## Description

ASI Aquarium Silicone Sealant has been specifically formulated for the fabrication of fresh and salt-water aquariums. This high modulus component RTV Silicone Sealant forms strong cohesive bonds to glass without the need of primers. The bonds are unaffected by continuous immersion in water and, when fully cured, is non-toxic to fish. ASI Aquarium Silicone Sealant is a non-slump sealant and can be applied to vertical surfaces without flowing or sagging.High ModulusExcellent tensile strengthExcellent primerless adhesion to glassBond unaffected by continuous immersion in waterExcellent clarityBecause ASIAquarium Silicone Sealant is a 100% silicone sealant, it has excellent resistance to weathering including ozone, ultra-violet radiation and airborne chemicals.ASI Aquarium Silicone Sealant 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 -57°C to +233°C (-70° F to 450°F).MATERIAL PREPARATIONFor successful bonding, glass must be clean of all dust, dirt and oil. The presence of these contaminants may impede the development of the bond. Therefore, it is essential that the glass be cleaned with suitable and compatible cleansers such as nonoily solvents, diluted solutions of acetic acid or extremely hot water. The cleaned glass should be wiped dry immediately with a clean, lint free cloth or blown dry with hot oil free air.DO NOT clean glass with soap and water solutions. Soap residue can act as a release agent and result in adhesion failure.Clean glass should be handled with clean, lint free gloves or equivalent only. Oils from hands and fingers can act a r

## Questions & Answers

**Q: could this be used on panda plastic (poly film) i have a floor/wall covered with panda and want to seal the crack where the floor/wall meet**
A: Our black caulk will fill your crack and then some. In other words, it'll work just fine.

**Q: I placed travertine in my aquarium.  Will thus seal it so water will not get under?**
A: As long as the  material  You are putting in the aquarium is NOT porous and you make sure any openings are closed up this should work for you. Of course how much you use and the depth of your aquarium are factors as well as if you don’t apply enough and if one has a big tank the pressure on the seal could brake.
I use this to make retaining walls for landscaping my aquariums and its been working great for me.

**Q: Will this adhere to cured silicone. I have a spot that seems to be cosmetic and would like to add more.**
A: It will - but it wouldn't be effective. I would scrape off the bad section and apply the new silicone.

**Q: could this seal pvc to abs plastic?**
A: Yes it will. The silicone will adhere clean smooth surfaces.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Works great for aquariums!
*by H***R on August 4, 2024*

I used this when reconditioning my 2006 50 gal aquarium, which has now been setup for a year after application. I used the clear, it's none yellowing and it's still mostly clear. It's actually mostly opaque in the thicker areas and clear in the thinner feathered out areas. It's easy to apply, well maybe not as easy inside of an aquarium, you need to move quickly and not touch the same areas twice. You may also need some paint thinner or similar solvent based thinner to clean up any mess. It's best to just let it dry, and use a new razor blade to scrape any excess off. Just make sure everything is prepped and very clean prior to application. One tube was plenty for the tank, I used 1" blue tape helping with straight lines. It's not necessary, but it does help make things look better. Cures overnight, but I gave it a few days prior to my leak test. They also have black, but I like the clear better on this tank.I'm sure it would be a great silicone for other applications, so use it up before any remaining in an unopened tube cures inside the tube. It's good stuff and well worth the money and your labor!Cheers!

### ⭐⭐⭐⭐⭐ Works as needed and dries pretty quickly.
*by J***E on July 12, 2024*

I used this to water seal some spray foam I put in my geckos 🦎 tank. The product dried pretty quickly for the application I used it for. I cut and sanded the spray foam so The absorbent product I put it on might have been why it dried so quickly. I also didn’t want the glossy look that you get with product so I tried to dust it with some dry soil, but half was already dry & to had to put another layer to get it tacky enough for the dirt to stick on there. This is not the main use for the product, but it works and my DYI project turned out great! And I have a happy gecko, a humid tank and no soggy decor, so I’m satisfied with this product and will use it again if I ever need to!

### ⭐⭐⭐⭐⭐ Works great
*by A***R on August 11, 2025*

Works great in tanks. Resealed my 125 g and it’s still not leaking. Cures fast and holds. Picture is after resealed
