SOPRASEAL LM 204 VP is a low-odor, vaporpermeable polyether air barrier with 98% solids content. The 1-component monolithic membrane is fully adhered and offers a continuous air barrier even for applications with complex geometries.
Hybrid STPE technology provides air infiltration and moisture protection while remaining easy to use even in low relative humidity and low temperature situations. Does not shrink and requires less wet film than comparable products to achieve dry film thickness. Apply it down to 25 degrees F. without additional additives.
