Sikadur-52
Sikadur-52 is two parts, solvent-free, low viscosity injection-liquid, based on high strength epoxy resin. It is used for substrate temperatures between +5°C and +30°C.
Sikadur-52 是一种双组份、无溶剂，低粘度高强环氧树脂基注浆液。Sikadur-52 可用于其温度在+5°C 和+30°C 间的基面上。
Use
用途
As an injection resin with good adhesion to concrete, mortar, stone, steel and wood, Sikadur-52 is used to fill and seal voids and cracks in structures such as bridges and other civil engineering buildings, industrial and residential buildings, e.g. columns, beams, foundations, walls, floors and water retaining structures. It not only forms an effective barrier against water infiltration and corrosion promoting media, but it also structurally bonds the concrete sections together.
作为一种与混凝土、砂浆、石头、钢材和木材有良好粘接性的注浆树脂，Sikadur-52 被用来填充和密封桥梁和其他土木工程建筑，工业和民用建筑结构中的空隙和裂缝，例如用于中的柱、梁、基础、墙、地面和蓄水结构等。它不仅可有效地防止水渗透和腐蚀介质的侵蚀，而且可作为混凝土构件间的结构粘接剂。
