🖤 Seal it sleek, seal it strong — the black silicone that means business.
ASI 502 is a premium 100% RTV silicone sealant in a convenient 2.8 oz squeeze tube, engineered for professional-grade, non-slump application on any surface. It cures into a flexible, weatherproof rubber that withstands extreme temperatures (-70°F to 400°F) and harsh environmental conditions, while offering FDA-approved safety for incidental food contact. Its sleek black finish blends invisibly on dark surfaces, making it the go-to choice for millennial pros who demand durability, precision, and style in every seal.

Very Easy to Use
This silicone is easy to apply. You do not need a caulk gun or any other tool. You apply it straight from the tube. I found it to be very clean. It has a semi-gloss to satin presentation when dried. I used it to fill some gaps in some black painted wood that I put together and it was perfect. It blended right in with the pained wood. It adhered to the wood very well and filled the gaps seamlessly. It looks great.

Great for kitchen sink seal!
Worked great for our below kitchen sink which is black on black granite. Can't see the seal like the clear silicon that the installers used. be mindful if you use it for this, remember to clean occasionally!

Good product be careful of the bottom coming loose
It was a good product. Problem is the bottom of the tube blew out and stuff got all over everything.

Solid silicone
Needed some to match black grout. Worked out well, tube is easy to use. Smell is typical of silicone. I would buy again but one tube is plenty.

Quality product.
Great product. Dries super fast, is what it says it is, 100%, black. I used it to repair a 30 year old US Divers mask, and am happy with the result.

Easy inexpensive
Messy but works great! It adhered well to an old painted countertop that I lightly prepped by wiping it with a degreaser….no sanding. It needs a tip dispenser with various options for beading to imho. Very nice value for a color that was difficult to find in my local stores. It was easy…I’m a woman who did this project alone and I have no experience caulking. It looks nice and is holding up well around the sink.

I had an old pan that the handle cracked on. Thought this hi temperature silicone might work for a repair. Handle is once again secure and have ran pot through dishwasher several times and silicone looks like new
