Metal-Crosslinkable Polymer Coating for Fast Heat-Triggered Curing

The patent applies preliminary action by incorporating a metal ion-releasing agent into the composition before use. This agent is designed to release metal ions only when heated to a specific temperature, which triggers the crosslinking reaction. The preliminary preparation of the composition allows it to remain stable during storage, while the pre-included metal ion-releasing mechanism ensures rapid curing once the temperature condition is met, thus resolving the contradiction between storage stability and curing time.

The patent replaces the optical mechanism (light-induced photopolymerization) with a thermal mechanism (heat-induced metal ion release and crosslinking). Instead of using photoinitiators that require light exposure, the composition uses a metal ion-releasing agent that responds to thermal energy. This substitution allows the material to cure at high speed regardless of light availability, making it adaptable to areas with limited light exposure while maintaining fast curing performance.

The patent changes the triggering parameter for curing from oxygen exclusion (chemical environment control) to temperature (thermal energy input). By using a metal ion-releasing agent that activates at a specific temperature, the curing process becomes independent of oxygen presence. This parameter change eliminates the need for complex oxygen blocking measures while maintaining fast curing speed, as the thermal activation mechanism proceeds regardless of atmospheric conditions.
