Sopraseal® LM 204 VP, a one-component, 98% solids content, low-odor, vapor-permeable, liquid-applied polyether air barrier product, is now available from Soprema®. This new, hybrid STPE (silyl terminated polyether) technology provides excellent air infiltration and moisture protection while also offering ease of use in low- and high-temperature applications, superior elastomeric performance and tie-in compatibility.
A fully adhered, monolithic membrane option, Sopraseal LM 204 VP offers a continuous air barrier that works well even in applications where conformity to complex geometries is a must. It is ultra-low-VOC and moisture curable in low relative humidity and low-temperature applications, while exhibiting excellent freeze-thaw characteristics. It does not shrink and requires less wet film to achieve dry film thickness.
Sopraseal LM 204 VP can be applied in temperatures down to 25°F without the use of additional additives. It is also available in an accessory product, Sopraseal® Liquid Flashing—a high quality, 100 percent solid, low-odor, STPE membrane designed to provide air and water protection to critical rough openings while sealing joints and creating a seamless transition to air barrier membranes.
