In order to obtain such an effect satisfactorily, when the component A is 100 parts by mass, the curing catalyst for the component B is 0.1 to 40 parts by mass.

The moisture-curable liquid silicone oligomer of component A is a liquid silicone oligomer of KC89S, KR213, KR400, KR401, KR401N, KR500, KR510, KR9218, X-40-2308, X-40-2327 from Shin-Etsu Chemical Co., , X-40-2651, X-40-9225, X-40-9227, X-40-9238, X-40-9247, X-40-9250, X-41-1053, X-41-1056, X -41-1805, X-41-1810, GE XC96-B0446 from Toshiba Silicones, SR2402, AY42-161, AY42-163, AY42-182, AZ from Toray Dow Corning Co., -6101, SILRES MSE 100, SILICATE TES 40 WN from Asahi Chemical Industry Co., Ltd., and the like are suitable and preferable examples.

The urethane-coated steel sheet was made by the following application method. That is, the SPCC steel sheet (general cold rolled steel sheet) obtained by degreasing the two-component curing type urethane paint made by Nippon Paint Co., Ltd. with isopropyl alcohol and then with a petroleum solvent was used as the white stain resistance, And baked at 100 DEG C for 2 hours to prepare a urethane-coated iron plate. A degreasing operation was carried out by spraying uniformly a special degreasing agent on the surface of the urethane-coated steel plate, wiping off immediately, and wiping with a special cloth. Subsequently, the degreased clean surface was uniformly hand painted with a dedicated sponge for the surface water repellent protective agent for external scene described in Tables 1 and 2 or applied uniformly on the degreased surface using a low-pressure air gun and dried . Immediately after drying, the excess polymer (polymer) was wiped with a cloth for cleaning only and the surface was smoothed. In either case, an initial evaluation was performed after one day of curing at 25 ° C.

After curing at 25 占 폚 for 2 weeks, an inverse model test was carried out using a cleaning liquid diluted 50 times with neutral car shampoo by the method specified in JIS K5400. After the surface was washed 5,000 times with a brush, the remaining water droplets were lightly pressed and absorbed with paper, and then tap water was applied to the surface, and the water repellency was generally protected by the naked eye. And those markedly deteriorated were evaluated as?. Furthermore, the test piece was fixed to the exposure test bench by the method specified in JIS K 2396, and the outdoor exposure test was performed for 3 months. After that, the surface was washed, washed with water and wiped with a neutral car shampoo diluted 50 times, Water was applied and evaluated visually. A " indicates that the water repellency is generally maintained, and " " indicates that the water repellency is maintained rather than the uncoated surface but is clearly lower than that at the initial stage. After 2 weeks of curing at 25 占 폚, the carbon black powder was uniformly dispersed on the surface, maintained at 50 占 폚 for 2 hours, cleaned with neutral car-shampoo, and the surface thereof was observed for contamination resistance test. The clear surface was rated as?, The clearness was almost clear but the slight black contamination remained, and the clear black contamination remained.

As a result of these tests, it was found that the spread of the liquid in Example 10 was worse than that in the Examples slightly different from those in Example 10, and that there was a slight unevenness in the degree of visibility in Examples 9 and 10 Except for this, the embodiment of the present invention was good in both the application with the dedicated sponge and the application with the air gun. On the other hand, in Comparative Example 5, Comparative Example 5 had a poor wiping sound after drying and poor appearance, and Comparative Example 7 also had bad appearance due to unevenness of application at the time of spraying and poor leveling property thereafter. In Comparative Example 2, there was almost no improvement in the contact angle of the surface due to appearance-free construction. For these three examples, no further evaluation was performed. Further, in Comparative Example 4, the spread of the liquid was slightly poor, and a slight uneven appearance was recognized.

In the stain resistance, in Examples 1 and 10, only good results were obtained, and the remaining Examples 2 to 9 were excellent. On the other hand, Comparative Examples 1, 3 and 4 and Comparative Example 6 were good in the comparative example and Comparative Example 8 was excellent in the good.

In the present invention, Examples 1 and 5, 8, 9 and 10 were good in the Examples, and the remaining Examples 2 to 4 and 6 and 7 were excellent. On the other hand, in the comparative examples, all were poor.

In the case of the weather resistance, Example 1 was good in Example 1, but the other Examples 2 to 10 were excellent in ⊚. On the other hand, in Comparative Example 4, Comparative Example 4 was good and Comparative Example 8 was good, but Comparative Examples 1, 3, and 6 were poor.

As described above, in Examples 1 to 8 of the present invention, excellent stain resistance, gas resistance and weather resistance as well as excellent appearance were obtained, and a favorable appearance without coating unevenness was obtained, and a strong film having excellent durability against car wash It can be formed. Also in Examples 9 and 10, it was found that a strong film excellent in durability, gas-resistance and weatherability as well as excellent in durability against washing, there was. On the contrary, in Comparative Examples 1 to 8, none of the three points of stain resistance, resistance to weather, and weather resistance were excellent.

Further, the surface water repellent protective composition of the present invention and the composition of the comparative example are coated and cured on the painted surface of the automobile loop to improve the initial gloss and water repellency, and the effect on the front window glass caused by the rainwater flowing from the roof due to the subsequent rainfall Respectively.

First, five compact cars of each maker of black metallic paint within three years from the registration of the new car were prepared, and polishing was carried out using a non-silicon compound in all five loops, (Oil content) was removed. Water and oil were removed from the front window glass using a commercially available strong oil film remover. Water repellent protective compositions D1, D6 and D7 shown as Examples 11 to 13 in Table 5, and compositions H4 and H6 in Comparative Examples 9 to 10 as Comparative Examples 9 to 10 were used in the same application method as Tables 3 and 4, After curing for about 20 hours in the room adjusted to about 25 캜 by an air-conditioner, the initial gloss and water repellency of the applied surface were visually evaluated and confirmed to be all good. Also compositions D1, D6 and D7, and H4 and H6 are the same compositions as those of Table 1 and Tables 3 and 4.

Then, while the wiper was operated by hanging the engine from the car wash, the water was continuously poured in a shower state for 30 minutes so that about 10 L of tap water flowed from the rear of the loop toward the front window glass in one minute by using a watering hose. Thereafter, the glass state of the front window was immediately observed, and the presence or absence of flashing due to adhesion of the oil film was visually evaluated as sparkling property. The results are shown in Table 5. In this evaluation, " ⊚ " indicates that no glare was hardly observed on the front window glass surface, and " Good " Moreover, x is defined as a clear glare.

In Examples 11 to 13, there was no problem in the front window glass because there was no glare, and the visual field remained good. On the other hand, in any of Examples 9 to 10, a glare was felt on the front window glass. The reason for this is that in the composition H4 of Comparative Example 9, the value of C / A x 100, which is the amount of the component C used for the component A, is 153.85, and the amount of the component C relative to 100 parts by weight of the component A exceeds 25 parts by mass Out of the unreacted component in the C component. On the other hand, in the composition H6 of Comparative Example 10, there is no water repellency imparting agent for component C, and since it is substituted by KF96-500 cs which is a non-reactive water repellency imparting agent silicone oil, flashing occurs.
