Food-Grade RTV Silicone Sealant

ASI 502 is a one-part, moisture-curing RTV silicone supplied in a 2.8 oz squeeze tube. It cures at room temperature to a durable, flexible rubber that resists weathering, ozone and UV exposure. The formulation meets FDA Regulation 175.105 for incidental food contact.

For General Sealing and Bonding Tasks

Suitable for users who need a non-slump sealant on vertical or overhead surfaces such as glass, metal, ceramic, wood and most plastics. Operates on surfaces from -18°C to +50°C and withstands -70°F to +400°F once cured. Not for buyers who require a structural adhesive for load-bearing joints or a product certified for potable water systems.

Check Surface Compatibility and Cure Conditions

Verify that the substrates are non-porous and clean for proper adhesion. Confirm the application temperature falls within the stated range and that the joint design allows moisture access for curing. Ensure the white colour matches the aesthetic requirements of the finished assembly.

Questions about this item

What surfaces should I already have clean and ready before applying the 2.8 oz tube of ASI 502 White RTV silicone?

Prepare glass, metal, porcelain, ceramic, wood, most plastics or other non-porous substrates; the sealant bonds to these materials once fully cured.

Can I use this 100 % RTV silicone alongside existing cured silicone beads in the same joint?

Fresh ASI 502 will not fuse chemically to old cured silicone; remove the old bead completely and clean the joint before applying the new sealant.

How do I confirm the 2.8 oz White ASI 502 has cured properly after installation?

The material turns into a tough, flexible rubber that resists ozone, UV, freeze-thaw cycles and airborne chemicals while staying bonded from -70 °F to +400 °F.
