    • A moisture curable acrylic formulation is provided inclusive of a majority by weight polyacrylic prepolymer. The prepolymer has an average molecular weight of between 3,000 and 6,000 grams per mole and between 2 and 4 moisture curable functional moieties of isocyanate or silane per prepolymer. A thermoplastic adhesive resin is also included within the formulation. When the prepolymer functional moieties are all silane, the thermoplastic adhesive resin is ethylene vinyl acetate resin. A silane molecule is provided within the formulation as an adhesion promoter and also affords a degree of storage stability through sacrificial reaction with water during storage. The resultant formulation achieves a shear strength of at least 10 pounds per square inch when applied to a thickness of 0.75 millimeters between a glass substrate and a vinyl article 15 minutes after application at 120° Celsius in ambient atmospheric air. The formulation is well suited for the formation of a window assembly when applied intermediate between a substrate and a window article.
    • 提供了一种包含大多数按重量计的聚丙烯酸预聚物的防湿固化丙烯酸制剂。 预聚物的平均分子量为3,000至6,000克/摩尔,在每个预聚物中具有2至4个异氰酸酯或硅烷的湿气固化功能部分。 制剂中还包括热塑性粘合剂树脂。 当预聚物官能部分都是硅烷时,热塑性粘合剂树脂是乙烯 - 乙酸乙烯酯树脂。 在制剂中提供硅烷分子作为粘合促进剂,并且还通过在储存期间与水的牺牲反应提供一定程度的储存稳定性。 当在环境大气中在120℃下施用15分钟后,所得配方实现至少10磅/平方英寸的剪切强度,当施加到玻璃基板和乙烯基制品之间的0.75毫米厚度时。 该配方非常适用于当应用在基材和窗户制品之间时的窗组件的形成。

    • A polyacrylic polymer is provided that is formed by moisture cure of multiple acrylic prepolymer segments. The prepolymer segments each have an average molecular weight of between 5000 and 400,000 grams per mole. Each of the prepolymers is a homopolymer or copolymer of a monomer from among methyl methacrylate, C1-C16 alkyl acrylate, and C1-C16 alkyl methyl methacrylate as the predominant monomeric group. The prepolymers are interconnected through moisture cure induced urea, urethane, or combinations thereof. The polymer is readily cured upon exposure to atmospheric moisture absent inclusion or evolution of a volatile organic compound. The polymer is likewise formed HAP free. Through control of prepolymer properties a variety of thermoset polymer properties are obtained. A prepolymer is formed including a minority amount of functionalized acrylic monomer that is isocyanate or converted to isocyanate through subsequent reaction. Functionalized acrylic monomers operative herein include a hydroxyl, a primary amine, a secondary amine, a sulfonic acid, or an epoxy. Upon application from storage in an anhydrous state, the prepolymer cures upon exposure to atmospheric moisture.
    • 提供通过多个丙烯酸预聚物段的湿固化形成的聚丙烯酸聚合物。 预聚物段各自的平均分子量为5000至400,000克/摩尔。 每种预聚物是甲基丙烯酸甲酯,丙烯酸C1-C16烷基酯和甲基丙烯酸C1-C16烷基甲基丙烯酸酯作为主要单体基团的单体的均聚物或共聚物。 预聚物通过湿固化诱导的尿素,氨基甲酸酯或其组合相互连接。 暴露于大气中的水分时,聚合物很容易固化,不含挥发性有机化合物的夹杂物或析出物。 聚合物同样形成不含HAP。 通过控制预聚物的性能,可获得各种热固性聚合物的性能。 形成预聚物,其包含少量的官能化丙烯酸单体,其是异氰酸酯或通过随后的反应转化成异氰酸酯。 在此可操作的官能化丙烯酸单体包括羟基,伯胺,仲胺,磺酸或环氧基。 当以无水状态储存时,预聚物在暴露于大气湿度下固化。
