Röhm DEGADUR® AD 942 MMA and n-BUMA based polymer
Categories: Other Engineering Material; Additive/Filler for Polymer; Polymer

Material Notes: DEGALAN® AD series are MMA and n-BUMA based polymers for one-component reactive hot melt (moisture curable). Those polymers are designed to modify reactive hot melt properties for woodworking applications, such as multi-layer composites and honeycomb structures for furniture and doors as well as for bookbinding applications. The product range presents a comprehensive set of properties variation regarding viscosity, molecular weight, glass transition temperature and acid number. DEGALAN® AD series offers:
  • Increased hot tack
  • Longer open time
  • Lower viscosity
  • Higher initial mechanical resistance
  • Acid or hydroxyl functionality
