High-strength adhesion. Exceptional flexibility.
Built for demanding construction environments.

One Product. Two Critical Functions.
StormLock™ is a professional-grade advanced hybrid adhesive/sealant engineered to deliver strong, durable bonding together with the flexibility required for long-term sealing performance. Designed for demanding interior and exterior construction applications, StormLock provides exceptional adhesion across a wide range of building materials while accommodating ±50% joint movement caused by expansion, contraction, vibration, and changing environmental conditions.
Its rapid-cure hybrid formulation offers fast skinning, a 24-hour cure, and long-lasting UV and weather resistance, helping create durable, weather-tight seals in applications where performance and reliability matter. From windows and doors, storefront systems, expansion joints, precast construction, roofing, siding, fascia, parapets, HVAC/R, plumbing, and exterior trim to a variety of specialty construction uses, StormLock gives contractors and installers a versatile solution for both bonding and sealing.
StormLock combines the holding power of an adhesive with the flexibility and weather protection of a high-performance sealant, helping reduce the need to choose between strength and movement capability.
