For roofing contractors installing single-ply roofing systems who prefer a low-odor and less hazardous adhesive option, Del-Val 203 Water-Based Bonding Adhesive from United Asphalt provides a high-performance alternative to solvent-based products. This adhesive is specifically designed to bond single-ply roofing membranes, including popular types like TPO, EPDM, and PVC, to a wide range of compatible roofing surfaces.
A key advantage of Del-Val 203 is its water-based formulation, which allows it to dry quickly without emitting the strong odors and potential hazards typically associated with solvent-based adhesives. Once established, the bonded application provides a dependably strong performance, ensuring the secure attachment of the single-ply membrane to the roof deck.
Uses include attaching TPO, EPDM, and PVC single-ply roofing membranes to virtually all roofing surfaces. Proper preparation is essential; all surfaces must be clean and free of any oil, grease, dirt, and all other foreign matter that would interfere with good adhesion. Apply Del-Val 203 to a clean, dry surface using a roller or spray equipment. For best curing results, the temperature during and after application should be a minimum of 40°F with humidity less than 90%. Higher application rates will extend the adhesive’s cure time.
Coverage varies depending on the application method and substrate. For standard applications to the underside of the membrane and the roof surface, apply at a rate of 1 gallon per 100 – 120 sq. ft. (to each surface). For wet lay-in applications or if installing a fleece backed membrane, apply to the roof surface only at a minimum rate of 2 gallons per 100 sq. ft. Cleanup of tools can be done with Del-Val Orange Cleaner & Degreaser or mineral spirits, taking necessary precautions when handling combustible liquids. Del-Val 203 has a shelf life of twelve months from the date of manufacture.
