aveninject 2c PU-H

Application

• Stabilization of disturbance zone.
• Fastening of anchor injection.
• Hardening of fissured & unstable & petrous of rock & broken rocks.
• Rehabilitation of old sections, Tunnels, Vaults & navigable channels.
• Repair of fixture in concrete.

How To Use it

• If the product has cooled down to low temperatures, it should first be reheated to approx. 15°C. The reaction and curing times are substantially affected by the initial temperatures of the injection resin, the petrous formation and the groundwater.
• In order to ensure the best possible mixing of components during the injection process, it is necessary to use a static mixer at the mixing head, provided with static mixing elements.
• Both components are injected in a 1:1 volume ratio by means of a two-component injection pump. A static mixer combines both components and injects them into the mountain side through an infusion seal.
• Before changing the injected material from PUR resin to silicate-based systems or vice versa, the flexible hoses and the receiving vessel for component A at the pump must absolutely be changed.

Benefits

• Fast-reacting injection system for applications which demand flexibility in addition to high adhesive strength.
• Not recommended as a water blocker. Where necessary, we recommend Avinject 1C 116 EF.
• Permeates into fissure widths over 0.15 mm.
• Reacts and expands in volume without external effects from water.

Packing

The quantities contained in the packaged containers correspond approximately to the dosage ratio of the components (1:1 volumetric).

PURINJECT 2C PU-H is available in the following packaging units:

Component A: 23 kg in 25 | metal container

Component B: 27 kg in 25 | metal container

The different weights of the containers correspond to a volumetric ratio of 1:1 because of the different densities.

Storage

For both components, original unopened containers, when stored in dry areas at temperatures between +5°C and +35°C, When the product has cooled down to low temperatures, it should be reheated to a minimum of 15°C before processing. Component A is susceptible to frost damage. The legal requirements for storage should be observed

Shelf life of 12 months after production

Safety & precautions

• Do not breathe dust/fume/gas/mist/vapor/spray
• In case of improper ventilation wear respiratory protection
• Wear protective gloves/clothing and eye & face protection
• If in eyes: Rinse cautiously with water for several minutes, Remove contact lenses, if present & easy to do. Continue rinse.
• If on skin or Hair: - Take off immediately all contaminated clothing. Rinse skin with water & shower
