Residual monomeric diisocyanate concentration: SikaRecent Research Landscape

Slow green strength development in hot melts leads to assembly slippage and production bottlenecks. Precise control of the isocyanate-to-polyol ratio and moisture-triggered crosslinking density ensures rapid structural integrity and thermal stability.

What technical problems is Sika addressing in Residual monomeric diisocyanate concentration?

Residual monomer toxicity

(28)evidences

Excess unreacted diisocyanate monomers pose significant health risks and compromise the structural stability of the final adhesive. Reducing these levels mitigates chemical exposure hazards and prevents premature degradation of the moisture-curable matrix.

Inadequate substrate adhesion versatility

(3)evidences

Residual isocyanates in adhesives pose significant respiratory and dermal toxicity risks during application. Reducing these concentrations mitigates health hazards and ensures regulatory compliance in industrial environments.
