Physical Properties of Fluoropolymer Coating: Vinyl must be removed prior to or immediately after installation. These inorganic dyes are much more UV-resistant than the simple immersion metallo-organic dyes used by nearly all anodize jobshops.

Vinyl film may remain on the coating during fabrication and erection. Resources Digital Transformation may be defined in a number of different ways by analysts or enterprise software vendors.

Can someone simply help me see the light on this subject or recommend a proper test specification that I should test to? Promoting, selling, recruiting, coursework and thesis posting is forbidden. Click Here to aetm Eng-Tips and talk with other members!


For best results, cutting edges should be kept sharp, clean, properly dressed and closely aligned. See if they do any exposure testing and if so, what standards they use.

The manufacturer is responsible for technical accuracy. For vehicles, these are standard: After exposure, specimens shall be compared with duplicate specimens not exposed to a light source for the same period of time to determine the Delta E value in asm with ASTM D The Eng-Tips staff will check this out and take appropriate action.

Test specimens, prepared in accordance with 4. Other dye supplier are familiar with Clariant dyes. Maintenance is not required. Technical services are available from Petersen Aluminum Corporation and regional architectural representatives. Delivery time and price will be quoted upon inquiry. Those suitable for architechural include ‘Sanodal’ in the name [Clariant was spun off from Sandoz], e. A strippable vinyl film can be applied for protection during fabrication and installation is desired.

An electrolytic process is then used to change the oxidation states of cation which have entered the anodize pores. I saw that as well Hg, but I’m not sure if the anodizing process would be considered a related coating to paint. Proper bend radii must be used in fabrication.

I’ve been running around in circles, and I hope someone here can help me out. Class 2, dyed anodic coatings, shall show no more fading or discoloration than would be equivalent to a Delta E value of 3 when subjected to the light fastness resistance test see 4.

My company acquired a product line from a company we purchased, and they have specified an architectural anodize process AA-MCA34, Class II, Black for components that are used in the transit industry. The material is tested before and after exposure to these conditions for flammability, mechanical impact and mechanical strength.
