High-Quality PU-25 Sealant
Sealants & Silicones
Application and Areas of Use It has excellent adhesion to cement-based building materials, brick, ceramic, glass, wood, galvanised sheet, painted sheet and many plastic surfaces. In the construction sector it is used to fill the joints between building elements. It is used in laying roof tiles and in mounting PVC window frames. In the installation of wooden doors and windows, it is used to fill the gaps left between the wall and the frame. It is used as a sealing agent at the joints of prefabricated building elements and rainwater collection pipes on roofs, and in rain gutters. In buildings, it is used to close the working allowances left open between precast concrete blocks.
