FILMFLUX
Additive for flux baths: to save on zinc and improve the quality of the galvanised material.
Phosphor (P), carbon (C) and silicon (Si) are important components in the composition of steels, to guarantee specific mechanical characteristics. In the galvanizing process, the Sandelin curve shows that as the quantity of silicon varies, the iron-zinc alloy increase varies too. At certain silicon values, the increase is very high, causing big problems in terms of coating adherence, as excessive zinc is absorbed, thereby causing hardening and embrittlement of the alloy, and loss of surface brightness.
FILMFLUX is the ideal solution. This liquid additive for the flux bath acts as an inhibitor by reducing the reactivity of the steel.
FILMFLUX: THE ADVANTAGES
- It performs a selective control of the formation of the FeZn alloy (the product is much more active in the presence of Si);
- It improves galvanized-coating brightness at temperatures from 445° to 450°C;
- It improves coating adherence;
- It increases coating elasticity;
- It reduces the formation of drosses;
- It reduces the formation of ashes;
- It improves the flux’s protective function against steel oxidation;
- It is simple to use both in hot and cold fluxes.
