HEMPADUR AvantGuard 550 is a two-component, activated zinc epoxy primer in compliance with the requirements for Level 3, type II in SSPC Paint 20, 2002. HEMPADUR AvantGuard 550 functions as a zinc-rich epoxy featuring a higher mechanical strength.Can utilize ASTM D520, type II zinc dust.

Recommended use:

As a versatile primer for long-term protection of steel in severely corrosive environments.

Features:

• Reduces the effect of corrosion and offers excellent protection
• Good mechanical strength, also in cyclic temperatures, with improved crack resistance through high flexibility and self-healing of micro cracks
• High tolerance to different climatic conditions (high temperature and humidity) during application, as well as, to high dry film thickness
