Definitions
- the present invention relates to a method for producing scratch-resistant coatings, in particular scratch-resistant
- the present invention also relates to coating compositions suitable for this process
- This article proposes to increase the scratch resistance of the clearcoat coatings by incorporating siloxane macromonomers, since these siloxane macromonomers lead to an increased homogeneity of the clearcoat surface and above 60 ° C. to an improved plastic flow.
- EP-A-540 884 discloses a process for the production of multi-layer coatings, in particular in the motor vehicle sector, using free-radically and / or cationically polymerizable, silicone-containing clearcoats, in which the clearcoat is applied when illuminated with light of a wavelength of more than 550 nm or in the absence of light and then the clearcoat layer by means of high-energy
- EP-A-568 967 also discloses a process for producing multi-layer coatings, in particular in the motor vehicle sector, using radiation-curable clearcoats. According to EP-A-568 967, however, it is essential to the invention that, in order to achieve clear lacquer layers with a high optical quality, first a thermally curing clear lacquer and then a radiation-curable clear lacquer are applied.
- the present invention is therefore based on the object of providing a method for producing scratch-resistant coatings.
- the coating agents used in this process should at the same time have good storage stability (at least 8 weeks when stored at 50 ° C.) and lead to coatings which, at the same time, have high chemical resistance, good moisture resistance and good polishability in addition to the high scratch resistance.
- These coating compositions should also be suitable as clearcoat and / or topcoat for producing a multi-layer coating, in particular in the motor vehicle sector.
- the cured coating compositions should have good weather resistance, good acid / base resistance and good resistance to bird droppings, etc., high gloss and good appearance.
- the objective assessment of the scratch resistance of the hardened coating should be possible based on physical parameters, regardless of the test method selected. This method should be practically applicable for determining the physical parameters and should enable the character of the scratch resistance to be characterized as adequately as possible with sufficient accuracy.
- a method for producing scratch-resistant coatings which is characterized in that a coating agent is used which, after curing, has a storage module E 'in the rubber-elastic range of at least 10 " ° " Pa and a loss factor tan ⁇ at 20 ° C has a maximum of 0, 10, the memory module E 'and the loss factor tan ⁇ using the dynamic mechanical thermal analysis homogeneous free films with a layer thickness of 40 + 10 ⁇ m have been measured.
- the present application also relates to the use of the process for producing a multilayer coating and to coating compositions suitable for this process.
- DMTA dynamic mechanical thermal analysis
- lacquers which have only a medium or even a small plastic portion at the test temperature, but which have a very high storage modulus in the rubber-elastic range, nevertheless produce coatings with a high scratch resistance. It is particularly advantageous that these coating compositions according to the invention lead to coatings which, in addition to the high scratch resistance, have good polishability, good moisture resistance, good weather resistance, good chemical and acid / base resistance and a high gloss. Furthermore, the coating compositions according to the invention have a good storage stability of 8 weeks when stored at 50 ° C.
- the coating agent is selected so that the cured coating compositions in the gurnrnielastischen area has a storage modulus E 'of at least 10 ⁇ 6 p a preferably at least 10 8> ° Pa, particularly preferably at least l ⁇ 8,3 p a un ( j has a loss factor at 20 ° C.
- the loss factor tan ⁇ is defined as the quotient of the loss module E "and the storage module E '.
- Dynamic mechanical thermal analysis is a generally known measurement method for determining the viscoelastic properties of coatings and is described, for example, in Murayama, T., Dynamic Mechanical Analysis of Polymeric Material, Esevier, New York, 1978 and Loren W. Hill, Journal of Coatings Technology, Vol. 64, No. 808, May 1992, pages 31 to 33.
- the measurements can be carried out, for example, using the MK II, MK III or MK IV devices from Rheometrics Scientific.
- the storage module E 'and the loss factor tan ⁇ are measured on homogeneous free films.
- the free films are produced in a known manner by applying and curing the coating agent on substrates to which the coating agent does not adhere. Glass, Teflon and in particular polypropylene may be mentioned as examples of suitable substrates. Polypropylene has the
- the layer thickness of the free films used for the measurement is generally 40 + 10 ⁇ m.
- the special selection of the coating compositions based on the value of the storage module in the rubber-elastic range and the loss factor at 20 ° C. of the cured coating compositions enables the provision of Coating agents with the desired property profile of good scratch resistance with good polishability, chemical and moisture resistance as well as weather resistance, since both parameters can be determined by simple DMTA measurements.
- the resulting coatings also have a high gloss and an acid and base resistance that is comparable to the corresponding values of conventional, thermally hardened paints.
- lacquers which have only a medium or even a small plastic component at the test temperature, but which have a high to very high storage modulus in the rubber-elastic range, also give coatings with a high scratch resistance
