Dap 08646 100% Silicone Sealant 10.1 Oz White

Product Description

The DAP 08646 10.1oz dow wht is a 100% silicone sealant formulated for professional-grade sealing applications in HVAC, plumbing, and general construction. Silicone-based sealants in this category provide a flexible, waterproof bond that resists temperature extremes, moisture, and UV exposure after cure. This cartridge is sized at 10.1 oz and is intended for use in a standard caulking gun. The white finish makes it suitable for interior applications where appearance matters, such as around fixtures, penetrations, and mechanical equipment housings. Trade professionals rely on 100% silicone compounds for joints that must maintain integrity through repeated thermal expansion and contraction cycles.

This sealant is appropriate for residential and light commercial applications where a durable, flexible seal is required. Typical uses include sealing around pipe penetrations, HVAC equipment access panels, plumbing fixtures, windows, and other areas requiring a watertight or airtight joint. The white color suits installations where the sealant bead will remain visible after completion. Plumbers, HVAC technicians, and general contractors will find this cartridge format convenient for standard caulking gun application on the job site.

Installation Notes

This product is installed using a standard caulking gun; cut the nozzle tip to the desired bead size before application. Surfaces must be clean, dry, and free of dust, oil, and old sealant before applying. Allow adequate cure time before exposing the joint to water or mechanical stress. Ensure adequate ventilation during application, as silicone sealants release acetic acid during cure.
