  • Publication number: 20230304941
    Abstract: The invention relates to a method for providing a system for assessing a coated surface with respect to a type set containing at least one type of surface defect that can occur on the surface, to such a system for assessing a coated surface, to a measuring device for acquiring an image of a coated surface including such a system, and to a method for assessing a coated surface using such a system. The system can use a convolutional neural network (CNN), in particular the so-called U-Net architecture, to recognize the at least one surface defect in an image provided to the system. Moreover, the system can use a support vector machine algorithm to provide, based on the recognition results, quantitative and/or qualitative information about the depiction of the at least one surface defect in the image provided to the system.

  • Patent number: 8501880
    Abstract: A polymer obtainable by free-radical polymerization of one or more oxetane-based macromonomers and optionally one or more further, free-radically polymerizable comonomers, the oxetane-based macromonomer(s) being obtainable by cationic ring-opening polymerization of at least one hydroxyoxetane with a terminally ethylenically unsaturated starter molecule free of allyl groups in a molar ratio (hydroxyoxetane(s):starter molecule) of (100:1) to (1:1) in the presence of at least one suitable catalyst. Processes for preparing the polymer and the use thereof as an additive in coating compositions and plastics.

  • Patent number: 8486188
    Abstract: The invention relates to a method for production of polyhydroxyfunctional polysiloxanes with branched polyglycidol polyether groups, in which firstly at least one allylic or methallylic starting material is reacted with at least one glycidol, such that an allyl polyether or methallyl polyether is formed, and then the allyl polyether or methallyl polyether thus produced is added to a Si—H functional alkyl polysiloxane in the presence of an acid buffering agent. The invention further relates to polysiloxanes, which may be obtained by said method and the use of the polysiloxanes in coating agents, polymeric coating masses and thermoplastics.
