Technical Information Shore A Hardness ~24 (after 28 days) | (ISO 868) |
Secant Tensile Modulus ~0.40 N/mm2 at 100% elongation (23 °C) | (ISO 8339) | ~0.60 N/mm2 at 100% elongation (−20 °C) | |
Tear Propagation Resistance Service Temperature −40 °C to +90 °C Joint Design The joint width must be designed to suit the movement capability of the sealant. The joint width shall be ≥ 10 mm and ≤ 35 mm. A width to depth ratio of 2:1 must be maintained. Standard joint widths for joints between concrete elements
Joint distance [m] | Min. joint width [mm] | Min. joint depth [mm] | 2 | 10 | 10 | 4 | 15 | 10 | 6 | 20 | 10 | 8 | 30 | 15 | 10 | 35 | 17 |
All joints must be correctly designed and dimensioned in accordance with the relevant standards, before their construction. The basis for calculation of the necessary joint widths are the type of structure and its dimensions, the technical values of the adjacent building materials and the joint sealing material, as well as the specific exposure of the building and the joints. For larger joints please contact our Technical Service Department. |
