摘要:
The invention relates to solids which contain; (i) on average, at least two groups (a) having at least one bond per molecule that can be activated by actinic radiation, whereby the groups (a) are structurally different from one another and are bound to the base structure of the solid via urethane groups or contain; (ii) on average, more than one group (a) with at least one bond per molecule that can be activated by actinic radiation, whereby the groups are structurally different from one another or identical, and they can are bound to the base structure of the solid via urethane groups, and contain; 0.01 to 1 mol %, with regard to the existing bonds that can be activated by actinic radiation, of at least one chemically bound polymerization inhibitor (b). The inventive solids can be produced by reacting the starting products in the molten mass. The invention also relates to the use of the solids as coating substances, adhesives or as sealing compounds or for producing the same, to coating substances, adhesives or sealing compounds that can be produced by using the solids, and to coatings, adhesive layers or seals that can be produced from the coating substances, adhesives or as sealing compounds.
摘要:
The invention relates to a method for producing a coated substrate by applying at least one coating agent to the substrate and then hardening said coating agent in order to obtain a coat of lacquer on the substrate. The invention also relates to the coated substrates obtained by said method, and a coating agent.
摘要:
The invention relates to a method for producing scratch-resistant coatings. The inventive method comprises the following steps: applying at least one coating means that can be hardened by UV radiation to at least one surface of an object to be coated, whereby the coating means comprises at least one polymer and/or oligomer P1 with, on average, at least one ethylenically unsaturated double bond per molecule, hardening the coating means under the influence of UV radiation. The inventive method is characterised in that the coating means is hardened in an oxygen-containing protective gas which is provided with an oxygen partial pressure ranging from 0.2 to 18 kPa.
