  • PARTICULATE COMPOSITION FOR PRODUCTION OF LOW-WEAR NONSTICK COATINGS, AND COATED PRODUCT
    Publication number: 20240124722
    Abstract: A composition for producing particulate coatings for printing machine cylinders or printing machine cylinder covers that are nonstick and wear resistant. The composition includes at least one sol-gel precursor compound and a mixture of hard solid-state particles, such as silicon carbide. One type of particles has a Sauter diameter d32 of between 1.0 ?m and 2.0 ?m and the other type of less than 1.0 ?m. A mixing ratio of the two types of hard solid-state particles lies in the range from 1.5:1 to 1:1.5.

  • Cylinder jacket profile, method of producing an easy-clean layer on a cylinder jacket profile and printing press
    Patent number: 6766738
    Abstract: A cylinder jacket profile for impression cylinders or sheet transfer cylinders has uniformly distributed elevations with an easy-clean layer as a surface coating. The easy-clean layer has a thickness of less than 5 &mgr;m, in particular 1 &mgr;m, and a surface energy of less than 50 mN/m. The cylinder jacket profile has an improved cleaning behavior. A method of producing an easy-clean layer on a cylinder jacket profile is also provided.
