Anti set-off powders of the K4plus series are inorganic, mineral based products made of natural calcium carbonate. The single particles get a rounded shape by a special manufacturing process. Particular surface properties are also achieved with a complex process, such as optimum feeling and excellent gliding characteristics. Anti set-off powders of the K4plus series are insensitive against ordinary humidity and are neither soluble in water nor in alcohol.
Due to its high specific gravity K4plus is especially dust depleted and economical in application. The formation of dust in the delivery and around the press can be reduced to a minimum. Anti set-off powders of the K4plus series can be sprayed very regularly, are not hygroscopic and not sensitive to static charges.
With our anti set-off powders of the K4plus series we offer through our graduations 15, 20, 30 and 45 the suitable grain size for any paper grammage.
Anti set-off powders of the K4plus series are controlled continuously and fulfil the requirements of the German industry wide agreement of low-dust anti set-off powders.
