Abstract: 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.

Abstract: Durable stretch fabrics are made and processed from one or more crosslinked, heat-resistant olefin elastic fibers, e.g., a substantially linear, homogeneously branched ethylene polymer. The fabrics can be made by any process, e.g., weaving, knitting, etc., and from any combination of crosslinked, heat-resistant olefin elastic and inelastic (“hard”) fibers, e.g., cotton and wool. These fabrics exhibit excellent chemical, e.g., chlorine, resistance and durability, e.g., they retain their shape and feel (“hand”) over repeated exposure to processing conditions, e.g., stone-washing, dye-stripping, PET-dyeing and the like, and service conditions, e.g., washing, drying, etc.

Abstract: Polyurethane foams are made and attached to a substrate having an open cavity, but reacting a polyisocyanate component and a polyol component in the presence of a blowing agent. The polyisocyanate component includes at least one isocyanate-terminated, oxazolidone-containing intermediate. This process allows for very fast curing, good quality, adherent foams to be produced on, for example, vehicle parts and assemblies, for acoustical or vibration dampening and for structural reinforcement.
