Supplementary Notes
Product Features
◆ new environmental protection pretreatment process, no phosphorus, no heavy metals, used to replace the traditional phosphating process.
◆ No water washing, direct drying without water washing after silane conversion, simplified process.
The processing time is short, only 20 seconds to complete the silane conversion film.
◆ Silane conversion bare film rust resistance and iron phosphating (color phosphorus), lower than zinc phosphating (gray phosphorus).
◆ After the silane conversion film only needs to be coated (painting and powder spraying), the coating adhesion and impact resistance are better than phosphating, and the salt spray resistance test of the coating is better than iron phosphating, which is equivalent to zinc phosphating.
◆ can be used for spray or immersion treatment.
