Abstract: The invention relates to novel antimicrobial surfactants and their application in antimicrobial coating systems, in particular water borne coatings. Provided is a method for providing an antimicrobial surfactant, comprising the steps of: (a) providing a hyperbranched polyurea having blocked isocyanates at the end of the polymer branches by the polycondensation of AB2 monomers; (b) introducing tertiary amine groups by reacting said blocked isocyanates of the hyperbranched polyurea with a tertiary amine compound that is functionalized with —OH, —NH2, —SH, or —COO—; and (c) quaternization of said tertiary amine groups by reacting with an alkylating agent to obtain a quaternized hyperbranched polymer having antimicrobial surfactant properties.

Abstract: A process for coating of a substrate is provided, comprising: (a) applying a first layer of a liquid solvent-free UV-curable primer coating composition to a substrate surface; (b) curing the first layer UV irradiation; (c) optionally applying and curing additional layers of a liquid solvent-free UV-curable coating composition; (d) providing a granular material, having an average particle size of 60-600 mm, to the coating; (e) applying a final layer of a liquid solvent-free UV-curable finisher coating composition; and (f) curing the final layer by irradiation with UV light. The coating compositions comprise 20-90 wt % UV-curable resin, 5-70 wt % filler, 0.1-10 wt % photoinitiator and less than 5 wt % solvent, based on total weight of the coating compositions.

Abstract: The present invention relates to a freight container comprising a frame (10); an attachment point (20, 21, 22, 23) for a lifting device to attach to the container; and a wall, roof or floor comprising: an impact resistant portion (30, 30?) proximal to the attachment point; and a portion (100,100?), distal from the attachment point. The impact resistant portion (30, 30?) has an impact energy resistance of at least 1.0 kilojoules and the modulus of elasticity of the distal portion (100,100?) is at least 20% greater than the modulus of elasticity of the impact resistant portion.
