This can be a vague term, but usually hardcoat refers to a very thick and hard anodic coating. This kind of anodizing is accomplished with a bath similar to the standard sulfuric process, but with the temperature reduced to about…
A conversion coating is a chemical treatment applied to aluminum. It is sometimes known as “passivating”, “chrome phosphate” or “alodine.” Chrome-free conversion coatings are now available. This is usually done prior to painting or applying an adhesive, and is accomplished by immersing…
Mechanical contact must be made with each part that is painted. The heavier a part is, the more mechanical contact required.
If you have an application where electrical conductivity is important, you should test an actual production run for this characteristic. You should also make sure that the anodizer knows this is a design parameter for your application. The dielectric strength…
Depending on the applied weather barrier and water proofing requirements, silicone may not be required for sealing cornice joints. However, it is recommended.
Definitely. Submit your desired gutter profile for review and an SAF Perimeter Systems Gutter Pro will provide full details.
Typically, yes. Hardware is included with our Commercial Gutter, Gravel stop and Copings systems as quoted. However, we do not supply hardware for our Commercial Cornice and Gutter Downspout Wall Bracket attachments. In these cases, attachment hardware options may be available…
Yes. Anodized aluminum is often used on cookware. (However, FDA approval depends on the anodizer and on the process. SAF is not FDA approved on any of our anodizing processes.) In contrast to the electroplating process, it is not difficult…
Yes. According to the Aluminum Extruder’s Council, alloys 6061, 6105 and 6063 are best suited to painted applications. Since painting is obviously quite different from anodizing, keep your metal supplier informed of your finishing requirements. This will result in better…
PVDF surfaces are not a good choice for UV or UV screen printing. PVDF is made to be extremely chemical resistant and additional coatings will not adhere well, even with pre-treatment and cleaning. Polyester surfaces will work better for UV…
