Dow Corning 4098499 Rtv Silicone Joint Sealant 3 Oz Clear

Product Description

The DOW CORNING 4098499 is an RTV silicone joint sealant packaged in a 3 oz cartridge, part of the 737 series. It cures at room temperature to form a flexible, durable seal rated for continuous service from -85 degrees F to 350 degrees F. The clear formulation leaves a clean, low-profile bead and is paintable after cure. Full cure is reached in 24 hours with a tack-free dry time of just 14 minutes. Plumbers, HVAC technicians, and maintenance professionals use this sealant where a food-safe, multi-surface silicone bond is required in demanding environments.

This sealant is suited for both residential and light commercial applications where reliable sealing is needed on glass, metal, painted surfaces, plastic, and rubber substrates. The 737 series is commonly applied in HVAC ductwork, plumbing penetrations, equipment enclosures, and food-processing adjacent installations where food-safe certification is a project requirement. The 3 oz cartridge size is practical for smaller patch jobs and detail work.

Installation Notes

Application is typically performed by HVAC technicians, plumbers, or maintenance personnel using a standard cartridge caulk gun. Surfaces should be clean, dry, and free of oil or loose debris before applying the sealant bead. Allow a minimum of 14 minutes for the surface to become tack-free before handling, and allow the full 24-hour cure before exposing the joint to operating temperatures or fluid contact. Do not apply over wet surfaces or in standing water.
