31、the effects of the paint additives described before are overlapping - sometimes 1 additive can solve all issues, but very often combinations of the “specialists” are required. 有时一个助剂可解决所有问题, 但是这要求该助剂要有很综 合的性能. - siloxane-polyether co-polymers interact with other surfactants like paint additives (e.g

32、. pigment dispersants, or thickeners) resulting sometimes synergistic, sometimes negative effects. 聚醚改性硅氧烷聚合物和其他的涂料助剂(分散剂,稠变 助剂)配合使用时,有时会协同增效,有时会有负面作用. - the higher the molecular weight the higher the risk to get issues of re-coatability; in doubt go for the lower Mw. 高分子量可能存在重涂的隐患 在这种情况下,可选用分 子量较低的

33、品种. - COS with OH functional polyether most likely will cause issues of re-coatability (particularly -but not only- in PU coatings); they should be used for coatings where for sure no re-coating or repair coating is required only. 带有-OH的聚醚改性 聚合物易于产生重涂问题(尤其，但不仅局限于 PU涂料体系); 这些产品更适用于不要 求重涂或用于修补的涂料体系.
