For roofing contractors demanding the highest level of performance, flexibility, and weatherability from a coating, Del-Val 320 Silicone Roof Coating from United Asphalt is an exceptional solution. This one-part, 100% silicone elastomeric coating is specifically designed for the rigorous demands of roofing applications. Once cured, it forms a durable, seamless, flexible, and waterproof membrane that not only accommodates normal expansion and contraction but also resists lateral movement and shear, providing exceptional stability for the roof system.
Del-Val 320 provides greater UV protection than similar coatings, safeguarding the roof from degradation caused by prolonged sun exposure. It also offers increased resistance to moisture penetration, ensuring a reliable waterproof barrier. With exceptional weatherability properties, Del-Val 320 is proven to provide excellent long term protection. It boasts excellent adhesion to all substrates it’s designed for, offering a strong, reliable bond. Its proven excellent solar reflectivity contributes to reducing roof temperatures, making it a Cool Roof Rated product that can lead to significant energy savings. It also meets or exceeds the requirements of ASTM D-2824 Type III.
This silicone coating was specifically developed as a protective coating for a wide range of challenging substrates, including single-ply membranes (such as EPDM, TPO, and Hypalon), granulated modified bitumen, metal, and sprayed-in-place polyurethane foam (SPF) roofing. It is also effectively used as a top coat over moisture cure polyurethane in membrane restorations, providing a high-performance finishing layer.
Proper preparation is crucial for successful application; the surface must be clean and free of dirt, dust, oil or grease, and any other foreign matter that would interfere with good adhesion. Apply Del-Val 320 only to clean, dry, sound surfaces free of loose particles or other foreign matter. For best results, ambient temperature should be between 50-80°F, and relative humidity should be above 20%. Higher temperatures will shorten cure and working times, while lower temperatures and lower humidity will lengthen skin over, tack free, and ultimate cure times. Sudden temperature declines causing dew can prevent adhesion development. Apply at a rate of 1.5 gallons per 100 square feet per coat, with a minimum recommended dry film thickness (DFT) of 25 mils to achieve optimal long-term performance. Skin-over occurs in approximately 30 minutes, it’s tack free in 2 hours, and dry to touch in 6 hours. Cleanup tools with Del-Val Orange Cleaner & Degreaser or mineral spirits. Important precautions include avoiding contamination in sealed containers, storing away from heat/ignition sources/incompatibles, and using only in well-ventilated areas; do not inhale vapor or mist or get on skin/eyes/clothing.
