Anaerobically curable sealant and adhesive compositions comprising polymerizable acrylate esters or methacrylate esters and a redox system as accelerator are stabilized by the addition of sulfamide derivatives containing the group ##STR1## The stabilization may be further improved by using the sulfamides in combination with phenolic anti-oxidants, particularly sterically hindered phenols, without reducing the curing rate of the compositions.
无氧可固化密封剂和粘合剂组合物包括可聚合的丙烯酸酯或甲基丙烯酸酯和氧化还原体系作为加速剂,并通过添加含有基团##STR1##的磺酰胺衍生物来稳定。通过与酚类抗氧化剂特别是立体位阻饱和酚的结合使用磺酰胺衍生物可以进一步提高稳定性,而不降低组合物的固化速率。
