CORROSION TEST
Neutral salt fog =1000 hours no change.
(Din 50021/ASTM B 117-61)
Kesternich test (Din 50018/ISO 3231) = 30 cycles.
Humidostato (Din 50017/ ISO 6270)=1000
hours no change.
Accelerated weathering resistance UV-CON
(ASTM G 53-88)=after 300 hours glass
loss is <50% of the initial value.
The a.m data were obtained on laminates previously prepared with crystaline phosphate of
zinc salt and painted with RAL 9010 series "T 510" . |
CONSPUMTION AND THICKNESS OF THE FILM
Consumption varies according to the thickness of the film , the specific weight of powder
and the working efficency of the application plant. A theoretical yield is therefore
supposable by using the following formula :
