Abstract
A method for producing a coating film, including forming a coating film containing a deposit containing fibers on a surface of an object for forming a coating thereon by an electrostatic spray of a composition. The composition includes component (a) a polymer having a coating film forming ability, (b) one or more volatile substances selected from the group consisting of water, an alcohol and a ketone, and (c) an oil component being liquid at 25° C. and containing a component (c1) one or more selected from the group consisting of oil components having a surface tension at 25° C. of 25 mN/m or less and being liquid at 25° C.
Claims14
A method for producing a coating film, comprising forming a coating film comprising a deposit containing fibers on a surface of an object for forming a coating thereon by an electrostatic spray of a composition comprising the following components (a), (b), and (c):
- (a) a polymer having a coating film forming ability;
- (b) one or more volatile substances selected from the group consisting of water, an alcohol and a ketone;
- and
- (c) an oil component being liquid at 25° C. and containing a component (c1) one or more selected from the group consisting of oil components having a surface tension at 25° C. of 25 mN/m or less and being liquid at 25° C.,
- wherein a content of the component (c1) in the composition is 9% by mass or more and 25% by mass or less, based on a total mass of the composition, and a mass ratio of the component (c1) to the component (c), ((c1)/(c)), is 0.6 or more.
A fiber formable composition for forming a coating film comprising a deposit containing fibers on a surface of an object for forming a coating thereon by an electrostatic spray,
- wherein the fiber formable composition comprises the following components (a), (b), and (c):
- (a) a polymer having a coating film forming ability;
- (b) one or more volatile substances selected from the group consisting of water, an alcohol and a ketone;
- and
- (c) an oil component being liquid at 25° C. and containing a component (c1) one or more selected from the group consisting of oil components having a surface tension at 25° C. of 25 mN/m or less and being liquid at 25° C.,
- wherein a content of the component (c1) in the fiber formable composition is 9% by mass or more and 25% by mass or less, based on total mass of the fiber formable composition, and a mass ratio of the component (c1) to the component (c), ((c1)/(c)), is 0.6 or more.
