Описание:

A two component epoxy anti-corrosive primer pigmented with zinc phosphate.
INTENDED USES: For use on properly prepared surfaces in both new construction situations and as an industrial
maintenance primer for a wide range of anti-corrosive coatings systems for use in the offshore, petrochemical, chemical, pulp and 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 minimises mechanical damage in transit between the factory and site.

 

Surface preparation:

All surfaces to be coated should be clean, dry and free from contamination. Prior to paint application all surfaces should be assessed and treated in accordance with ISO 8504:2000. Oil or grease should be removed in accordance with SSPC-SP1 solvent cleaning.

Abrasive Blast Cleaning
Abrasive blast clean to Sa2½ (ISO 8501-1:2007) or SSPC-SP6. If oxidation has occurred between blasting and application of Intergard 251, the surface should be reblasted to the specified visual standard. Surface defects revealed by the blast cleaning process should be ground, filled, or treated in the appropriate manner.
Surface profile must be a minimum of 50 microns (2 mils).

Shop Primed Steelwork
Weld seams and damaged areas should be cleaned to a minimum St3 (ISO 8501-1:2007) or SSPC -SP3. Optimum performance will be achieved with blasting to Sa2½ (ISO 8501-1:2007) or SSPC-SP6; where this is not practical, hand preparation to SSPC-SP11 is recommended. If the shop primer shows extensive or widely scattered breakdown overall sweep blasting may be necessary.
