HM-2500 Assembly Sealant provides as much immediate adhesion as double-sided, pressure sensitive tape. It then cures to a flexible, weather-resistant silicone seal with outstanding durability and ultraviolet resistance. It provides long-lasting adhesion to PVC, aluminum, painted and treated wood, high-performance paints, plastics and various substrates. It has a long open time and pot life.
