Alkali dispersible hot melt adhesives: HenkelRecent Research Landscape

Standard adhesives contaminate recycling streams by forming non-soluble residues, which is mitigated through pH-triggered polymer backbone dissociation. This allows for clean substrate separation and higher purity recovered material.

What technical problems is Henkel addressing in Alkali dispersible hot melt adhesives?

Inadequate post-use adhesive solubility

(23)evidences

Standard hot melt adhesives fail to separate from substrates during recycling or laundering processes. Eliminating persistent adhesive residues prevents equipment fouling and enables high-purity material recovery.

Adhesive bond failure under stress

(9)evidences

Standard pressure sensitive adhesives contaminate recycling streams and prevent substrate recovery. Eliminating persistent residues enables material circularity and reduces processing waste.
