GENERAL INFORMATION
Black A Patinal® is a light grey powder mixture suitable to produce dark-brown to black low reflectance layers on glass and plastics. Black A layers appear brownish in transmission, i.e., not black. The name Black A originates from the original application in the 80’s where it was used for dark sunglasses with blackish appearance. The Black A layers are hard, adhesive and resistant against humid air (90 % humidity at 35 °C) and salt solutions (4 % NaCl in water at 25 °C). They are not affected by temperature (8 hours at 360 °C in air).
