电解着色膜多孔易变色，必须封护。室内摆件用微晶蜡（加热 60℃ 薄涂、冷却抛光）温润自然；户外或高湿环境用丙烯酸/聚氨酯清漆喷涂 2–3 道，隔绝水汽与硫化物。封护前确保膜干透、无手汗，否则会留印并加速膜下腐蚀。

Electro-colored films are porous and shift tone, so they must be sealed. Indoor ornaments take microcrystalline wax (thin coat at 60℃, buff when cool) for a natural sheen; outdoor or humid use gets 2–3 coats of acrylic/polyurethane lacquer to block moisture and sulfides. Ensure the film is bone-dry and fingerprint-free before sealing, or stains and under-film corrosion follow.
