Surface Cleanliness and Preparation Standards

SSPC-SP2 and SSPC-SP3 for hand and power tool cleaning.

St 2 / SSPC-SP2 (Thorough Hand and Power Tool Cleaning): The surface must be free from visible oil, grease, dirt, mill scale, rust, paint coatings, and any foreign matter when viewed without magnification.

St 3 / SSPC-SP3 (Very Thorough Hand and Power Tool Cleaning): In addition to St 2 requirements, the surface must be abraded to achieve a metallic sheen.

Key Points: Surface roughness or an anchor pattern is not required for adhesion.

For Condensing Lines and Submerged Objects

PIB Wrappingband WSH provides permanent protection against moisture and oxygen, eliminating the possibility of corrosion. It can be used for coated pipelines as a coating repair or on new, bare piping where active lines suffer from condensation, or in environments with high relative humidity.

Polyisobutene (PIB) corrosion prevention is designed for application on wet and submerged structures. An innovative composition enabling application to condensing, damp, or wet surfaces, the product displaces moisture and adheres to the substrate at a molecular level.
