Product Description

Hempel 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.

Best Uses

Hempadur Avantguard 550 functions as a zinc-rich epoxy featuring a higher mechanical strength. Can utilize ASTM D520, type II zinc dust. Hempel Hempadur Avantguard 550 is ideal as a versatile primer for long-term protection of steel in severely corrosive environments.

  • 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


Remove oil and grease etc. thoroughly with suitable detergent. Remove salts and other contaminants by high pressure fresh water cleaning. Abrasive blasting to Sa 2½ (ISO 8501-1:2007), SSPC-SP 10/ NACE No. 2, with a sharp-edged surface profile corresponding to Rugotest No. 3, BN10a-b, Keane-Tator Comparator, 3.0 G/S, 2-3 S, or ISO Comparator, Medium (G). See application instructions data sheet.

Use only where application and curing can proceed at temperatures above: -10°C/14°F. Maximum application temperature is 40°C/105°F. Maximum relative humidity: 95%. Special attention should be made to the prevailing temperature and RH trend to ensure that conditions are within the acceptable range throughout the application and drying time. The temperature of paint itself should be 15°C/59°F or above. Apply only on a dry and clean surface with a temperature above the dew point to avoid condensation. In confined spaces provide adequate ventilation during application and drying.

Before mixing with the curing agent stir the base thoroughly in order to re-disperse any possible settling after storage. After mixing it is equally important to maintain stirring to keep the wet paint as a homogeneous mixture. This is specifically important in case of a high level of thinning and/or long break in application, where
the risk of settlement of zinc particles is the highest.
