Description

Genuine J-B Weld · Part no. 32329A

J-B Weld Ultimate Black Silicone is the black silicone from J-B Weld's Ultimate line, in an 85g tube. It seals and bonds, stays waterproof and mould-resistant, doesn't shrink, sets in about an hour and cures in 24 hours, for weather strips, door frames, window surrounds, mouldings and lamp housings on cars, vans and caravans.

Good to know

• Is the Ultimate version rated for engines? The facts here list the same body and trim uses as the standard silicone and give no heat or oil figures, so check the tube before using it on an engine joint.
• What's it good for on a van or caravan? Re-bedding weather strips, sealing window surrounds and roof fittings, and stopping water getting in round lamp housings, with a black bead that matches the rubber.
• How do I get a neat finish? Mask both sides, lay one continuous bead, smooth it with a wetted finger or tool, then lift the tape before it sets.

Which one?

For a grey bead against light trim or castings, J-B Weld Ultimate Grey Silicone (32327B) is the grey version; for a gasket maker that gives heat figures, Loctite SI5980 Silicone Flange Sealant – Black (2064235).
