ISOFOAM LF is a rapid setting, two-component hydrophobic polyurethane foam. When cured, ISOFOAM LF is a rigid closed cell structural foam which resists moisture and vapor transmission. ISOFOAM LF is acceptable for use in floors subject to USDA and FDA inspection and regulation.
Advantages
- 100% CFC/HCFC-Free
- Actively uses subgrade materials in cured structure
- Fast cure; can be handled/walked on in less than 1 hour
- Has a medium viscosity to allow for easier injection and better penetration into narrow voids below slab
- High compression strength
- Insensitive to grade moisture from water infiltration of scrubbing operations
