Cemflex PU525 is a high-performance fast curing single component polyurethane sealant. When cured it will form a tough and flexible seal and its bond is capable of cyclic, expansion, and compression movement. Joints or fabrications formed with this sealant can be expected to extend and compress a total of 50% (± 25%) of original joint dimensions. Cemflex PU525 withstands normal weathering conditions such as rain, sunlight, snow, sleet, ultra-violet radiation, ozone, atmospheric contamination, and pollution.  Its excellent weather ability enables it to retain its original properties after years of exposure. Its physical properties remain relatively unchanged over a wide temperature range (-35ºC to 80ºC).
