Abstract:

A protective coating for a roof membrane of the type having plasticizers. The protective or barrier seal coating is applied the exposed surface of the polymeric roofing material, where it prevents and/or retards plasticizer migration to the surface of the membrane where they are subsequently removed. By preventing or retarding loss of plasticizers from the roof membrane, the concentration gradient of plasticizers throughout the membrane can be maintained and the life of the membrane can be extended. The protective or barrier seal coating may be further coated with conventional coatings such as elastomeric acrylics. Methods of applying the protective or barrier seal coating are disclosed.

Abstract:

A novel applicator for use in applying polyurethane and epoxy adhesives or cement to roofing components is disclosed where the applicator comprises a paired set of cartridges that are held together in spaced relation by at least one face plate, and where the cartridges include retainers for retaining a cap installed on the plunger end of each of the cartridges. The cap further comprises a plunger well for the receipt of the end of a plunger member of a dispenser and where the cap is displaceable within the inner bore of each of such cartridge under the urging of the dispenser resulting in the extrusion of a component of a two-part adhesive or cement into a mixing tube for mixing and dispensing through the tip of the mixing tube. The present invention preferentially includes two face plates for the display of product related information, one on each of the front and rear of the cartridge assembly.
