The polyurethane assembly foam for contact with drinking water is an assembly and insulating polyurethane material that is formed when a reactive liquid mixture foams and cures as it interacts with moisture in the air. It is specially formulated for applications in which direct contact with drinking water is anticipated.
Primary applications of the polyurethane foam for contact with drinking water include insulating well rings, water pipelines, sewers, waste channels and other structures.
Store in a dry and well-ventilated location at +5°C to +25°C. The guaranteed effectiveness of the product is within 18 months of manufacture.
The polyurethane foam meets the requirements for permanent contact with drinking water: see report No. 32100/2011 from 27 Dec. 2011 issued by Zdravotní ústav se sídlem v Plzni (Pilsen institute of health and hygiene) (test laboratory no. 1384).
Always read the safety warning before use. This information is only a recommendation based on our experience. Try the product first!
- The surface can be wet prior to application. However, it should not be covered with frost or ice.
- The optimum ambient temperature for foam application is from +15°C to +20°C. Shake the contents of the bottle vigorously for one minute. The temperature of the contents of the bottle should never differ from the ambient temperature by more than 5°C. Ensure never to exceed the permitted foam processing temperature range of +0°C to +35°C.
- Screw the plastic dispensing adapter onto the valve of the bottle. The working position of the bottle is upside down. The amount of foam released is controlled by squeezing the dispensing adapter lever. The quality and volume of hardened foam depends on the relative air humidity. Use a spray bottle filled with water to moisten the space in which the foam will be applied. If the average size of the gap is more than 5 cm, fill only part of the space — the layer thickness should be max. 2 cm. Moisten the freshly applied foam and continue to layer the foam until the space is filled. The foam expands as it cures, meaning only 1/3 of the space should be filled initially. If the relative air humidity is less than 35%, add large amounts of moisture to the foam.
- Hardened foam can be cut using a cutter. The surface must be protected against prolonged exposure to UV radiation.
- Fresh foam can be removed using a PU cleaner. Cured foam can only be removed using mechanical aids. If the work is interrupted for more than 10-15 minutes, the applicator must be cleaned with a PU cleaner.
