Product Overview
NeXTeRA2435 B
NeXTeRA2435-B is a single-component, solvent-free, low-viscosity, high-expansion, closed-cell hydrophobic polyurethane-urea resin containing MDI and a catalyst package. Designed for use in Pre-Excavation Grouting, it reacts in the presence of water to produce a flexible polyurethane-urea foam, effectively stopping water infiltration in any type of structure. The reaction profile of NeXTeRA2435-B can be adjusted by varying the dose level of NeXTeRACat 2435-B accelerator, making it versatile for diverse grouting applications.
