Hexion’s Esslingen Plant Increases Capability to Advance Wind Energy Development

Hexion's Wind-Dedicated Esslingen Plant is Now GL Approved for Fatigue Testing and Determination of Shear Properties of Adhesives, Neat Resins and Fiber Reinforced Plastics


Hexion’s 10,000 square meter, high-capacity specialty epoxy resin blending facility in Esslingen, Germany features a high-tech lab dedicated to Wind Energy applications. Mechanical and analytical testing operations there are Germanischer Lloyd (GL) approved, in the style of DIN EN ISO/IEC 17025: 2005, to cover testing and reporting for GL-certification of neat resins, GL-certification of bonding paste (except creep test), and common laminate test methods for our customer qualification program with glass and carbon fiber reinforced polymer (GFRP and CFRP).


To further R&D and improve customer support, our Esslingen plant has recently earned GL approval to perform three additional types of mechanical testing for adhesives, highlighted in the list below.
