80 Years of Enabling Technology

Hexion continues to enable the expanded use of wood in building and construction and leads the charge as we’ve done for more than 80 years.

Our versatile EcoBindTM adhesives for structural engineered wood products recently completed all independent laboratory testing required by the American National Standards Institute (ANSI) and is certified for high volume manufacture of glue laminated beams (glulam) and cross-laminated timber (CLT).

Hexion received full qualification of its EcoBind 6500 resin with Wonderbond™ M650Y-M700Y hardener.  This ultra-low emitting EcoBind resin successfully passed both the ANSI PRG 320-18 standard, which covers the manufacturing, qualification, and adhesive requirements for CLT, and the ANSI 405-18 standard, which provides adhesive evaluation requirements for use in structural glulam. The EcoBind 6500 system complies with the International Code Council’s (ICC) Tall Wood Code changes adopted for the 2021 version of the International Building Code.

The complete list of test details:

  • ASTM D2559-12, “Standard Specification for Adhesives for Structural Laminated Wood Products for Use Under Exterior (Wet Use) Exposure Conditions”, (includes D3535) utilizing both Ambient and Radio Frequency cure methodologies Douglas Fir Substrate Southern Yellow Pine Substrate
  • ASTM D7247-16, “Standard Test Method for Evaluating the Shear Strength of Adhesives Bonds in Laminated Wood Products at Elevated Temperatures” 60 minutes duration at 450°F bond line temperature, 70% wood degradation
  • ASTM D1151, “Standard Practice for Effect of Moisture and Temperature on Adhesive Bonds”Exposure Number 3, “-34°C, presoaked”
  • ASTM D1183, “Standard Practices for Resistance of Adhesives to Cyclic Laboratory Aging Conditions”Test Condition D, “Exterior, marine”
  • CSA 0112.9  “Evaluation of Adhesives for Structural Wood Products (Exterior Exposure)”
  • CSA O177 – Section A.2, “Small Scale Flame Test” Glulam orientation per ANSI 405-18 and CLT orientation per PRG 320-18PRG 321-18 Annex B, “Practice for Evaluating Elevated Temperature Performance of Adhesives used in Cross-Laminated Timber:”

Hexion has been enabling the forest products industry for more than 80 years with its resins and adhesives. Not only do manufacturers see improved benefits in production, but the forest products industry continues to see gains in sustainability – something we should all be proud of.

For example:

By the numbers…

  • An average U.S. single family home stores approximately 9.3 metric tons of carbon which is equivalent to 34 tons of CO21
  • Constructing a wall using kiln-dried wood studs, oriented strand board (OSB) sheathing, and vinyl siding instead of concrete with an exterior stucco coating results in 15 pounds of avoided CO2 emissions for every square foot of wall area. 2
  • The carbon balance of a timber-frame building is estimated to be 114 – 151kg CO2 per m2 while a concrete-frame is 292 kg CO2 per m2 (Forestry for a low-carbon future, UN 2016)
  • Using engineered wood I-joists with an OSB sub-floor rather than steel joists and OSB sub-flooring results in 22 pounds of avoided CO2 emissions for every square foot of floor area. 2

A lot can happen in a minute…

  • Every minute, on average, new tree growth adds more than 50,000 cubic feet of wood to U.S. forests. In fact, U.S. forests sequester about 800 million metric tons of CO2 per year.1
  • In that same average minute, more than 24,000 cubic feet of wood are removed from US forests to build homes, make furniture, and create other products. Each year, 10-45 million tons of CO2 are stored in new wood products.3

Sustainability of Hexion Resins in Engineered Wood Products

Life cycle assessments (LCAs) show wood buildings require less energy2 from resource extraction through manufacturing, distribution, use and end-of-life disposal and are responsible for far less greenhouse gas emissions than other building materials such as steel or concrete.
