Food-grade silicone sealant

ASI 502 is a 100% RTV silicone supplied in a 2.8 oz squeeze tube. It cures at room temperature to a flexible, durable rubber that resists weathering, ozone, UV radiation and freeze-thaw cycles. The formula is non-slump, so it stays in place on vertical or overhead surfaces. It carries FDA regulation 175.105 clearance for incidental food contact.

Replaces generic caulks and non-food-grade silicones

The jump is worth it when you need a sealant that remains permanently flexible from -70 to 400 degrees F and meets NSF and UL recognition. It bonds glass, metal, porcelain, ceramic, wood and most plastics without sagging during application. Choose this over standard adhesives when regulatory compliance and long-term temperature stability are required.

Check substrate compatibility and cure conditions

Verify that the surfaces are nonporous and clean for proper adhesion. Application surface temperature must be between -18°C and 50°C (0°F to 120°F) for the moisture-curing process to work. Ensure the joint design accommodates the non-slump paste consistency and that incidental food contact approval matches your use case.

Questions about this item

What size squeeze tube does the ASI502RTV2.8Clear adhesive come in?

The product is supplied in a 2.8 oz squeeze tube, suitable for precise application on vertical or overhead surfaces without sagging.

How do I apply and cure this one-part RTV silicone sealant correctly?

Apply directly from the tube to clean, dry surfaces between 0°F and 120°F; it cures by reacting with atmospheric moisture to form a flexible rubber seal.

When will the cured sealant need replacement in a food-contact application?

The FDA 175.105-compliant sealant resists weathering, UV, and freeze-thaw cycles; inspect periodically and replace if adhesion fails or the rubber degrades.
