3. The coated film according to claim 1, wherein the (meth)acrylate (A) is a polyfunctional (meth)acrylate.
4. The coated film according to claim 1, wherein a content of the (meth)acrylate (A) in the coating solution is 5 to 95% by weight, and a content of the crosslinking agent (B) in the coating solution is 5 to 95% by weight, both based on a total amount of whole non-volatile components in the coating solution.
5. The coated film according to claim 1, wherein the coating solution further comprises particles having an average particle diameter of not more than 1.0 \u03bcm, and a content of the particles in the coating solution is not more than 25% by weight based on a total amount of whole non-volatile components in the coating solution.
6. The coated film according to claim 1, which is used for forming a surface functional layer from a solvent-free active energy ray-curable resin on a surface of the coating layer.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A method of injecting a sealing gel into a predetermined structure for a work piece, comprising steps of:
providing a molding tool with an insertion structure shaped with respect to compliment the predetermined structure;
enclosing a local region of a recess of the work piece with the molding tool;
injecting a fluid sealing gel into the molding tool; and
dismantling the molding tool after the sealing gel has cooled to a solid state.
2. The method according to claim 1, wherein the work piece has a box shaped body.
3. The method according to claim 2, wherein the recess is disposed along a top surface of a side wall of the box shaped body.
4. The method according to claim 3, wherein the predetermined structure includes a vertical slot extending along a height of the side wall.
5. The method according to claim 4, wherein the insertion structure includes a vertical rib corresponding to the vertical slot.
6. The method according to claim 5, wherein the molding tool includes an outside plate fittable with an outside surface of the side wall at the local region.
7. The method according to claim 6, wherein the molding tool further includes an inside plate fittable with an inside surface of the side wall at the local region.
8. The method according to claim 7, wherein the molding tool further includes a top cover plate covering a top surface of the outside plate.
9. The method according to claim 8, wherein the top cover plate covers a top surface of the inside plate.
10. The method according to claim 9, wherein the molding tool further includes an injection port passing through the top cover plate and communicating with an inside chamber thereof.
11. The method according to claim 10, wherein the fluid sealing gel is injected into the inside chamber of the molding tool through the injection port.
12. The method according to claim 8, wherein the top cover plate includes a vent hole.
13. The method according to claim 8, wherein the insertion structure is formed on at least one of the outside plate, the inside plate, and the top cover plate.
14. The method according to claim 1, further comprising the step of:
injecting a second sealing gel about an exposed recess in an open injection manner.
15. The method according to claim 1, wherein the sealing gel has a fluid state.
16. The method according to claim 1, wherein the sealing gel is a thermoplastic.
17. The method according to claim 15, further comprising the step of:
injecting the fluid sealing gel through a nozzle and into the recess.
18. The method according to claim 17, further comprising a gel supply container disposed before the nozzle.
19. The method according to claim 18, wherein the gel supply container includes a heater to convert the sealing gel into the fluid state and a pump pushing the fluid sealing gel to the nozzle.
20. The method according to claim 19, wherein the pump is a speed adjustable pump.
21. The method according to claim 20, further comprising an additional heater provided on the nozzle.
22. The method according to claim 21, wherein injection of the sealing gel is performed by a multi-freedom robot having an end effector on which the nozzle is mounted.
23. The method according to claim 1, wherein the work piece is disposed on a positioning platform before injecting the sealing gel.
