AB RUST® NFC
ANTI FLASH-RUST ADDITIVE
AB RUST®NFC is specifically designed to protect metal in contact with water based formulations.
AB RUST®NFC is a ready to use aqueous solution made of organic based corrosion inhibitors.
AB RUST®NFC is VOC* free, nitrite free and European Ecolabel* compliant.
AB RUST®NFC is able to resist at temperature below 0°C. The solidification point is less than -15°C.
It is recommended to use AB RUST®NFC within 2 years following its manufacture (see the expiration date on the label).
AB RUST®NFC is mainly recommended for:
flash-rust protection of water based anticorrosive primers, paints and varnishes based on acrylic, styrene-acrylic, alkyd, epoxy, polyurethane dispersions or emulsions
in-can protection for metal packaging filled with above products
AB RUST®NFC 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 0.5 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.
