Single-component, solvent-free polyurethane injection resin is ideally suited to cut off water in wet cracks and scratches of reinforced concrete structures. The reaction with water forms a semi-rigid polyurethane foam. The resin can be injected using a mono-injection pump.
Reaction with water creates a flexible polyurethane foam with closed cells..
The reaction rate can be easily adjusted by changing the catalyst content from 6% to 10%. The more that is added to the catalyst, the sooner the reaction. PURINJECT 1C FLEX is very hygroscopic and packed in dry atmosphere. Open containers should be used as soon as possible. Injection Pumps should be cleaned with a dissolving material such as polyurethane. PURCLEAN is a product designed specifically for cleaning polyurethane injection pumps To avoid problems, it is very important to understand that the materials are sensitive to moisture and temperature. Therefore, materials should be stored at a temperature not exceeding 30 ° C and not less than 10 ° C.
