Global Neutral Silicone Sealants Market – View in Detailed Research Report

The market is defined by polydimethylsiloxane blended with crosslinking agents, fillers, plasticizers, coupling agents, and catalysts. When exposed to ambient moisture, the formulation cures into an elastic silicone rubber that releases only alcohol, ensuring a virtually odorless application. This chemistry translates into superior bond strength on PVC‑U, most plastics, glass, aluminium, stone, masonry, and polycarbonate.
