GE-branded Enduris silicone roof coatings are manufactured by Momentive Performance Materials Inc., the global licensee of GE silicone sealants and coatings since 2006, with coatings produced in Waterford, NY and corporate headquarters in Niskayuna, NY. The Enduris line is a 100% silicone, high-solids, solvent-free restoration platform (Enduris 3500, 3500 E+, 3525, plus liquid flashing, bleed blockers and reinforcing fabrics) sold through a national distributor network rather than direct. Systems installed by contractors in Momentive's Authorized Applicator Program qualify for labor-and-material warranties up to 20 years. The 20-year single-ply restoration spec requires 2.5 gal/100 sq ft applied to a minimum 36-mil dry film.
