Abstract
A method for treating coating film is provided, whereby a window glass can be securely bonded to a substrate, even when the substrate has been furnished with a hydrophilized coating film. Before bonding a window glass 14 to a clear top-coat coating film 7 which contains a silicate compound as a hydrophilizing agent, with using a window glass adhesive 16 as an organic adhesive, the clear top-coat coating film 7 is coated with a body primer which contains an organic reactive group reactable with an organic resin and which contains an additive 13 formable a covalent bonds CB with the silicate compound in the clear top-coat coating film 7.
Claims8
A method for treating coating film which contains a hydrophilizing agent, to be conducted before an object is bonded to the coating film with an organic adhesive, which comprises a step of applying a primer to the coating film, wherein
- said primer has an organic reactive group reactable with organic elements, and contains an additive formable a covalent bond with the hydrophilizing agent in the coating film.
A method for treating coating film which contains a hydrophilizing agent, to be conducted before an object is bonded to the coating film with an organic adhesive, which comprises a step of applying a primer to the coating film, wherein
- said hydrophilizing agent in the coating films is an organosilane compound, and
- said primer has an organic reactive group reactable with organic elements, and contains an organosilane compound as an additive.
A method for treating coating film, to be conducted before an object is bonded to the coating film with an organic adhesive, which comprises a step of applying a primer to the coating film, wherein
- said primer is composed of a first primer which has an organic reactive group reactable with organic elements, and contains an organosilane compound as an additive, and a second primer which has an organic reactive group reactable with organic elements, and contains no organosilane compound.
