The present invention relates to a coating composition comprising an organofunctional polysiloxane polymer as a binding resin, obtaining the polymeric structure as part of a curing mechanism or a combination thereof. The main advantage of the invention is that it enables the formation of a flexible inorganic polymeric structure that is more UV-light, heat and oxidation resistant than a coating comprising a large percentage of a carbon based organic polymer.
Description
technical field [0001] The present invention relates to a coating composition or mixture thereof comprising an organofunctional polysiloxane polymer as a binder resin which acquires a polymeric structure as part of the curing mechanism. [0002] A major advantage of the present invention is that it facilitates the formation of a flexible inorganic polymeric structure that is more resistant to UV light, heat and oxidation than coating compositions containing high proportions of organic carbon-based polymeric materials. Background technique [0003] Generally, polysiloxane polymers are considered to be highly resistant to heat, light, and oxidation, but tend to be brittle when applied as a quantitatively three-dimensional crosslinked network. According to the prior art, this problem is solved by mixing more flexible organic polymers in the polysiloxanes. On the other hand, organic polymers generally have poor resistance to heat, ultraviolet light, and oxidation, so that the r...
