Binders for the Engineered Lumber Industry
“Last a life time”
High-performance binders based on polymeric MDI (pMDI) are the first choice for engineered lumber. Top-quality polyurethane binders were developed in Bayer’s laboratories in the early 1970s. The experience gained over past three decades is now reflected in today’s generation of Mondur® isocyanates, enabling high-productivity in the manufacture of modern engineered lumber, such as chipboard, OSB, MDF and molded particle boards. The crosslinked polyureas for during hot-pressing yield moisture-resistant sheets and moldings. Mondur® binders are not soluble in water and do not require catalysis, which eliminates pot-life limitations inherent with other binder types. This greatly simplifies the manufacture of engineered wood and increases productivity. Excellent functional and further processing properties mean the products can be used both in outdoor construction and indoors as emission-free wall, ceiling and floor boards. They are also much sought-after in the furniture industry. Mondur® binders are also increasingly used with plant-based raw materials that are difficult to bond, such as straw, bagasse and other fibers.
