ISO 8504-2 《Preparation of steel substrates before application of paints and related products — Surface preparation methods — Part 2: Abrasive blast-cleaning》 Related products

The ISO 8504-2 "Steel surface preparation before painting - methods of surface preparation - Part 2: sand blasting cleaning" standard specifies sand blasting cleaning as a method of steel surface preparation. Sand blasting cleaning removes oxides, rust, oil and Miscellaneous contaminants by spraying abrasive onto the steel surface using a high voltage airflow to provide a reliable surface condition that ensures coating adhesion and durability. The standard details requirements for sand blasting equipment, operating conditions, sand blasting particle size and cleaning effect evaluation to ensure mass and conformity of steel surface preparation. This method is widely used in steel structures, ships, pipelines and other fields, providing a reliable surface preparation technology for painting engineering and ensuring the long-term performance of the Coating System.
