    Abstract: The invention relates to a method for preparing a pipe for a continuous spray lining process, the method comprising the following steps: providing an inflatable packer (3); providing an expandable sleeve (4) with a conformable backing layer (5) and an adhesive layer (6); wrapping the expandable sleeve around the packer with the adhesive layer facing the outside; inflating the inflatable packer until it reaches a first diameter (D1), wherein the first diameter is smaller than the inner diameter (d) of the pipe section, thereby expanding the stretching sleeve, inserting the inflated packer with the expanded sleeve into the pipe (1, 2) until it reaches the pipe section to be sealed; and further inflating the packer until it reaches a second diameter (D2), thereby further stretching the expandable sleeve; wherein the second diameter is reached when the expanded sleeve touches the inner diameter (d) of the pipe section.

    Abstract: Provided are reactive compositions for making a polyurethane-based rain-erosion protective coating for rotor blades, the reactive composition comprising an isocyanate-reactive component and an isocyanate-functional component and wherein the isocyanate-reactive component comprises a first component i) being a short chain hydroxyl-functional compound having two terminal (α-ω) hydroxyl groups, a molecular weight of less than 250 g/mole and containing at least 2 carbon atoms and a second component ii) comprising a high molecular weight hydroxyl-functional compound having two terminal (α-ω) hydroxyl groups and a molecular weight of at least 250 g/mol and comprising one or more units selected from oxyalkylene units and polyoxyalkylene units and wherein the isocyanate-functional component is an isocyanate prepolymer of the general formula NCO—Z—NCO, wherein Z is a linking group comprising at least two urethane (—NH—CO—O—) units and additionally one or more units selected from alkylenes, oxyalkylenes, polyoxyalkylenes, alkylene esters, oxyalkylene esters, polyoxyalkylene esters and combinations thereof. Also provided are protective coatings obtained from the reactive compositions and methods of applying the coatings to articles.
