ASCOTRUST® is a range of innovative, liquid-form, and tannic acid-free rust-converting additives for waterborne coatings, that is ecolabel compliant and VOC free.
ASCOTRUST® additives provide rust-converting properties to the coating layer and enable direct applications on rust or on poorly prepared substrates.
They ensure an efficient rust-blocking effect as soon as the paint is applied and form a passivation layer between the substrate and the coating layer ; this helps to maintain the coating’s anticorrosion performance, despite adverse substrate conditions.
They can be used inside both waterborne clear-coatings and paints.
A waterborne anticorrosion clear-coating containing ASCOTRUST® can be used as a rust-converting pre-treatment which will perform better than tannic acid-based formulations or solventborne alkyd-based oils.
A waterborne metal paint based on ASCOTRUST® provides the following properties :
- Prévention de la “migration” de la rouille à travers le film de peinture, même sur des surfaces fraîchement rouillées.
- Preserving the coating’s color.
- Avoiding strong de-rusting operations before painting, without loss of performance.
- Not compromising the coating anticorrosion performance on non-rusted substrates.
In addition, ASCOTRUST® completes the action of the antiflash-rust additive on very reactive substrates.
