Two-part polyurethane polymer network: SikaRecent Research Landscape

Sagging and inconsistent flow during application lead to structural bond failures and wasted material. Engineering the thixotropic response in two-part systems ensures precise bead placement and immediate green strength.

What technical problems is Sika addressing in Two-part polyurethane polymer network?

Inadequate structural bond strength

(12)evidences

Uncontrolled flow of liquid adhesives before curing leads to bond line failure and messy application. Maintaining structural integrity during the vertical application of laminates ensures precise bonding.

Poor initial substrate adhesion

(3)evidences

Inadequate adhesion to coated or painted surfaces leads to structural bond failure. Improving interfacial strength ensures mechanical integrity in multi-material assemblies.
