Non-aromatic urea epoxy accelerators: SikaRecent Research Landscape

Delamination of electrical steel sheets during high-stress processing causes motor failure, which is mitigated by engineering the cross-linking density and wash resistance of the epoxy matrix. This ensures structural integrity in harsh manufacturing environments without requiring complex multi-part mixing.

What technical problems is Sika addressing in Non-aromatic urea epoxy accelerators?

Premature resin curing instability

(9)evidences

Inadequate bonding strength and structural integrity during high-stress processing or exposure to washing fluids. Improving resistance to mechanical and chemical displacement ensures reliable assembly of electrical components.

Inadequate low-temperature latency

(8)evidences

Latent epoxy systems suffer from a trade-off where lowering the activation temperature triggers unintended curing during storage. Resolving this instability allows for energy-efficient processing without compromising material shelf life.

Premature resin polymerization instability

(3)evidences

Latency failure in one-component systems leads to reduced shelf life and unintended polymerization. Preventing early reactivity ensures consistent material properties and handling characteristics prior to application.
