PRODUCT DESCRIPTION:
MC-Injekt 1260 is two-component Epoxy-based injection resin for repair applications. MC-Injekt 1260 is used to repair dry structures in various types of concrete to prevent water and contaminants.
PRODUCT PROPERTIES:
- Low-viscosity, epoxy-based duromer resin.
- High penetration activity.
- Fast hardening.
- Cures well under conditions of displacement.
AREAS OF APPLICATION:
- Filling and restoring the bearing capacity of cracked structures, technical gaps, and voids of construction works in dry conditions by pumping or permeation pouring.
- Safety criteria when evaluating according to REACH: Safe in case of accidental inhalation during pumping.

AREAS OF APPLICATION:
- Preparation: Before pumping, it is necessary to check the condition of cracks and defects of the structure according to standards and technical regulations. Then prepare a suitable pumping treatment plan and method.
- Mixing:
– MC-Injekt 1260 consists of two components. The components A and B have to be mixed according to recommended ratio using slowly rotating stirrers until the mixture is homogenous.
– Before processing, the mixed reactive resin has to be repotted into a clean empty container or a container in which only mixed resin of the same quality was stored and shortly remixed. Repotting is fulfilled when the resin is poured into the reservoir of an injection pump and remixed thoroughly.
– The application time depends on the quantity of the mixed material and the ambient temperature. After mixing the amount of resin is to be devided or cooled to extend the application time.
– It is recommended to mix only cool resin components completely and to portion the resin in two to three equal subsets to minimize reactive heating. - Application:
– MC-Injekt 1260 can be executed with the injection pump MC-I 510 (one-component pump).
– The choice of the suitable injection packer depends on the injection pressure. MC-Klebepacker or MC-Hammerpacker are recommended for an average pressure range (up to 60 bar).
– For injection with high injection pressure (up to 200 bar), MC-Injektionspacker DS 14 can be used.
– Work with MC-Injekt 1260 must be stopped if the temperature of the structure drops below +8°C. - Cleaning tools and equipments: Within the application time, all tools can be cleaned with MC-Verdunnung EP (MC-Thinner EP). Partially or completely cured material can only be removed mechanically.
