This specification covers a French process zinc oxide, raw linseed oil, and alkyd primer suitable for use over blast cleaned steel.
This is an alkyd/linseed oil primer containing 30% more alkyd resin than SSPC Paint 25. It is not recommended for hand cleaned steel.
This primer is suitable for exposures in Environmental Zones 1A (interior, normally dry) and 1B (exterior, normally dry), and is intended for brush, roller, or spray application over steel surfaces prepared in accordance with SSPC-SP 6/NACE No.3, Commercial Blast Cleaning, or SSPC-SP 11, Power Tool Cleaning to Bare Metal, or better. It is suitable as a shop primer, field primer, maintenance primer, or intermediate coat, and is to be applied in accordance with SSPC-PA 1, Shop, Field, and Maintenance Painting of Steel. If the primed part of the structure is to be exposed to the weather, it should be topcoated as soon as practical.
