Enzymatically modified starch tackifier: HenkelRecent Research Landscape

Standard bio-based adhesives suffer from dimensional instability and poor tack, which leads to bond failure under mechanical stress. This lever utilizes specific enzymatic starch modification to control the cross-linking density and rheology of compostable polyurethane systems.

What technical problems is Henkel addressing in Enzymatically modified starch tackifier?

Insufficient substrate adhesion strength

(14)evidences

Standard adhesives fail to maintain structural integrity under mechanical stress during transport. Strengthening these bonds prevents package failure and product loss.

Adhesive dimensional instability

(14)evidences

Conventional pressure-sensitive and hot melt adhesives rely on petroleum-based polymers that resist environmental degradation. Replacing these with enzymatically modified starch addresses the lack of compostability in industrial bonding agents.

Low temperature bond failure

(8)evidences

Residual unreacted isocyanate monomers pose significant respiratory and skin toxicity risks during adhesive application. Eliminating these emissions ensures regulatory compliance and worker safety without compromising adhesive performance.
