Description
Soudaseal 215LM Hybrid Polymer Façade Sealant
Soudaseal 215LM is a premium quality low modulus hybrid polymer sealant developed for professional façade, construction and industrial sealing applications. The formulation provides primerless adhesion to many common construction materials, including damp substrates, and is suitable for use on sensitive materials such as lead and natural stone. With extended tooling time compared to traditional silicones, Soudaseal 215LM allows easier finishing on larger joints while delivering durable, weather-resistant performance. When used as part of the Soudal Window System (SWS®), the sealant contributes to airtight window installation detailing.
