What this product is

This is an 80mL tube of black RTV silicone adhesive sealant supplied under the Loctite brand. It cures at room temperature to form a flexible, waterproof bond on a variety of surfaces. The product is classified as a cloth tape type sealant for general repair and sealing tasks. It is intended for users who need a durable, heat-resistant adhesive for automotive, plumbing or household applications.

What to check before ordering

Verify that the substrate materials are compatible with silicone chemistry before application. Confirm that the 80mL volume is sufficient for the intended joint size or repair area. Note that this product carries a California Proposition 65 warning regarding reproductive harm. Ensure the work area is ventilated and that surfaces are clean, dry and free of oil for proper adhesion.

How it fits into a build

The sealant functions as a standalone adhesive that requires no mixing or special tools to apply. It creates a permanent, flexible seal that resists vibration, moisture and temperature cycling once cured. The black colour blends with dark surfaces for a discreet finish. It replaces mechanical fasteners or gaskets in non-structural joints, freeing up design space and reducing assembly time.
