三防漆是哪三防？

三防涂料防潮、防盐雾、防霉。

防漆是一种特殊配方的涂料，用于保护电路板及相关设备免受环境侵蚀，从而延长其使用寿命，保证使用的安全性和可靠性。

在真实条件下，如化学环境(燃料、冷却剂等。)、振动、高粉尘、盐雾、潮湿和高温等。，电路板可能会出现腐蚀、软化、变形、发霉等问题，导致电路板出现电路故障。

三防涂料涂覆在电路板表面，形成一层厚度约为25-50微米的轻质柔性薄膜。它可以在上述恶劣条件下保护电路免受损坏。

三防漆的名称很多，有三防胶、防潮胶、绝缘胶、防潮油、三防油、防潮剂、保形涂料、涂层、保护漆、覆盖胶、涂层胶、防水胶、保形涂料、通用涂料等。英文名是conformal coating。

透明三防漆可以改善印刷电路板的外观，亮度很到位，就像穿了一层不透气但很漂亮的衣服。
