130026/0179130026/0179
Polyvinylchlorid 100 TeilePolyvinyl chloride 100 parts
glimmerartiges Aluminiumpulver 5 bis 70 "mica-like aluminum powder 5 to 70 "
Metallpulver 0 bis 14-5 "Metal powder 0 to 14-5 "
Weichmacher falls erforderlichPlasticizer if necessary
Stabilisator falls erforderlichStabilizer if necessary
Die Gesamtmenge an glimmerartigem Aluminiumpulver und anderem Metallpulver soll 150 Teile nicht überschreiten.The total amount of micaceous aluminum powder and others Metal powder should not exceed 150 parts.
Die Verwendung von weniger als 5 Teilen glimmerartigem Aluminiumpulver ist unerwünscht, weil in diesem Fall die Beschichtung eine schlechtere Wetterbeständigkeit und Korrosionsfestigkeit zeigt. Mengen von mehr als 70 Teilen sind ebenfalls unerwünscht, da in diesem Fall die Beschichtung sich schlechter verformen läßt. Eine Gesamtmenge der Metallpulver von mehr als 150 Teilen ist unerwünscht, da das beschichtete Blech sich schlechter verformen läßt. Der Weichmacher und Stabilisator wird in solchen Mengen zugesetzt, daß eine gute Verformbarkeit und Haltbarkeit der Beschichtung bzw. des beschichteten Blechs sichergestellt ist.The use of less than 5 parts of micaceous aluminum powder is undesirable because in this case the coating has inferior weather resistance and corrosion resistance shows. Quantities in excess of 70 parts are also undesirable because in this case the coating is more difficult to deform. A total amount of the metal powders in excess of 150 parts is undesirable because the coated Sheet metal is more difficult to deform. The plasticizer and stabilizer are added in such amounts that a good deformability and durability of the coating or the coated sheet is ensured.
