The present invention relates to a two-component system comprising a component A) comprising at least one polymeric polyol which has an OH content of &#x2264;4.5 wt %, based on the total solids content of the polymeric polyol, and a component B) comprising at least one polyisocyanate which has a number average isocyanate group functionality of &#x2265;4.0 to &#x2264;10.0, based on the total solids content of the polyisocyanate, a fraction of &#x2264;25 wt %, based on the total solids content of the polyisocyanate, of oligomers containing isocyanate groups and having a number-average molecular weight of &#x2264;780 g/mol, and an isocyanurate group fraction of &#x2265;5 mol % to &#x2264;70 mol %, based on the total amount of isocyanurate groups and allophanate groups in the polyisocyanate. The invention further relates to a method for producing a coating on a substrate, to the coating obtainable by this method, and to the coated substrate.

Two-component system for elastic coatings

A silty floating mud collection device, which includes a drive cylinder, an outer sleeve, a sampler barrel, an lug cover plate, a turning cover, a control ring and a control rod, where the drive cylinder includes a cylinder liner, a piston and a piston rod; the outer sleeve is fixedly connected below the cylinder liner; the sampler barrel is detachably installed inside the outer sleeve; the lug cover plate is fixedly connected to a lower end of the piston rod, and can close an upper-end opening of the sampler barrel; the turning cover is turnably installed at a lower end of the outer sleeve, and can close a lower-end opening of the sampler barrel; the control ring is located below the sampler barrel, and is used to block the turning cover which is in an open state; and an upper end of the control rod is connected to the lug cover plate, and a lower end of the control rod is connected to the control ring.
