TSVES-SP — ethyl silicate pre-fabrication primer (shop primer)

Zinc-rich primers

The TSVES-SP pre-fabrication primer is applied in a single coat on automatic lines at steel fabrication plants and in shipbuilding. It protects the metal for up to 1 year in an open industrial atmosphere, and for the storage period it is suitable for all corrosivity categories per ISO 12944-2. Welding and gas cutting through the single-coat film do not affect the weld quality. It holds an RS type approval certificate; the primer is overcoated with epoxy, polyurethane, vinyl, chlorinated rubber and acrylic materials.
