CEMTEX ELASTIC INJECTOR

CEMTEX ELASTIC INJECTOR

Price available upon request.

Two components product, mixed once together. They are ready to react with water and swell to grout joints or repair leaking. Reaction can be controlled by the percentage of accelerator.

Product / Service Details

Description

Cemtex Elastic Injector is a hydrophobic grout based on a MDI (methylene-diphenyl-isocyanate)  polyurethane.The resin is 100% solvent free and 100% solids. The

gel-time of the product is adjustable by adding a certain percentage of Cemtex Elastic Injector accelerator (10% ).

Upon contact with water, Cemtex Elastic Injector reacts to flexible closed cell rubber-like foam while expanding its volume up to 15 times. The cured flexible material is of a constant volume. Since water is not a component of the foam structure, the cured material is essentially not affected by water or dryness. The reacted material does not shrink or swell. Depending on the amount of accelerator added and the pressure of injection, Cemtex Elastic Injector reacts to a very dense and flexible material onto flexible foam.

Cemtex Elastic Injector is approved for drinking water contact.

Cemtex Elastic Injector is extremely well suited to seal against water in moist and wet joints and cracks in concrete. The material offers high flexibility and elongation properties combined with good adhesion on wet and dry concrete surfaces.

Cemtex Elastic Injector is a product of the cemtex polyurethane injection resin line. In order to achieve best results, a combination of several products may be recommended in some applications

Applications

  • Sealant for infiltrating water through:
  • Defective Concrete (Cracked or Honeycombed)
  • Concrete Construction Joints
  • Expansion joints
  • Moving cracks
  • Limestone
  • Brick Construction
  • Pipe Intrusions
  • Waste Water Tanks
  • Drinking Water Reservoirs
  • Sewers, Manholes, Utility

Processing

  • Cemtex Elastic Injector and Cemtex Elastic Injector Accelerator are supplied separately to allow adjustment of gel-time and to provide a long shelf life. The CEMTEX Accelerator System has been proven to be far superior over the solvent-loaded single component materials.
  • Subsequently the technician is able to determine gel-time and reactive properties of the material, which allows him to adjust to critical situations on the jobsite.
  • In high pressure water-instructing, the system will react aggressively on contact and quickly stop the flow when catalyzed at 10. A slightly catalyzed product at 2, on the other hand assures good penetration results in super fine capillary crack injection.
  • A mixing ratio between 50:1 and 10:1 Cemtex Elastic Injector accelarator is recommended. This translates into a concentration between 2 and 10 of accelerator in the mixture. 10 is the standard mixing ratio.
  • Observe temperature and humidity of the environment since both determine the pot-life of

the premixed batch.

  • Do not mix more material than the amount that will be pumped within reasonable time.
  • Rule: High temperatures and high humidity –less accelerator.
  • Due to the low viscosity, the foaming process and the high-pressure injection, Cemtex Elastic Injector penetrates even into small cracks.
  • Since Cemtex Elastic Injector reacts with the moisture in the structure, single component injection equipment is recommended.
  • Hydrophobic grouts do not need large amounts of water for the reaction unlike hydrophilic materials.
  • Simultaneous injection of water is not necessary.
  • If the area of application seems to be dry, pre-injection of water is recommended.
  • It is essential for all equipment to be dry. Avoid any moisture contact with the mixture to prevent premature reaction of the product.
  • If a reaction of the batch occurs while pumping, shut down the machine immediately and flush with a cleaner to avoid built up and clogging of the equipment.

Maintenance of equipment

  • Remove all excess sealant and any smears.
  • Tools and mixing equipment are best cleaned immediately after use.
  • Cemtex cleaner can be used – if it is not in conflict with regulations on job site.
  • Circulate cleaner through pump for several minutes.
  • Caution! Some cleaners are combustible.

Precautions

  • While working with BYGGING INTERCONTINENTAL products; safety, goggles, gloves and safety clothing should be worn at all working times.
  • Also observe container labels, MSDS, and instructions in the BYGGING INTERCONTINENTAL Product Catalog.
  • In case one of the components comes in contact with the skin, wash thoroughly with soap and water.
  • Adequate ventilation in volume and pattern should be provided in working area.

•Further protection: Emergency showers and eyewash stations
