Improve productivity and efficiency in your window, door, and structural applications with RapidStrength sealant. This two-part, 100% silicone sealant builds strength immediately and typically reaches full cure in less than a day. It forms a strong, flexible, weathertight seal for lasting indoor comfort.
With RapidStrength sealant’s quick green strength and fast, deep-section cure rate, you don’t have to wait long to handle units. Its work life is adjustable, allowing you more precise control over production speed. And because it is 100% silicone, doors, windows, and other applications are exceptionally resistant to heat, cold, UV exposure, rain, snow, and wind.
RapidStrength sealant can securely bond without a primer to most conventional substrates and finishes, including glass, polycarbonate, vinyl, plastics, aluminum, and treated and untreated wood.
