Acrylic copolymer hot melt formulation: HenkelRecent Research Landscape

Inconsistent bonding performance in hot melt applications leads to adhesive failure and production downtime. Precise control over the copolymer structure and UV-crosslinking density ensures thermal stability and substrate adhesion.

What technical problems is Henkel addressing in Acrylic copolymer hot melt formulation?

Insufficient substrate interfacial adhesion

(13)evidences

Standard radiation curing fails in opaque substrates or complex geometries where light cannot reach. Dual curing mechanisms ensure structural integrity in non-illuminated areas.

Thermal substrate degradation

(6)evidences

Standard acrylic hot melts suffer from poor internal crosslinking in thick layers due to limited light penetration. Integrating monomeric photoinitiators ensures uniform structural integrity throughout the adhesive bond.

Incompatible polymer phase separation

(3)evidences

Standard acrylic pressure sensitive adhesives suffer from shear failure and loss of structural integrity under thermal stress. Enhancing crosslinking density through UV-curable hybrid systems prevents adhesive flow and mechanical breakdown in demanding environments.
