Use Unobond for: Structural bonding of diverse materials, including wood, metals, plastics, and masonry. Ideal for water-resistant and marine applications.
Unobond is a versatile, one-component polyurethane adhesive that delivers a strong, durable bond across various substrates. Its moisture-curing formula ensures a fast set and excellent water resistance, meeting D4 classification standards. This adhesive is perfect for demanding applications, including exterior woodwork and marine environments, where a reliable and long-lasting bond is essential. Unobond's slight expansion fills gaps and irregularities, enhancing its bonding capabilities.
