- the present invention relates to the field of catalysis of crosslinking reactions between polymer chains, e.g. silicones, comprising reactive radicals capable of forming interchain bridging, so as to obtain a crosslinked material having a certain hardness and a certain mechanical strength.
- polymer chains e.g. silicones
- reactive radicals capable of forming interchain bridging
- substrates A are intended to react with substrates of type B having, per molecule, at least one reactive unsaturated aliphatic group and / or at least one reactive function, eg epoxide, in the presence of a catalyst comprising at least one platinum complex, such a reaction being initiated or activated by light rays, of wavelength, chosen, preferably, in the field of ultraviolet (UV).
- UV ultraviolet
- the present invention relates, first of all, to new catalytic systems formed by photoactive organoplatinic complexes in the crosslinking by hydrosilylation of polyorganosiloxanes A of Si-H type and of compounds B with aliphatic unsaturation and / or with reactive function. .
- the present invention also relates to a hydrosilylation process in which the above-mentioned catalytic systems are used, as well as compositions which can be crosslinked by photoactivation and which contain, inter alia, the substrates A and B and the above-mentioned catalyst.
- coatings formed from a mixture of silicone oils which can be crosslinked together and which are intended to form non-stick layers on fibrous supports such as paper, dental impressions, adhesives, sealants, jointing materials, etc.
- non-stick paper application among others, cross-linking in situ by photoactivation, eg by UV irradiation, is particularly advantageous insofar as it allows high coating speeds.
- this in situ crosslinking can take place easily at room temperature. It also avoids the use of solvents, the elimination of which is costly and difficult.
- these catalysts are in the form of organometallic complexes (platinum or the like).
- platinum has proven to be the most suitable metal for entering into the composition of these organometallic complexes.
- the source of the platinum in this solution is formed by the catalyst of SPEIER or hexachloroplatinic acid.
- This KARSTEDT catalyst has the drawback of not being part of the photoactivatable hydrosilylation catalysts.
- the activation adapted to this KARSTEDT catalyst is thermoactivation, which is, all the same, much more restrictive and expensive than a simple UV activation, of the type of that targeted by the invention.
- Another major defect of the catalyst of the KARSTEDT solution is that it has a relatively poor storage stability (gel time at 25 ° C less than or equal to 1 min).
- Another objective of the invention is to provide a hydrosilylation process by photoactivation of reactive products, and in particular of silicones, in which the abovementioned catalytic systems are used, said process having to be easy to carry out, fast, and inexpensive.
