NF 307 Flexi Sealant

NF 307 Flexi Sealant

Product Description

NF 307 Flexi Sealant is a neutral, highly elastic, one-component NF Polymer-based joint sealant. It is a low modulus sealant suitable for both indoor and outdoor applications. NF 307 is eco-friendly, free from isocyanate, solvent, acids, and halogens. It has excellent primerless adhesion to numerous porous and non-porous substrates. NF 307 exhibits no bubble formation, even in wet and humid conditions. It also has very good UV resistance, is overpaintable with water-based paints, and has no shrinkage.
