Isomat 310ml FLEX PU-40 Elastomeric adhesive and sealant white

PRODUCT DESCRIPTION

 Isomat FLEX PU-40 White is a high-performance, one-component polyurethane elastomeric adhesive and sealant designed for heavy-duty sealing and bonding applications in construction and industrial projects. Formulated with advanced polyurethane polymers, it cures upon contact with atmospheric moisture to form a permanently elastic, highly durable seal. It features exceptional adhesion to a wide variety of building materials including concrete, masonry, aluminum, steel, wood, and glass, making it ideal for expansion joints, structural sealing, perimeter frames, and flexible bonding subject to vibration, movement, and severe weather.
