| Our actuators are anodized as standard, Wm actuators are blue up to dimension 150 and TT actuators are black. Dimension 250 and 400 are always black due to that the bodies and end caps are casted. Our 180º actuators are delivered in the original aluminum colour, grey. Anodized Anodizing strengthen the natural properties of aluminum by increasing the thickness of the protective oxide layer. The surface keeps its fresh appearance and can be colored in a number of shades. At the same time, the resistance to corrosion and abrasion is increased and the surface becomes dirt-repellent and pleasant to touch. The oxide layer has also electric isolation properties and functions as a good substrate for both printing inks and adhesives. The corrosion resistance is very good, especially in the pH value range from 4 to 9. The surface can be stained and damaged in contact with strongly alkaline substances. Cleaning with water and neutral detergents or white spirit is sufficient. Coating The human eye distinguishes about ten million colour shades. We can avoid mistakes by using the RAL colour chart when talking about different colours. RAL is a world wide standard, used since 1927, with number and name at each colour shade. ANODIZED + POLYESTER POWDER COATING Polyester powder paints now dominate the aluminium architectural paint finish market in Europe and a significant research and development is done in this area. Most paints tend to lose their gloss on exposure to the environment. The standard polyester powder is better than most in this respect «indietro |
