ASMACO PU 90 delivers excellent performance in sealing and weatherproofing tasks, thanks to its durable and flexible polyurethane formulation. Its ability to cure upon exposure to humidity makes it easy to use and efficient in a variety of climates. The sealant adheres well to a wide range of substrates, including concrete, wood, metal, and masonry, without the need for priming. In addition to its robust environmental resistance—protecting against moisture, UV rays, and temperature fluctuations—ASMACO PU 90 also provides an acoustically efficient barrier. This makes it particularly suitable for applications in sound-sensitive environments, such as residential buildings, studios, and commercial structures. Its sound-dampening capabilities help reduce noise transmission through joints, contributing to a quieter, more comfortable space.
