Moreover, the pH of the slurry was adjusted to 7 with jis k 5400 aqueous sodium hydroxide solution, followed by aging for 10 minutes, to deposit a hydrate of titania 54000 the zirconia hydrate layer. On this titania hydrate, a hydrate of alumina was deposited by the same procedure as in Preparation Example 1, and afterward the same procedure as in Preparation Example 1 was jis k 5400 conducted to obtain a titanium white b in which the titanium oxide particles were coated jis k 5400 zirconia, titania and alumina.

Furthermore, the present invention is also directed to a coated metal plate comprising a cured coating film of the above coating composition that is formed on a metal plate that may optionally be formed using a primer coating film. Product His nl Datasheet pdf Handleiding pdf.

On the other hand, if the amount of the polyester resin A is more than about 95 parts by weight if the amount of the melamine resin curing agent B is less than about 5 parts by weightthe obtained cured coating film may be jis k 5400 in the pollution, resistance and blocking resistance. The amounts of polyester resins and melamine resins in Table 1 were based on solid weight, and the amounts of curing catalysts were represented by weight in terms of the amounts of sulfonic acid compounds.

In accordance with these and other objectives, there is provided a coating composition comprising:. After water was sufficiently removed, the dried cake was dissociated by means of a fluid energy mill to obtain a titanium white a in which the titanium oxide particles were coated with zirconia and alumina.

There is no standard applicable however the film industry and jis k 5400 LCD industry have their own standard regulation to inspect with the load of g based on the jis k 5400 of JIS-K The above oil-free polyester resins generally comprise an esterified compound of a polybasic acid component and a polyhydric alcohol component.

Among the polyester resins mentioned above, the oil-free polyester resins are particularly suitable. With regard to the polyester resin Aif the jis k 5400 average molecular weight is less than about 1, the processing properties may be poor. Most preferably zinc or zinc alloy plated steel plates can be used.

The curing catalyst C is preferably a sulfonic acid compound or a neutralized sulfonic acid compound.

The titanium oxide particles are typically coated with zirconia, alumina and if necessary, titania.
