ASCOTRUST®
Rust Converting Additives
ASCOTRUST® rust converter additives trap ferrous cations and react with them to form stable complexes, chemically bonded onto the metal substrate. This immobilisation stops rust-migration through the film. These products are typically used in aqueous pigmented coatings.
Unlike tannic acid based technologies, ASCOTRUST® is compatible with a wide range of binders and doesn't adversely affect the colour or anti-corrosion performance of the coating.
They display excellent synergy with ASCOTRAN® anti-flash rust inhibitors and ASCONIUM® anti-corrosion additives. All products are easy to incorporate, VOC-free and Ecolabel compliant. Dosage is in the range of 1.0-5.0 wt %, depending on the specifics of the formulation and substrate.
