Angle test piece with a nick. 6. Specimen preparation in accordance with EN 13486: neither cut nor blended. Test temperature +100°C, leaching time 0.5 hours as specified in the standard for product maximum service temperature. 7. The coupons from type 304 stainless steel sheet, 1.5 mm thick. 28 days drip test using deionized or distilled water at around +100 °C. 8. For environmental conditions outside the given range please contact our Customer Service Centre. 9. During storage of the product, blooming on the surfaces may occur, especially at wall thickness below 19 mm. This blooming does not affect the technical properties of the material, but can affect the adhesion properties. Therefore, the surface needs to be cleaned before adhesives can be applied. 10. For further information and application instructions please contact our Customer Service Centre. 11. Shelf life (maximum storage time) is limited in order to make sure that only currently manufactured products are applied on projects. This limitation is restricted solely to storage of the product and does not affect the lifetime of product after it has been installed.
