Product Details
Product Overview
Primarily used in bisphenol A-type epoxy resin/anhydride systems.
Product Function
1. Above the critical temperature, the system reaction is accelerated, shortening the gelation time; below the critical temperature, the storage life of the system is extended, and the reaction is inhibited.
2. Maintain the cured system’s excellent mechanical and electrical properties.
Application Fields
1. A latent accelerator for anhydride-cured bisphenol A epoxy resins, which can be widely used as a curing accelerator for epoxy mica tapes (such as 5438, 5440-1, and 5440-2) employed in the main insulation materials of large electric motors.
2. A solvent-free impregnation varnish accelerator for acid-cured epoxy systems, which enhances varnish stability and shelf life and improves its electrical performance.
3. Used in epoxy potting systems (insulating components for high-voltage switches in power transmission and transformation equipment, dry-type transformers, and instrument transformers).
4. A curing accelerator for epoxy/phenolic resin systems, epoxy/dihydroxyamine systems, phenolic resin systems, and bismaleimide polyimide resin systems.
5. Latent accelerators for BT resins and cyanate ester/epoxy resins.
