Can dimethyl silicone oil be used as a sealing coating that requires curing to form a film?
As a type of non-curable silicone oil, conventional linear dimethyl silicone oil (i.e., ordinary polydimethylsiloxane, PDMS) has inherently different core properties from curable systems. Although it cannot form a cured film with a three-dimensional network structure through chemical reactions, its unique physicochemical properties still make it irreplaceable in specific scenarios. The following analysis is carried out from three dimensions: technical principles, performance boundaries, and typical applications.
