Silane terminated polyurethane crosslinking: HenkelRecent Research Landscape

Substrate delamination and sealant failure lead to catastrophic structural degradation in harsh environments. These compositions engineer the interfacial bond strength through specific silane-based chemical coupling to ensure long-term mechanical integrity.

What technical problems is Henkel addressing in Silane terminated polyurethane crosslinking?

Insufficient interfacial bond strength

(25)evidences

Substrate detachment and poor surface wetting lead to structural failure in bonded assemblies. Improving interfacial integrity ensures long-term mechanical stability and environmental resistance.

Slow ambient moisture curing

(9)evidences

Inherent immiscibility between polar polyether/polyurethane segments and non-polar siloxane chains leads to poor mechanical integrity. Overcoming this thermodynamic instability ensures structural homogeneity and prevents material delamination.
