CG-108D is a reflection-reducing coating material developed by Chenguang New Material for high-temperature, high humidity, high salt fog and other regions. Based on sol-gel technology to prepare silica, with isopropanol/ethanol as dispersing medium, it prevents sodium and calcium ions in the glass substrate from precipitation under harsh conditions by customising the ion-blocking underlayer (by adding metal ions), and achieves excellent weathering performance. Design Idea: Double-layer coating design, fully enclosed surface 1. surface layer internal independent, non-connected, hole structure 2. Bottom layer customised ion barrier
