The results are shown in Table 3. Highly weather resistant colored steel plate and method for manufacturing the same. The modification degree of a jis k 5400 epoxy modified polyester resin may be such that the amount of the 54000 resin is the range of 0. A neutralized solution of dodecylbenzenesulfonic acid with an amine. From the standpoint of optimizing handling and coating properties, an organic solvent may optionally be added. Examples of suitable neutralizing agents for use in the neutralization of the sulfonic acid compound include basic compounds such as primary amines, secondary amines, tertiary amines, ammonia, caustic soda and caustic potash.
Furthermore, jis k 5400 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 jis k 5400 may optionally be formed using a primer coating film.
A titanium white including a titania jis k 5400 can generally exhibit similar performance to the above described coated titanium oxide. Example 9 The same procedure as in Example 1 was conducted except that any primer was not applied onto an electrically galvanized steel plate having a thickness of 0.
The alkyd resin is preferably a resin that can be prepared, for example, from the acid component of the above oil-free polyester resin, the alcohol component and an oil fatty acid by a known reaction. Then an optical assessment is carried out to see which pencil hardness damages the surface. Thermosetting powder coating composition of an acrylic polymer, dodecanedioic acid, cellulose acetate butyrate and a jis k 5400 agent. Examples of suitable oil fatty acids include coconut oil fatty acid, soybean jis k 5400 fatty acid, linseed oil fatty acid, safflower oil fatty acid, tall oil fatty acid, dehydrated jis k 5400 oil fatty acid and tung oil fatty acid.
Moreover, the present inventors believe that since the methyl etherified melamine resin is preferably present in a relatively high ratio in the inner layer portion, the deterioration of processing properties due to the jis k 5400 etherified melamine resin does not substantially take place.
Next, the particles are preferably coated with alumina so that the coating amount of alumina is preferably in the range of 1. The coating surface on which any shrinkage did not occur and any jis k 5400 defects such as cissing, recesses and clouding were not observed was regarded as good 0. With jis k 5400 to the above blend ratio, if the amount of the polyester resin Jis k 5400 is less than about 65 parts by weight if the amount of the melamine resin curing agent B is more than about 35 parts by weightthe obtained cured coating film may be poor in processing properties and acid resistance.
Melamine Resin Curing Agent B The melamine resin curing agent comprises component B in the composition of the present invention may be a mixed melamine resin of a methyl etherified melamine resin and a butyl jis k 5400 melamine resin. Field of the Invention The present invention generally relates to a coating composition having good coating properties and that is capable of forming a coating film which is jis k 5400 in film hardness, processing property, pollution resistance and acid resistance.
Preparation Example 2 After a hydrate of zirconia was deposited on the surfaces of titanium oxide particles in Preparation Example 1, an aqueous titanium sulfate solution was added to yield about 0. For the thus obtained coated steel plates, various tests were carried out. Typical examples of suitable organic solvents include hydrocarbon solvents such as toluene, xylene and high-boiling petroleum hydrocarbons, ketone solvents such as methyl ethyl ketone, methyl isobutyl ketone, cyclohexanone and isophorone, ester solvents such as ethyl acetate, butyl acetate, ethylene glycol monoethyl ether acetate and diethylene glycol monoethyl ether acetate, alcohol solvents such as methanol, ethanol and butanol, jis k 5400 ether alcohol solvents such as ethylene glycol monoethyl ether, ethylene glycol monobutyl ether and diethylene glycol monobutyl ether.
A coating composition according to claim 1, wherein said hydroxyl group-containing polyester resin is selected from jis k 5400 group consisting of oil-free polyester resins, oil-modified alkyd resins and modified resins thereof. The models differ in load on the pencil tip in grams.
This pencil sharpener complies Test Methods Coating surface appearance: The present invention is described in more detail with reference to examples. The considerable peeling was observed on the coating surface. The noticeable deterioration of the gloss or the noticeable blister was observed. When the curing catalyst is the acid itself, the amount of the acid refers to its actual weight. The number of the reciprocating motions was jis k 5400 until the primer coating film or a steel plate in the case that the primer coating film was not present was exposed.
The coating amount of zirconia is preferably in the range of 0. Therefore, the pollution resistance, which is largely affected by the surface layer portion, can be improved by the butyl etherified melamine resin.
For jis k 5400, a rutile crystalline titanium jis k 5400 material having a primary particle diameter of about 0. A coating composition according to claim 1, wherein the number average molecular weight of component A is from 5, to 25, A cellophane adhesive tape was stuck on the surface of the cut test plate, and it was then abruptly peeled therefrom.

The 500 trace was considerably observed. US USA en Twenty pencils from grade 9B to 9H are used with a standard holder Pencils are moved over the surface under a fixed pressure and jis k 5400 fixed angle — ensuring the least amount of operator error Pencils can jis k 5400 easily exchanged to minimize down time during the test.
The above oil-free polyester resins generally comprise an esterified compound of a polybasic acid component and a polyhydric alcohol component. For example, roll coating, curtain flow coating, immersion coating or spray coating can be employed. A coating composition according to claim 1, wherein said sulfonic acid compound is selected from the group consisting of p-toluenesulfonic acid, dodecylbenzenesulfonic acid, dinonylnaphthalenesulfonic acid and dinonylnaphthalenedisulfonic acid.
Thereafter, a hydrate of zirconia can be deposited on the surfaces of the titanium oxide particles. Jjs jis k 5400 to conventional precoated steel plates used in the manufacture of the vessels, characteristics such as pollution resistance and acid resistance in addition to the hardness and the processing property have recently been regarded as important. A titanium white, which has been subjected to the jis k 5400 coating treatment, has an alumina coating layer present as the outer layer.
This is jis k 5400 the compatibility of the melamine resin with the polyester resin A is optimized under these conditions, and the pollution resistance and processing property of the obtained coating film are also benefitted. At this time, the remaining ink trace was evaluated by the naked eye.
Datasheet pdf User Manual pdf. Blocking resistance generally refers to the strength of the coating when subjected to acid or other such agent. A coated metal plate according to claim 23, wherein the coating composition is formed uis a metal plate using a primer.
Crosslinking in the coating jis k 5400 may be jia out, for example, mainly by using a methyl etherified melamine resin, so that optimum jis k 5400 properties of the coating film can also be maintained.
