PROPERTIES
Form of supply: White powder
Appearance: White, fine Powder
Viscosity of a 10% aqueous acidic solution at 23 °C: mPas. approx,10
(Brookfield viscometer, 60 rpm, spindle No.1)
Dilutability of the 10% solution: unlimited with water
pH of 10% solution at 20 °C: approx. 2.0 (solution acidified with hydrochloric acid)
Density at 20 °C apparent density of the powder: 0.6 – 0.7 g/cm³
Density at 20 °C density of the 10% solution: 1.033-1.037 g/cm³
Ionic character of the 10% acid solution: cationic
MAKS 11058 is readily soluble in warm, acidified water and after short time forms a bluish, opalescent, cationic solution. The resultant solution is ready for direct use and can be metered into the stock. Due to its high cationic character MAKS 11058 is attracted very quickly the cellulosic fibre. The solution has relatively good stability when kept in a closed container and can therefore be kept in stock. MAKS 11058 itself has a low formaldehyde content, thereby reducing undesirable odour during the papermaking process.
MAKS 11058 itself does not yellow and hence does not promote yellowing or greying of paper.
