Kitchen and bath silicone sealant

DAP 8648 is a clear, 10 oz cartridge silicone designed for kitchen and bath applications. It meets FDA 21 CFR 177.2600 standards for food-contact surfaces. Homeowners and professionals use it to create flexible, waterproof joints around sinks, tubs and countertops. Buyers needing a paintable latex caulk or a larger bulk container will need a different product.

Thermal range and cure profile

The sealant remains flexible across a service range of -40 degrees F to 350 degrees F. It develops a skin in roughly 5 minutes and reaches full cure in 1 day under normal conditions. The cured bead resists mildew and mould growth in damp environments. Installers working in extreme cold or requiring faster full-strength cure times should verify suitability.

Cartridge format and compliance

The 10 oz cartridge fits standard caulking guns for controlled dispensing. FDA 21 CFR 177.2600 compliance confirms the cured material is safe for incidental food contact. No separate primer, tooling agent or cleanup solvent is included in the package. Users seeking colour-matched options or specialised applicator nozzles must source them separately.

Questions about this item

How do I load the 10 oz cartridge into a caulk gun and prepare the nozzle?

Insert the cartridge into the gun, pull the plunger back, cut the nozzle tip to the desired bead size, and puncture the inner foil seal before applying.

Will the cured sealant need to be replaced due to mildew or mold growth in a kitchen or bath?

The silicone is mildew resistant and mold resistant, so it resists fungal growth; replacement is only needed if the bead is physically damaged or adhesion fails.

At what temperature does the sealant stop performing during continuous high-heat exposure?

Maximum performance temperature is 350 degrees F; sustained heat above that limit can degrade the sealant.
