PROCESS FOR TREATING THE SURFACE OF A TRANSPARENT LAYER HAVING ANTI-TEARING PROPERTIES |
摘要 |
<p>A process for the treatment of the surface of a transparent sheet or film having antilacerative and self-healing properties and the product made thereby, wherein the sheet or film includes a thermosetting polyurethane material employed as an external layer on a laminated glass or laminated plastic sheet or a mixture thereof. The process involves depositing a solution, dispersion or emulsion of wax or a wax-like substance and a silicone oil; or a solution, dispersion or emulsion of wax or a wax-like substance, a silicone oil and a fine-grained polishing agent on the surface of the polyurethane material. The solvent or solvents for the wax or wax-like substances have a boiling range of 40 DEG to 300 DEG C., and the silicone oil is present in an amount of less than 4% by wt. when no polishing agents are present and in an amount of from about 2 to 10% by wt. when fine-grained polishing agents are present. The product made by the process has been rendered particularly resistant to scratching and abrasion without formation of striations on the surface.</p> |
