Moisture-curable polyurethane hot melt: HenkelRecent Research Landscape
Slow green strength development in reactive hot melts delays downstream assembly and increases work-in-progress inventory. Precise crystalline polyol loading accelerates phase separation to provide immediate structural integrity.
What technical problems is Henkel addressing in Moisture-curable polyurethane hot melt?
Poor dimensional stability
(20)evidences
Standard polyurethane hot melts resist natural degradation and create long-term waste. Eliminating persistence through bio-based and enzymatic modifications enables end-of-life material breakdown.
Chemical degradation from oleic acid
(11)evidences
Slow crystallization rates in polyurethane hot melts lead to poor immediate bond strength before moisture curing occurs. Rapid structural integrity prevents substrate shifting during assembly.
Insufficient environmental degradation resistance
(8)evidences
Adhesive bond failure occurs when laminated films are subjected to high-temperature hot filling or retort processes. Preventing this degradation ensures packaging integrity under thermal and chemical stress.
