Patent number: 11186725Abstract: A solvent system is provided, which enables increased amount of exact color tone recipes even when using with currently known dispensing machines having a minimum dispensing limit of 0.01-0.02 ml of a color paste component. The system enables a capability of tinting paints in a tone-accurate manner even into aerosol paint cans of small filling volume. The system provides a capability of radically reducing the amount of various ready-to-use aerosol paints and aerosol base paints stocked by a storekeeper. The disclosure provides an aerosol paint for tinting, as well as a tinted aerosol paint which is suitable for use in a process of mechanized tinting, and by which a good paint coverage on a painted surface is achieved.Type: GrantFiled: March 6, 2018Date of Patent: November 30, 2021Assignee: Wisespray International LtdInventor: Ilkka Parviainen
