Product Highlights

核心优势

Redefining the quality standards of automotive repair coating

卓越防腐蚀性能

环氧聚酰胺固化体系形成致密涂层，有效阻隔水、氧和腐蚀性离子渗透。耐盐雾测试500h+无起泡锈蚀，为金属基材提供可靠的长期防腐保护。

多基材通用

与冷轧钢板、镀锌板、铝合金、不锈钢等多种汽车常用基材均具有优异的附着力。无需针对不同基材频繁更换底漆产品，简化采购和库存管理。

快干高效

60°C烘烤30分钟即可实干打磨，常温25°C条件下2-4小时可打磨。活化期长达4小时，大板喷涂无需频繁调配，施工效率提升显著。

优异的填充封闭性

高固含配方（55%+），对打磨痕、细微缺陷有良好的填充遮盖能力。可有效封闭原子灰层的孔隙，防止面漆被吸收导致失光。

兼容性强

与原子灰、中涂底漆、面漆、清漆等后续涂层均具有优异的层间附着力。适用于PPG、BASF、Axalta等主流品牌配套体系。

低VOC环保配方

VOC content<420g/L，符合GB 24409-2020标准。铬酸盐含量符合最新环保法规要求，满足汽车主机厂对环保材料的使用规范。
