KIT AND METHOD FOR SEALING ROOF PENETRATIONS
A kit and method 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.
