Acrylic hydrogel structural sealant: SikaRecent Research Landscape

Corrosion in reinforced concrete leads to structural failure and expensive manual replacement. These innovations utilize a reactive hydrogel delivery system to chemically arrest oxidation within hardened cementitious matrices.

What technical problems is Sika addressing in Acrylic hydrogel structural sealant?

Structural substrate corrosion and cracking

(2)evidences

Internal chemical deterioration and structural weakening of hardened concrete infrastructures. Preventing this failure mode extends the operational lifespan and safety of existing civil engineering assets.

Insufficient structural load capacity

(1)evidences

Weak interfacial adhesion and poor mechanical stability in wet environments lead to sealant failure. Improving bond strength ensures long-term durability in load-bearing applications.
