Definitions
- Liquid, radiation-curable coating compound for coating glass surfaces Liquid, radiation-curable coating compound for coating glass surfaces
- the present invention relates to a liquid, radiation-curable coating composition for the coating of glass surfaces, containing
- the present invention also relates to a method for coating glass surfaces, in particular optical glass fibers, using these radiation-curable coating compositions.
- Optical glass fibers have become increasingly important in the field of communication as optical fibers. For this purpose, it is absolutely necessary to protect the glass surface from moisture and wear and tear. The glass fibers are therefore provided with a protective lacquer layer immediately after their manufacture.
- the two-layer structure should ensure good protection of the glass fibers against mechanical stress even at low temperatures.
- EP-B-114 982 radiation-curable coating compositions based on a diethylenically terminated polyurethane, a diethylenically unsaturated ester of a diglycidyl ether of a bisphenol and a monoethylenically unsaturated monomer, the glass transition temperature of the homopolymer produced from this monomer being above 55 ° C.
- EP-B-33043 discloses radiation-curable coating compositions based on vinyl monomers and reactive polymers (no polyurethanes), it being essential to the invention that either the vinyl monomers or the polymers have a thiirane ring to add organiosilanes as adhesion promoters.
- suitable compounds are ⁇ -aminopropyltriethoxysilane, N, ⁇ -aminoethyl- ⁇ -aminopropyltrimethoxisilane and ⁇ -glycidyloxypropyltrimethoxisilane. This document does not deal with the problem of loss of adhesion of the glass fiber coatings when exposed to moisture.
- JP-PS-45 138/85 from October 8, 1985 (corresponds to JP-OS 42 244/80 from March 25, 1980) to use organosilanes as adhesion promoters in radiation-curable glass fiber coating compositions.
- Polymers with azide groups are used as the film-forming component.
- Suitable silanes are ⁇ -methacrylic oxypropyltrimethoxysilanes, ⁇ -aminopropyltrimethoxysilane and ⁇ -glycidyloxypropyltrimethoxysilane.
- Essential to the invention in JP-PS 45 138 is the incorporation of the azide groups into the polymers, so as to increase the curing rate. The problem of the influence of moisture on the adhesion of the glass fiber coating is therefore not dealt with in this document either.
- EP-A-149 741 discloses liquid, radiation-curable glass fiber coating compositions which, in addition to a radiation-curable, polyethylenically unsaturated polymeric compound, contain 0.5 to 5%, based on the coating composition of a polyalkoxysilane.
- Such polyalkoxisila are suitable ne which carry an organic substituent which carries a single active amino or mercaptyl hydrogen atom which can react in a Michael addition with the ethylenically unsaturated bonds.
- X-mercaptopropyltrimethoxysilane is mentioned as an example of suitable silanes. According to the teaching of EP-A-149741, it is only possible to improve the adhesion even when exposed to moisture by using such silanes.
- These radiation-curable coating compositions are characterized by good adhesion of the coatings to glass surfaces, even when exposed to moisture.
- the object of the present invention was to provide radiation-curable coating compositions for the coating of glass surfaces, in particular optical glass fibers, in which the resulting coating, after exposure to moisture, has little or no loss of adhesion in comparison with the corresponding freshly produced coating and has the coating examined immediately after curing.
- these radiation-curable coating compositions must be clear, so as to ensure the lowest possible attenuation loss in relation to the irradiated intensity of information when used as a coating agent for optical glass fibers.
- the object on which the invention is based is achieved by a liquid, radiation-curable coating composition for the coating of glass surfaces which A) contains 56 to 89% by weight of at least one diethylenically unsaturated polyurethane which may contain urea groups,
- component B one or more carboxyl-containing, ethylenically unsaturated monomers, optionally together with other ethylenically unsaturated monomers and
- component D an epoxy group-containing alkoxysilane is used.
- the present invention also relates to a method for coating a glass surface using the coating compositions according to the invention, an optical glass fiber coated with the coating compositions according to the invention and the use of these optical glass fibers as optical waveguides.
- adhesion promoters In view of the large number of organosilicon compounds known as adhesion promoters, it was surprising and unpredictable that precisely through the combined use of alkoxy silanes containing epoxy groups and the use of carboxyl-containing ethylenically unsaturated monomers, possibly in combination with other ethylenically unsaturated monomers as reactive diluents (component B) Adhesion of radiation-curable coating agents based on unsaturated polyurethanes on glass surfaces at all or not at all when exposed to moisture
- Alkoxysilanes such as ⁇ -glycidyloxypropyltrimethoxisilane, i.e. without the use of carboxyl group-containing ethylenically unsaturated monomers as reactive thinners when exposed to moisture, the adhesion deteriorates considerably.
- the radiation-curable coating compositions according to the invention also have the advantage that these coating compositions are clear and thus, when used as a coating agent for optical glass fibers, ensure the lowest possible loss of attenuation with respect to the irradiated intensity of information.
