Product Description

TEKAPUR low-expansion foam 750 ml It is used for fixing, gluing and sealing construction elements such as window sills, stairs or decorative laths. Tekapur Low Expansion is a low-expanding one-component polyurethane foam used for fixing, sealing and filling with the help of a gun. Hardens with air humidity. After application, the foam has an extremely low post-expansion and it adheres to the surfaces very well. It enables easy gluing on uneven surfaces as well and it straightens them. The precise application of the foam enables a faster execution of works and economical consumption. Usage: Due to low expansion and good adhesion the foam is used for fixing and sealing various building materials such as wooden stairs and window sills etc. It is also suitable for filling narrow gaps. Precise foam application enables a faster completion of final works and economical consumption.
