Crosslinking Agent: Storage Temperature 5-25°C

Component Specifications

Definition

A chemical additive used in electrical insulation varnish compounds to initiate and control crosslinking reactions between polymer chains, forming a durable, thermally stable, and electrically insulating network that enhances mechanical strength, thermal resistance, and dielectric properties of cured varnish coatings.

Working Principle

Works through chemical reactions (typically thermal, UV, or moisture-cured) that create covalent bonds between polymer chains, transforming linear or branched polymers into a three-dimensional network structure that provides dimensional stability and improved performance characteristics.

Materials

Typically organic peroxides (e.g., dicumyl peroxide), amines, isocyanates, silanes, or epoxy hardeners; may include catalysts, inhibitors, or accelerators; supplied as liquids, pastes, or powders with controlled reactivity profiles.
