    • In one aspect, this invention is a polyurethane sealant composition comprising (1) a urethane prepolymer having an isocyanate functionality of at least about 2.0 and a weight average molecular weight of at least about 2,000; and (2) a catalytic amount of (a) a substantially active hydrogen free glycol acid salt of a tertiary amine and an organo metallic compound, (b) a mixture of a substantially active hydrogen free glycol acid salt of a tertiary amine and an organo metallic compound and a second organometallic compound, or (c) a mixture of an organometallic compound with dimorpholinodialkyl ether or an dialkylmorpholinodialkyl ether. In another embodiment, the polyurethane sealant composition further comprises (A) a silane, or (B) an adduct of an isocyanate reactive silane and a polyisocyanate, (C) the reaction product of an isocyanate reactive silane or an adduct of an isocyanate reactive silane and a polyisocyanate with a polyisocyanate and an active hydrogen containing compound or a polyurethane prepolymer which has free isocyanate moieties; which reaction product has an average of at least one silane group and at least one isocyanate group per molecule. In another embodiment the invention is a method for bonding glass to a substrate which comprises contacting a sealant according to the invention with glass and another substrate with the sealant disposed between the glass and substrate and thereafter allowing the sealant to cure so as to bind the glass to the substrate. The sealant composition of the invention is useful in bonding glass substrates to metal plastic, fiberglass or composite substrates, which may or may not be painted. It has been discovered to give unexpectedly high lap shear strength when no primer compositions have previously been applied to the painted plastic, metal, fiberglass or composite substrate.
    • 一方面,本发明是一种聚氨酯密封剂组合物,其包含(1)具有至少约2.0的异氰酸酯官能度和至少约2,000的重均分子量的氨基甲酸酯预聚物; 和(2)催化量的(a)叔胺和有机金属化合物的基本上活性的无氢二醇酸盐,(b)叔胺的基本上活性的无氢二醇酸盐和有机金属的混合物 金属化合物和第二有机金属化合物,或(c)有机金属化合物与二吗啉代二烷基醚或二烷基吗啉代二烷基醚的混合物。 在另一个实施方案中,聚氨酯密封剂组合物还包含(A)硅烷或(B)异氰酸酯反应性硅烷和多异氰酸酯的加合物,(C)异氰酸酯反应性硅烷或异氰酸酯反应性硅烷的加合物的反应产物 和具有多异氰酸酯和含活性氢化合物或具有游离异氰酸酯部分的聚氨酯预聚物的多异氰酸酯; 该反应产物每分子具有至少一个硅烷基团和至少一个异氰酸酯基团的平均值。 在另一个实施方案中,本发明是将玻璃粘合到基底上的方法,其包括使根据本发明的密封剂与玻璃和另一基底接触,所述密封剂设置在玻璃和基底之间,然后使密封剂固化以便将玻璃粘合 到基底。 本发明的密封剂组合物可用于将玻璃基材粘合到金属塑料,玻璃纤维或复合基材上,其可以涂漆或可以不被涂漆。 已经发现当没有底漆组合物已经施加到涂漆的塑料,金属,玻璃纤维或复合基材上时,出现意想不到的高搭接剪切强度。

    • A process for applying an adhesion primer to a window. The process includes the steps of directing light (11) onto the window (10) to illuminate a portion (13) of the window and then applying an adhesion primer along the illuminated portion of the window. If the adhesion primer contains a component that evaporates, then the process can further include the step of forming an infrared image (19) of the window as the component evaporates to indicate the area of application (20) of the adhesion primer. If the adhesion primer contains a component that fluoresces when illuminated by ultraviolet light, then the process can further include the step of illuminating the window with ultraviolet light (22) to indicate the area of application (23) of the adhesion primer.
    • 将粘合剂引入窗户的方法。 该方法包括以下步骤:将光(11)引导到窗口(10)上以照亮窗户的一部分(13),然后沿窗户的照明部分施加粘合底漆。 如果粘合底漆含有蒸发的组分,则该方法还可以包括当组分蒸发以形成粘合底漆的涂布面积(20)时,形成窗口的红外图像(19)的步骤。 如果粘合底漆含有当被紫外线照射时发荧光的成分,则该方法还可以包括用紫外线(22)照亮窗口以指示粘合底漆的施用面积(23)的步骤。
