Hempadur Avantguard 550

Description

Hempadur Avantguard 550 is an activated zinc epoxy primer in compliance with the requirements of Level 3, type II in SSPC Paint-20, 2019. Hempadur Avantguard 550 functions as a zinc-rich epoxy featuring a higher mechanical strength. The product is in full compliance with ASTM D520 type II and EU Directive 2004/42/EC, the Paints Directive on the limitation of volatile organic compounds: subcategory j.

Recommended use

Hempadur Avantguard 550 is recommended as a versatile primer for long-term protection of steel in severely corrosive environments.

The most economical activated zinc primer

Avantguard 550 is a zinc epoxy primer (level 3 in SSPC – 65%) that leverages Hempel’s patented Avantguard® technology. It performs at the same level as conventional zinc rich primers (80% of zinc) and Level 2 in SSPC. It meets test requirements up to C5-VH making it a suitable alternative to nominal zinc-rich primers, with an anticorrosive performance on par or better than many traditional 80% zinc-rich epoxies.

Superior steel protection with Avantguard

Enhanced corrosion protection text in white on a blue background

Triple activation technology

In standard epoxy coatings, a simple barrier prevents the steel substrate from interacting with the environment. Avantguard utilises three methods of corrosion protection: barrier effect, galvanic effect and inhibitor effect. Avantguard 550 is a cost-effective solution offering these three methods of corrosion protection with an optimized zinc content.

Improved sustainability

Avantguard technology’s enhanced zinc activation optimises zinc utilisationwithout compromising corrosion protection. Avantguard 550 is a zinc primer (level 3 in SSPC – 65%) which performs on the same level as a zinc-rich primer (according to ISO 12944-5) whilst delivering up to 18% less CO²e (embodied).
