  溶剂型和无溶剂涂料在其涂料生产,装料和应用期间防止泡沫和起泡形成所用的硅类消泡剂,对于喷涂﹑刷涂和辊涂有效。BYK-41用于一般工业涂料、地坪涂料和木制底材用涂料中,在各种基料体系中,其清漆性好,无缩孔和再涂性问题。较适用的基料是无油聚酯类,型,聚氨酯类,环氧酯类,硝化棉和酸固化。

  消泡剂有油型、溶液型、乳液型、固体粉末型和复合型等. 它们应具有以下特性:
  1. 消泡力强,用量小;

  有机硅消泡剂的类型
  1. 水中乳液消泡剂
宝乐彩票平台  以聚二甲基硅氧烷(二甲基硅油)为主体,在表面活性剂(乳化剂)的作用下,将白炭黑复合物制备成不同浓度的o / w型水乳液消泡,或者制备成高浓度硅膏,通过涂抹法或临时稀释后使用。

  二甲基硅油结构式
  2. 油系统消泡剂
  硅油被溶剂携带并分散到起始液体中。 溶剂扩散、硅油或微滴起消泡作用(通常是高粘度和低粘度硅油混合)或制成硅油/矿物油分散体。 石油工业需要大量有机硅表面活性剂作为破乳剂。

  3. 固体粉末消泡剂
  包含2 - 5质量%的有机硅消泡组分和98 - 50质量%的粉末状固体载体。

  4. XIAOPAOGAN

  5. 自乳化自分散消泡剂
宝乐彩票平台  与聚硅氧烷和聚醚共聚的硅氧烷表面活性剂可以通过在聚硅氧烷分子链中引入亲水基团(聚醚改性硅油)来显著改善硅氧烷在水中的分散性,或者可以形成自乳化形式,成为一种特殊的消泡剂,在浊点以上消泡,并且适合于消泡,例如高温高压喷射染色。
