Sikadur 52 Injection Type N
Sikadur 52 Injection Type N is a two part, solvent-free, low viscosity injection-
liquid, based on high strength epoxy resin.
Type N (= Normal Potlife) is used for substrate temperatures between +5°C and +30°C (UK).
As an injection resin with good adhesion to concrete, mortar, stone, steel and wood.
Sikadur 52 Injection Type N 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.
Characteristics / Advantages
- Suitable for both, dry and damp conditions Usable at low temperatures
- Shrinkage free hardening
- High mechanical and adhesive strengths
- Hard but not brittle
- Low viscosity
- Injectable with single component pumps
Mixing ratio A : B = 2 : 1 parts by weight and by volume
Add all of part B to part A. Mix with an electric mixer at slow speed (max. 250 rpm) for at least 3 minutes. Avoid entraining air.
Add both parts in the correct proportion into a suitable clean, dry container and mix in the same way as for the prebatched units.
Application Method / Tools
Saturate a few times using a brush or gravity fill them by pouring mixed ®®
Sikadur 52 Injection Type N between two “dams” e.g. made from Sikaflex
sealant. Cracks penetrating slabs to their soffit should first be sealed on the ®
underside, e.g. with Sikadur -31 epoxy mortar or a suitable cementitious Sika mortar.
Cracks in vertical structures: ®
Mixed Sikadur -52 Injection Type N can be injected under pressure into the cracks using a single component injection pump. Injection ports (packers) are set at approx. 25 cm intervals beside the crack and the crack between the injection ports (packers) sealed e.g. with Sikadur -31 to prevent injection resin to escape during the injection process. Vertical cracks should always be injected from the bottom upwards. As soon as injection resin oozes out of the next packer / injection port, the first one is sealed and the injection process continued from the next one. After completion of the injection process, the injection ports (packers) as well as the sealing material between the ports are removed.
Cleaning of Tools
Clean all tools and application equipment with Sika Thinner C immediately after use. Hardened / cured material can only be mechanically removed.
