    Abstract: 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.

    Abstract: A novel composition for use as a print head face plate coating. In particular, the coating comprises siloxyfluorocarbon (SFC), which is composed of networked precursors containing reactive siloxane groups attached to fluorocarbon chains. The present SFC coatings can be used to produce a surface whereby solid ink and ultraviolet (UV) curable inks do not adhere when applied at elevated temperatures and over an extended period of time. The advantages of the present coating are fewer print head related defects, and longer front face life.
