DESCRIPTION
TamPur 130 / TamKat 130 is a single-shot hydrophobic polyurethane based on MDI in combination with polyether polyols and an amine based catalyst. The system only reacts when it comes into contact with water, producing a semi-flexible polyurethane foam.
KEY BENEFITS
- Potable water certified
- Can withstand high hydrostatic pressures
- Variable reaction times
- Semi-flexible
- Reacts with saline and mineral water
- Medium viscosity
- Solvent-free, environmentally safe.
- Sealing against water ingress
- Sealing against leaking cracks and joints
- Sealing against water in masonry and brickwork
- Void filling
- Back grouting

APPLICATION GUIDELINES
TamPur 130 / TamKat 130 is a complete system for void filling and leak sealing in concrete or masonry structures and sandy soils.
Adaptable reaction time is possible by varying the catalyst ratio from between 2% to 10%.
Reaction with water results in the formation of a semi-flexible polyurethane foam which is hydrophobic and chemically resistant. The reaction time can be set from 3 to 14 minutes. (See table of reaction times overleaf.) The pre- mixed resin can be pumped by means of a single component injection pump that is equipped for high pressure. Following the injection, the pump must be thoroughly cleaned with TamPur Cleaner.
Note: Always make sure that the material is homogeneous, mix the resin using a dry clean drill and paddle mixer for a minimum of 15 sec before application.
It is recommended that the material be conditioned to appropriate temperatures for at least 12 hours prior to application.
Important: Keep containers sealed whilst not being used. Moisture may be absorbed into the TamPur from the atmosphere causing it to react. Careful consideration should be given to applications below 10°C on a falling thermometer to avoid possible crystallisation.
STORAGE
TamPur 130 should be stored at room temperature (min 10°C and max 38°C), kept dry and out of direct sunlight. If these conditions are maintained and the product packaging is unopened, then a shelf life of 1 year can be expected.
HEALTH & SAFETY
TamPur 130 should only be used as directed. We always recommend that the Safety data sheet is carefully read prior to application of the material. Our recommendations for protective equipment should be strictly adhered to for your personal protection. The Safety data sheet is available upon request from your local Normet representative.
