Problems solved by technology

[0011] For the present invention, the problem to be solved by the present invention is, in such a case, to react a modified silicone oil having a hydroxyl group bonded to a carbon atom with an organic reactive group of a silane coupling agent, and to make the silane coupling The alkoxysilyl group of the coupling agent reacts with the organosilicon alkoxy oligomer, that is, the silane coupling agent is used as an immobilizing agent for both, thereby enabling more firm immobilization

Abstract

The invention provides a vehicle smears used for fixing the vehicle smears of modified organosilicone on a coating surface of the vehicle, preventing the modified organosilicone from periodically dropping from the coating surface, and used for protecting the coating surface. The vehicle smears for protecting the coating surface comprises organosilane alkoxy oligomer, solidified catalyst, silicone oil with molecular having a methyl alcohol modified perssad on any end portion, silane coupling agent and solvent, and a solidified envelope is formed under normal temperature.

Description

technical field [0001] The present invention relates to a coating agent for a vehicle such as an automobile, particularly a vehicle body such as a vehicle body, especially a coating surface of a vehicle body. Background technique [0002] Conventionally, as a coating agent for the surface of a car body, a system in which various properties such as water repellency are improved by adding silicone oil mainly composed of a moisture-curable silicone oligomer modified with an organic functional group has been used. [0003] As such a coating composition, the coating agent for vehicles disclosed in patent document 1 is mentioned. Patent Document 1 discloses a vehicle coating agent characterized by containing a moisture-curable silicone oligomer, a curing catalyst, and a dual-terminal reactive functional group having reactive functional groups at least at both terminals of the molecule. The blending ratio of the silicone oil and the dual-end reactive silicone oil is 25 parts by we...
