PROFFLEX A is a one-component acrylate sealant with high vapor permeability. The sealant is designed to perform the outer layer of the assembly joint in accordance with DSTU-N B V.2.6-146:2010 with an allowable deformation of the assembly joint of no more than 15% for sealing the outer contour of window, door and balcony structures. High-quality acrylic sealant PROFFLEX has properties and is designed for wrapping slopes on windows, doors and balcony blocks, from the outside,
