    • An insulated glass sealant includes an elastomeric matrix that is the reaction product of an acetoacetylated polymer and a cross-linking reagent having amino functionality, preferably a polyetheramine, polyamine, or polyamide. A method of sealing an insulated glass unit includes applying the insulated glass sealant to one or more glass sheets, disposing a spacer between the glass sheets, and contacting the glass sheets with the spacer to define an annular space between the glass sheets to produce the insulated glass unit. The sealants maintain the excellent attributes of traditional polyurethane sealants, such as low water swell, low moisture vapor transmission, good adhesion to the window frame, low migration of the insulating gas, and good workability, but without the use of polyisocyanates in the curing process. Methods for making the sealant and sealing insulated glass panels, such as glass windows, with these sealants, and the resulting articles, are also provided.
    • 绝缘玻璃密封剂包括弹性体基体,其是乙酰乙酰化聚合物和具有氨基官能团的交联剂,优选聚醚胺,聚胺或聚酰胺的反应产物。 绝缘玻璃单元的密封方法包括将绝缘玻璃密封剂施加到一个或多个玻璃板上,在玻璃板之间设置间隔件,并将玻璃板与间隔件接触以在玻璃板之间形成环形空间,以产生绝缘 玻璃单元。 密封剂保持传统聚氨酯密封胶的优良特性,如低水膨胀,低湿气传输,对窗框的良好粘附性,绝缘气体迁移率低,加工性好,但在固化过程中不使用多异氰酸酯 。 还提供了制造密封剂和密封隔热玻璃面板的方法,例如玻璃窗,这些密封剂,以及所得制品。
