uniform and firm binding of pigment particles to base paint powders by the action of shellac, but also provide the resulting coated films with excellent attractiveness of appearance.
