AULA – DATA SHEET FOR COATING MATERIAL AULA KSU 75 Chemical characterization: Mixture of ground coko with clay and binding agents for foundries Supply form: 50, 40, 25kg paper sacks, banded 21,27, 42 sacks for each pallet, stacked, labeled, shrunk with poly-hood Applications: Mould blacking for moulds, cores and ladles in cast-iron foundries and non-ferrous castings and steel factories Coating types: Extursions, flooding, brushing, immersion Purpose: With good properties, an oven distribution of the blacking over the mould is attained, for which a smooth surface is guaranteed. Moreover, a temperature insulation layer occurs between mould and metal, which increases the useful life of the mould (cores/permanent moulds) and makes separation of the casting from the mould (cores/permanent moulds) considerably easier. Chemical analysis: Physical properties: Carbon: 70 - 75 % Ignition loss: 77 - 80 % Ash: 20 - 23 % pH value: 7,0 - 9,0 Sulphur: 0,7 - 0,8 % Bulk density: 700 – 800 g/l Volatiles: 3 - 4 % Odour: none Moisture: 1 - 2 % Coulour: black Processig: 1:1; l.o.:A solution of 1 kg blackingin 1 l water. If necessary use more water External form : dry powder Viskosity: Approx.. 20 sec. Ford-Cup Nr. 4 All given value are made in best knowledge. They are average datas and with tolerances with mineral row materials. We will not give guarantee for the results and the statements which are coming out from the use. We feel however bounded to the prescriptions § 377 HGB GRAPHITE DISPERSION COATING MATERIAL KSU 75 This coating graphite is developed in particular for the use of brass material (but also others) and is highly fire resistant. The use as forming graphite for forms, cores, dies and pans is optimal in the way of spraying, floating, painting and dipping (in cooling bath) possible. The good fluidity and equal distribution to the coating material guarantees the full coating of the total surface which also guarantees a smooth final surface of the castings for the surface treatment to follow. Furthermore a temperature resistant isolation between form and metal lengthening the life time of the dies, forms, cores and facilitates the separation of the casting from the die.
