Water-based Epoxy Impregnating Varnish Selection Guide

广州飞思水性环氧绝缘浸渍漆全系列选型指南：FS7100 / FS7230 / FS7231 / FS7236 精准匹配绕组绝缘需求

从家电到工业电机，一站式解决绕组绝缘升级难题，助力企业高效完成溶剂型绝缘漆环保替代

I. Why Waterborne Epoxy Insulating Varnish Is the Inevitable Choice?

在环保法规趋严与电气设备能效升级的双重驱动下，传统溶剂型绝缘漆正加速退出市场。这类产品VOC排放高、易燃易爆、工艺控制复杂，已难以满足企业环评合规与安全生产的刚性要求。

相较于传统溶剂型方案，水性环氧绝缘浸渍漆具有三大不可替代的优势：

• Eco-friendly & Safe: Uses water as the dispersion medium to eliminate organic solvents, achieving low VOCs, no irritating odors, and non-flammable/non-explosive properties from the source. Significantly enhances workshop safety standards.

• 工艺宽容度高：支持沉浸、真空浸渍等多种施工方式，固化温度区间宽（80~130℃），适配不同产线条件

• 电气性能卓越：体积电阻率普遍达 1.0×10¹⁰ Ω·m 以上，电气强度 70~100 MV/m，确保设备在高电压、高湿环境下长期稳定运行

广州飞思合成材料有限公司作为水性绝缘材料领域的专业厂家，已为家电电机、工业电机、新能源设备领域提供成熟的规模化解决方案。

IV. Quick Product Matrix Selection Guide

Quickly locate the four products by application scenario:

• General Industrial Motors/Transformers → FS7100: High dielectric strength, strong adhesion, and excellent leveling

• Home Appliance Motors (Fans, Washers, AC Units) → FS7230: Excellent anti-flash rust, moisture resistance, and water durability

Fine-tune specific process parameters based on part size and on-site equipment conditions. Conduct trial runs before mass production.

5. Construction Recommendations and Craft Guidelines (Technical Tips)

1. 设备材质要求 储漆罐、循环管道、浸漆槽全部选用不锈钢材质。铁质容器生锈后铁离子进入漆液，极易导致乳液破乳，整桶漆料报废。

2. 温度控制——严守"双温"红线

• Workpiece Temperature: Cool the workpiece to room temperature before dipping. Never immerse hot workpieces! Excessive heat will raise the paint bath temperature beyond limits, causing skinning or emulsion break.

• Paint temperature: Keep the paint temperature below 30~40℃ during application. Excessively high temperatures can also cause emulsion destabilization.

1. Baking and Dehumidification: Keep the oven outlet clear to ensure rapid moisture removal during curing. Poor dehumidification will directly affect film dryness and substrate adhesion.

六、标准化施工工艺流程

所有飞思水性环氧绝缘浸渍漆均采用单组份体系，无需现场配比，开桶即用。标准四步工艺流程：

第一步：工件预处理 —— 确保线圈干燥、洁净、无油污杂质污染 第二步：浸渍 —— 普通沉浸或连续沉浸，时间 15 分钟，至液面无气泡冒出为止 第三步：滴漆沥干 —— 滴至工件无漆珠滴落，避免局部堆积造成漆膜不均 第四步：烘烤固化 —— 根据产品型号设定温度与时间（如 FS7100 推荐 120130℃ × 120~180min），实际参数依据工件尺寸调整

七、包装与储存规范

Packaging Specifications:

• 标准规格：20kg/桶、50kg/桶、200kg/桶、1000kg/桶（IBC吨桶）

• Supports on-demand customization to meet the needs of production lines of any scale.

Storage Conditions:

• Seal and store in a cool, dry place below 25°C
