Publication number: 20230143725Abstract: Disclosed herein is an aqueous coating composition containing an aqueous epoxy resin dispersion, an aqueous amine-functional resin dispersion and an aromatic carboxylic acid. The aqueous dispersion contains at least one specific di- and/or polyfunctional monomeric amine and at least one resin component including at least one specific polyfunctional organic amine. Further disclosed herein is a kit-of-parts including a base varnish containing the aqueous epoxy resin dispersion and a curing component containing the aqueous amine-functional resin dispersion as well as the aromatic carboxylic acid. Additionally disclosed herein is a process for producing a coating on the substrate as well as coated substrates resulting from said process. Cured coating layers formed from said compositions exhibit a good adhesion to the substrate as well as a high intercoat adhesion and blistering stability under humidity conditions without negatively influencing the excellent sandability and the good stone chipping properties.Type: ApplicationFiled: March 17, 2021Publication date: May 11, 2023Inventors: Anna KONDRAT, Egbert NIENHAUS, Joerg RESSEL, Karin WEVER, Silke PRZYBILLA, Tim VOEGELING, Sibylle SCHOEPS

Patent number: 10525491Abstract: Provided herein is a safety and control device for pressure vessels for application devices for liquid media including a safety valve, a control device for the operating pressure, a pressure indicator, and a pressure relief, as well as a means for connecting the device to the pressure vessel, the device having a housing, which is provided with a compressed air supply and an air outlet, and a multifunctional slide arranged within the housing. The multifunctional slide defines a channel, which is connected to a blind bore and a pin and at the end has means for relieving the pressure by manual actuation. A spiral spring encloses a pin and supports the multifunctional slide with respect to a bottom of the housing. Locking means enable the pin to be arrested in a position protruding from the housing.Type: GrantFiled: May 11, 2016Date of Patent: January 7, 2020Assignee: BASF Coatings GmbHInventors: Philipp Moews, Andreas Schroeer, Sibylle Schoeps, Roland Meisner

Patent number: 10464086Abstract: A metering and mixing device contains a multichamber cartridge and a cartridge holder having a reception container for the multichamber cartridge and a compressed air connection and a connection for an application device. The reception container has an internal tube arranged coaxially to the walls of the cartridge holder and equipped with static mixing elements. The multichamber cartridge contains an upper portion having a directional valve, a middle portion configured as a tubular empty space surrounded by at least two chambers arranged tubularly in the direction of the longitudinal axis of the cartridge, and a lower portion having a piston for each chamber. The multichamber cartridge is arranged in the cartridge holder such that the inner wall of the inner tube of the multichamber cartridge bears, leak-tight, against the outer wall of the tube of the cartridge holder.Type: GrantFiled: July 6, 2015Date of Patent: November 5, 2019Assignee: BASF Coatings GmbHInventors: Sibylle Schoeps, Thomas Krueger, Joachim Vosskuhl, Roland Andreas Meisner, Ernst Schneider
