Alficoat 748/3 Alficoat 748/3 is identical to Alficoat 748, but a bit more acid. The alternative procedure for the chrome-free "no rinse"-pretreatment of aluminium and aluminium alloys serves as an adhesion base and corrosion protection before powder coating and lacquering. For the application of the product after pre-anodising (ENVIROX PREANO procedure) please refer to the separately available product data sheet.
Alficoat 748/3 produces colourless to slightly yellowish conversion layers.
The system has been approved for application by the international quality
association QUALICOAT (no. A-19) and GSB International (no. 303 a, powder
coating). The ENVIROX “NR”-procedure also succeeded in the 10-year outdoor
exposure test (Hoek van Holland) provided by GSB International.
Alficoat 748/3 produces flawless results in immersion and spraying procedures and is especially suitable for use in coil coating plants and big-volume immersion plants. For the pretreatment of parts which may have retained fluid in indentations, we recommend using Alfipas 745 - Alfipas 746 with the necessary subsequent rinsing.
