Abstract: The present invention relates to a device and a procedure for the quality control of in particular finished surfaces wherein the device comprises at least one illuminating means having at least one light source, its light directed at a predetermined angle to the measurement surface. A plurality of at least three measuring means is provided, whereby each of said measuring means is directed at a different predetermined angle to the measurement surface and receives a portion of the light reflected from said measurement surface. Each measuring means comprises at least one photosensor which emits an electrical measurement signal which is characteristic of the light received by said measuring means. A control and evaluation means having at least one processor means and one memory means controls the measurement sequence, evaluates the measurement results and derives therefrom a parameter which characterizes the surface. An output means serves for the outputting of parameters or measurement results.
Abstract: The invention relates to a process for preparing a solution which comprises urea urethanes and is effective as a thixotropic agent, which involves reacting at least two structurally different monohydroxy compounds with an excess of toluene diisocyanate to form monoisocyanate adducts, removing the unreacted portion of the toluene diisocyanate, and reacting the resultant monoisocyanate adducts with diamines in an aprotic solvent in the presence of a lithium salt to form urea urethanes. The invention also relates to the use of the solution to receive thixotropic coating compositions.
