  • Patent number: 10526438
    Abstract: Method for producing flexographic printing plates from a photopolymerizable flexographic printing plate with a dimensionally stable support, photopolymerizable, relief-forming layer(s), and a digitally imagable layer. The method comprises (a) producing a mask by imaging the digitally imagable layer, (b) exposing the flexographic printing plate with a plurality of UV-LEDs on a UV-LED strip through the mask with actinic light, and photopolymerizing the image regions of the layer, and (c) developing the photopolymerized layer. In the UV-LED strip or in a separate strip, at least one ultrasonic sensor is arranged for determining the thickness of the flexographic printing plate for exposure. Depending on the measured thickness of the flexographic printing plate, the exposing of the flexographic printing plate is controlled in respect of: (i) number of exposure steps, exposure intensity, energy input per exposure step, duration of the individual exposure steps, and/or overall duration of exposure.

  • Patent number: 8609800
    Abstract: Silylated polyurethanes can be manufactured by reacting at least one polyol compound, having a molecular weight from 4000 to 20,000 dalton, with a diisocyanate, with a stoichiometric excess of the diisocyanate compound with respect to the polyol compound or compounds, with the result that a polyurethane prepolymer that is isocyanate-terminated is formed; and by subsequently reacting the polyurethane prepolymer with one or more OH-terminated silanes of formula (1) to yield a polyurethane having predominantly terminal alkoxysilyl groups. In formula (1), m is equal to 0, 1, or 2, R1 is an alkyl residue having 1 to 4 carbon atoms, R2 is an alkyl residue having 1 to 4 carbon atoms, R3 is a divalent organic residue having 1 to 12 atoms, selected from C, N, S, and/or O, in the chain, but by preference exclusively carbon atoms, R4 is a hydrogen atom or an alkyl residue having 1 to 10 carbon atoms, and R is a difunctional organic group, preferably a linear or branched alkyl group having 1 to 6 carbon atoms.
