    • A method and kit for forming a seal around a roof penetration is disclosed. The method comprises dispensing a one-part moisture curable sealant into pitch pan formed around a roof penetration. The one-part moisture curable sealant contains a polymer having non-terminal silane groups. The incorporation of non-terminal silane groups can provide for a greater number of crosslinking points than terminal silane groups. The non-terminal silane groups can be placed at specific points along the polymer backbone and the number of crosslinking points, or concentration of crosslinking units, can be controlled. Generally, as the crosslinking points can be provided along the polymer chain, the number of crosslinking points is increased, especially as compared to polymers only having terminal silane groups. Increasing the number of crosslinking points can result in improved elasticity and cure-through as compared with silyl-terminated polymers, in addition to other advantages.
    • 公开了一种用于在屋顶穿透周围形成密封的方法和套件。 该方法包括将一部分可湿气固化的密封剂分配到围绕屋顶穿透形成的沥青盆中。 一部分可湿固化的密封剂含有具有非末端硅烷基团的聚合物。 非末端硅烷基团的引入可提供比末端硅烷基团更多数量的交联点。 可以将非末端硅烷基团放置在沿着聚合物主链的特定点处,并且可以控制交联点的数量或交联单元的浓度。 通常,由于沿着聚合物链可以提供交联点,所以交联点的数量增加,特别是与仅具有末端硅烷基团的聚合物相比。 与甲硅烷基封端的聚合物相比,增加交联点的数量可以导致改善的弹性和固化,以及其它优点。
