Surface Protection & Sealing
表面保护与封护

热着色膜极薄、耐磨差，封护决定保色寿命：①首饰/小件：极薄蜂蜡或专用"热色封护剂"（含苯并三氮唑缓蚀）②要求耐久：纳米陶瓷/二氧化硅镀膜（透明、耐汗）③忌厚漆（遮色、发闷）。封前确认膜冷透、表面洁净。日常避免硬物刮、强溶剂擦。烘烤着色的整体件可整件浸入或喷涂封护剂。
The heat film is thin and wears easily; sealing sets lifespan: ①jewelry/small: very thin beeswax or dedicated "heat-color sealer" (with benzotriazole inhibitor) ②durable needs: nano-ceramic/silica coating (clear, sweat-resistant) ③avoid thick lacquer (hides color, dulls). Before seal: film fully cool and clean. Avoid scratches and strong solvents in use. Oven-colored whole pieces can be dipped or spray-sealed entirely. ---
