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 是一種雙組份、無溶劑，低粘度高強(qiáng)環(huán)氧樹脂基注漿液。Sikadur-52 可用于其溫度在+5°C 和+30°C 間的基面上。
 
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.
作為一種與混凝土、砂漿、石頭、鋼材和木材有良好粘接性的注漿樹脂，Sikadur-52 被用來填充和密封橋梁和其他土木工程建筑，工業(yè)和民用建筑結(jié)構(gòu)中的空隙和裂縫，例如用于中的柱、梁、基礎(chǔ)、墻、地面和蓄水結(jié)構(gòu)等。它不僅可有效地防止水滲透和腐蝕介質(zhì)的侵蝕，而且可作為混凝土構(gòu)件間的結(jié)構(gòu)粘接劑。
