A curable composition comprises an insulating resin and a halogen-free flame retardant. The halogen-free flame retardant has a particulate form, and whose primary particles have an average major axis from 0.01 to 5 &mgr;m, an aspect ratio of 5 or less, and the proportion of a major axis of more than 10 &mgr;m being at most 10% by number. A varnish comprises an insulating resin, a curing agent, a flame retardant and an organic solvent. The flame retardant is a flame retardant in particulate form surface-treated with a coupling agent, and the flame retardant particles present in the varnish have a secondary particle diameter of 30 &mgr;m or less.
一种可固化组合物由绝缘树脂和无卤阻燃剂组成。无卤阻燃剂呈颗粒状,其主要颗粒的平均主轴为 0.01 至 5 微米,长宽比为 5 或以下,主轴大于 10 微米的颗粒所占比例最多为 10%。清漆由绝缘树脂、固化剂、阻燃剂和有机溶剂组成。阻燃剂是一种经偶联剂表面处理的颗粒状阻燃剂,清漆中的阻燃剂颗粒的二级颗粒直径不超过 30 微米。
