Intergard® 251

For use on properly prepared surfaces in both new construction situations and as an industrial maintenance primer for a wide range of anticorrosive coatings systems for use in the offshore, petrochemical, chemical, pulp, paper and bridge industries.

The fast drying and handling properties, together with extended overcoatability, make this an excellent primer for factory application prior to full system application on site. Intergard 251 provides good abrasion resistance which minimizes mechanical damage in transit between the factory and site. Not designed for continuous water immersion.
