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.

System and method for assessing a coated surface with respect to surface defects

The invention relates to a polymer having a) a polymer backbone and b) one or more polymeric side chains covalently linked to the polymer backbone, wherein the polymeric side chains comprise a polyether segment and a polysiloxane segment, said polysiloxane segment having a number average molecular weight in the range of 1050 to 6000, and said polyether segment being positioned between the polymer backbone and the polysiloxane segment.

Polymer having polyether and polysiloxane segments

The invention relates to copolymers obtainable from polyether-polysiloxane containing macromonomers, and a process for preparation thereof. The invention further relates to the use of the copolymers as additives in compositions such as coating compositions and polymeric molding compounds as well as such compositions containing at least one inventive copolymer.

Copolymers containing polyether-polysiloxane macromonomer units, process of their preparation and their use in coating compositions and polymeric moulding compounds

The present invention relates to the use of modified polysiloxanes in thermally curing coating material compositions and molding materials, and to thermally curing coating material compositions and molding materials comprising modified polysiloxanes. The present invention also relates to coatings on a substrate, and to moldings which have been produced with such a coating material composition or molding material.

Use of modified polysiloxanes in coating material compositions and molding materials

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.

Polymers obtainable from oxetane based macromonomers, method for the production thereof, and the use thereof as additives in coating agents and plastics

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&#x2014;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.
