Purpose & User
Henry 928004 is a solvent-based silicone roofing sealant supplied in a 10.1 oz cartridge. It is formulated for patching and sealing metal roof surfaces where a flexible, waterproof bond is required. The product suits professional roofers and maintenance crews carrying out repairs in variable weather conditions. It is not intended for structural glazing or high-movement expansion joints.
Build & Application
The sealant meets ASTM D412 standards and contains 25 g/L VOC content. It applies cleanly from a standard caulking gun at temperatures between 35 and 120 degrees Fahrenheit. The unfinished black finish blends with common roof membranes and metal flashing. The solvent base allows tooling on damp substrates without sagging on vertical seams. It is not designed for continuous immersion or potable water contact.
Accessories & Compatibility
The cartridge fits industry-standard 10.1 oz dispensers so no proprietary gun is needed. It is compatible with Henry patching compounds for multi-layer repairs on the same job site. No primer, cleaner or backing rod is included in the package. The formulation is unrestricted for sale in all listed states.

Questions about this item
What does the 25 g/L VOC content mean for application?
The 25 g/L VOC level keeps the solvent-based silicone within strict emissions limits while still flowing easily from the 10.1 oz cartridge.
Will the 10.1 oz cartridge fit my standard caulking gun?
Yes, the 10.1 oz cartridge follows the industry-standard size and loads into any full-size manual or pneumatic gun.
How do I apply the sealant at the 35 °F minimum temperature?
Warm the cartridge to at least 35 °F before cutting the tip, then tool the bead immediately — cold silicone skins over fast and traps air if you delay.
