NF 304 Crystal Clear NF Polymer

Product Description

NF 304 Crystal Clear NF Polymer is a crystal-clear, elastic adhesive and sealant based on NF Polymer. It is eco-friendly, free from isocyanate, solvents, acids, and halogens. NF 304 is also highly thixotropic, making it suitable for horizontal and vertical applications. It has excellent primerless adhesion to numerous porous and non-porous substrates and exhibits no bubble formation, even in wet and humid conditions. Additionally, it is overpaintable with water-based paints and has no shrinkage.
