ANTI FLASH-RUST ADDITIVE
EMADOX®L4 is specifically designed to protect ferrous metals (iron, cast iron, steels), galvanized steels and aluminum in contact with water based formulations.
EMADOX®L4 is a ready to use aqueous solution based on organic corrosion inhibitor salts in combination with sodium nitrite.
EMADOX®L4 is VOC* free.
EMADOX®L4 is frost sensitive. It must be kept at temperature above 0°C.
It is recommended to use EMADOX®L4 within 2 years following its manufacture (see the expiration date on the label).
EMADOX®L4 is mainly recommended for:
flash-rust protection of water based formulations based on acrylic, alkyd, epoxy, polyurethane dispersions or emulsions.
in-can protection for metal packaging filled with above products
EMADOX®L4 must be added preferentially in the letdown, before the rheological agents.
The use in post-addition is also a possible option.
The use levels are:
- typically, from 0.2 to 1% based on the total weight
- exceptionally, for sensitive metal substrates, 1.5 to 2% based on the total weight
There is no advantage to use higher levels. On the contrary, a too high dosage can increase the water sensitivity of the dry film.
