## Overview

ASI 502 Silicone Sealant is a premium 100% RTV moisture-curing silicone in a convenient 2.8 oz squeeze tube. Engineered for professional-grade durability, it bonds to a wide range of surfaces without sagging, cures to a flexible rubber that resists extreme temperatures (-70°F to 400°F), weathering, and chemicals. FDA-approved for incidental food contact, this clear sealant is ideal for long-lasting, waterproof repairs on vertical, overhead, and hard-to-reach areas.

## Description

ASI 502 is a 100% RTV Silicone that is UL & NSF Recognized. ASI 502 is a one-part, moisture-curing RTV (room temperature vulcanizing) silicone that cures to a strong, silicone rubber that maintains long-term durability and flexibility. ASI 502 100% RTV Silicone is a non-slump sealant and can be applied to vertical or overhead surfaces without flowing or sagging. Because ASI 502 is a 100% RTV silicone sealant, it has excellent resistance to weathering including ozone, ultra-violet radiation, freeze-thaw conditions and airborne chemicals. Fully cured, ASI 502 has excellent adhesion to glass, metal, porcelain, ceramic, wood, most plastics and many other nonporous substrates.ASI 100% RTV Silicone (ASI 502) can be applied to surface temperatures from -18°C to +50°C (0°F to +120°F) and after curing, withstands constant operating temperatures from -70 to +400 degrees F.Typical Uses: ASI 502 is an excellent sealant and/or adhesive for many applications where a long-term, permanently flexible bond or seal is required.

Review: Unbelievable, water resistant, clear, long lasting glue works on any surface - This sealant/glue is amazing. During the rain my metal porch roof had a crack in it. I dried it off as best I could and put this amazing glue in the crack like magic. The roof stopped leaking. It dries quickly, it is water resistant and it is the best quality glue around. It is also clear; so you can put it on different surfaces. I saw the spectrum technician use it when he came over to fix a leak. The price is amazing. It saved me hundreds of dollars in repairs.
Review: Very Satisfying! - It fixed a broken sealant valve that was leaking on my Delonghi coffee maker which would have cost $1500 to replace. Then it fixed an old 10-gallon water jug that was falling apart and threw $5 plastic laundry baskets. I still have have a tube left and I wish I had more broken things to fix. I heard about this product on the No Agenda Podcast that ends each episode with a tip of the day from John C Dvorak. Thank you!

## Questions & Answers

**Q: I want to seal a tree slice to place candied apples on. Will it dry clear?**
A: Yes, this is Clear Food Grade Silicone Sealant.

**Q: Is this real, odorless RTV, or does it have an acetic/vinegar smell like most silicone sealants?**
A: I didn’t experience any of odor or acedic/vinegars smell/taste from this product.

**Q: Will it seal a savino wine saving tritan plastic carafe? apparently the carafe is in two pieces snapped together tightly and frequently leaks.**
A: Not sure about chemical burn issue.  I manipulated the silicone around the hole in the carafe with a toothpick.  The only caveat on the tube it comes in says - "Caution:  On contact, uncured silicone sealant irritates eyes. Flush eyes with water.  Call Physician immediately.  Sealant releases acetic acid during cure."   Acetic acid is the main component of vinegar.  You could also use disposable nitrile exam gloves (usually comes in a box of 200) to put a barrier between your skin and the the sealant.  I use those (gloves) all the time for stuff I have to around the house where I want to protect my hands but still have good fine motor control (impossible with regular work gloves).  Good luck!

**Q: I assume this is suitable to caulk around a kitchen sink and faucet?**
A: Yes this fine around the sink and faucet in the kitchen.  This product works very well.
