    • A highly flexible mica winding tape is made by: (A) mixing epoxide resin with solvent, (B) adding from 0.01 to 5.0 parts per 100 parts epoxide resin of an organo-tin compound, and mixing to form a homogeneous admixture, (C) applying the admixture to a flexible sheet material comprising mica, so that the organo-tin compound contacts the mica, causing the organo-tin compound to act as a latent catalyst, and (D) removing solvent, to form a flexible sheet with substantially unreacted epoxide resin containing an amount of substantially unreacted organo-tin catalyst effective to advance the epoxide in the sheet material from the substantially unreacted state to a cured thermoset state upon heating over a resin-catalyst temperature of 120.degree.

    • 通过以下方法制备高度灵活的云母缠绕带:(A)将环氧树脂与溶剂混合,(B)每100份有机锡化合物环氧树脂加入0.01至5.0份,并混合形成均匀的混合物(C )将该混合物施加到包含云母的柔性片材上,使得有机锡化合物与云母接触,使有机锡化合物用作潜在催化剂,和(D)除去溶剂,形成基本上 含有一定量的基本上未反应的有机锡催化剂的未反应的环氧树脂有效地将片材中的环氧化物从基本上未反应的状态推进到在120℃的树脂催化剂温度下加热时固化的热固性状态。
