A two-component adhesive for structural engineered wood lamination

Hexion has introduced a new two-component adhesive system that reduces waste and cleanup costs, enhances durability and supports indoor air quality. This adhesive system, which includes the Ecobind 6500 resin and Wonderbond hardener M650Y, is optimal for applications like cross-laminated timbers for tall wood buildings and glue-laminated wood beams.

The two components are extruded separately and then mixed when the wood is pressed together. This unique feature provides the user with reduced costs for adhesive waste and cleanup off equipment. Ecobind 6500/Wonderbond M650Y also exceeds all strength, exterior exposure and high-temperature requirements of the North American Structural Wood standards (ANSI A 190.1, “Structural Glued Laminated Timber,” PRG 320, “Cross Laminated Timber,” and ASTM D 5456, “Structural Composite Lumber”).

“Hexion provides the enabling lamination technology for one of the most sustainable products on earth – engineered wood,” said Scott McIntyre, North American Business Director for Adhesives. “To ensure the lasting durability and performance of these sustainable engineered wood materials, we have had this new adhesive tested by multiple third party organizations.”

In addition to structural durability, the Ecobind 6500/ Wonderbond Hardener M650Y resin system has also achieved UL Greenguard Gold Certification. Greenguard Gold demonstrates that a product has met rigorous and comprehensive standards for low emissions of volatile organic compounds (VOCs) into indoor air and to account for sensitive individuals (such as children and the elderly). It is recognized, referenced or preferred by more than 400 federal purchasers, retailers, green building rating tools and building codes around the world, according to UL Environment, a division of UL (Underwriters Laboratories).

Mr. McIntyre added: “Hexion’s adhesive technology can meet or exceed all market performance and emissions criteria. Its highly valued chemistry provides thermal stability, is inherently flame resistant and results in a stable polymer matrix that is highly durable and safe under its intended conditions of use.”

Greenguard Certified products are certified to Greenguard standards for low chemical emissions into indoor air during product usage.

Ultra-low emitting EcoBind resins are formulated to meet or exceed all global emissions standards, including those from the US Environmental Protection Agency, California Air Resources Board (CARB), and Japanese standards as well as the specifications recommended by the Green Building Initiative and U.S. Green Building Council. Reflecting Hexion’s ongoing commitment to innovation, the company recently announced the expansion of its technology center at its forest products complex in Edmonton, Alberta. The expanded research and development facility will develop next generation resin chemistry that will complement existing EcoBind technology.
