Monneli Betothane 100

Rigid Polyurethane Injection Resin

Uses
BETOTHANE 100 is a fast reacting polyurethane foam that is mainly used to act as a waterstop for the sealing of leakages or to stop active water leaks with a flow and/or high hydrostatic pressure.
BETOTHANE 100 provides excellent adhesion to mineral construction materials such as concrete, bricks, metals and certain plastics.

Technical Information
Product Description

BETOTHANE 100 is a single component MDI-based water reactive polyurethane injection resin that has a low viscosity when in contact with water forms a temporary hydrophobic seal.

 

BETOTHANE 100 when in contact with water forms a carbon dioxide gas that produces a swelling pressure thus making the resin to expand into foam sealing all water penetration.

Advantages
  • Penetrates even in deep fine cracks
  • Does not shrink after curing
  • Excellent water sealer
  • The reaction speed can be controlled by varying the amount of catalyst
  • Forms a hard sealing with high strength in cracks or joints
  • Does not shrink, therefore volume stays the same
  • Excellent adhesion to concrete
  • Expands up to 2000%
  • Chemically resistant against water, weak acids and alkali, mineral oils, fungus and bacteria, ground water, sea water and petroleum products.

Application Information
Instructions for use

Mixing

Mix Resin (Part A) and the Catalyst (Part B) thoroughly. Inject the mixture with a single component pump (manual, electric, pneumatic) in the crack. Because of the low viscosity, the resin will penetrate deep into the cracks. BETOTHANE 100 polymerizes into a rigid hydrophobic foam.

Cleaning

Clean the used tools with SOLVENTE 10 every time there is a need to stop the work for more than 15 minutes and immediately after completing the job and before the product dries.

Recommendation

  • BETOTHANE 100 could easily react with water or humidity in the air and forms CO2 gas that could build up pressure in the packaging that has been opened.
Additional Information
Health & Safety

Wear gloves, goggles to avoid any contact with eyes and skin. In case of contact in the eyes and skin, wash abundantly with warm water and consult a doctor. Ensure adequate ventilation at working place. 

Absorb spilled resin of BETOTHANE 100 with sand and dispose according to the local regulations.
