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 μm and 2.0 μm and the other type of less than 1.0 μm. A mixing ratio of the two types of hard solid-state particles lies in the range from 1.5:1 to 1:1.5.
