Beschreibung
Zusammenfassung:	The present invention relates to an anaerobically curable impregnation sealant composition and methods thereof containing a (meth)acrylic monofunctional monomer with a hydrophobic moiety, a (meth)acrylic monofunctional monomer with a hydroxyl group, a modified polyester urethane methacrylate resin having a weight average molecular weight of from about 8000 to about 18000 g/mol, and triallylisocyanurate, triallylcyanurate, or derivatives thereof, or a combination thereof. The present invention particularly relates to a sealant composition for impregnation to plastic and metal substrates that also provides resistance to thermal cycling. 本发明涉及一种可厌氧固化的浸渍密封剂组合物及其制备方法，所述组合物包含具有疏水部分的(甲基)丙烯酸类单官能单体，具有羟基的(甲基)丙烯酸类单官能单体，重均分子量为约8000-约18000g/mol的改性的聚酯氨基甲酸酯甲基丙烯酸酯树脂，以及三烯丙基异氰尿酸酯、三烯丙基氰尿酸酯、或它们的衍生物、或它们的组合。本发明特别涉及用于浸渍塑料和金属基材的密封剂组合物，该密封剂组合物也提供耐热循环性。
