LoctiteInstant Adhesive, 401, Prism, 20 Gram Bottle

I believe I first tried this glue when it came with a replacement cv boot for a car I was working on. I was impressed that the glue was durable and flexible enough to be used to bond the seam on the urethane rubber boot, so I began using it for other purposes as well and found it to be exceptionally versatile and generally equal to or better than the other type of superglue for almost all applications. I think it is less brittle and less prone to cracking then regular superglue and that seems to be the main advantage. Also, based on what some of the other reviews said, it is also uniquely useful for bonding silicone.The drying time is similar to other cyanoacrylate based glues - very fast, especially on your fingers. The consistency is a little thicker than water thin superglue, but it is not as thick as gel superglue. Although, I have had a bottle that thickened up with age to the point where it was about the consistency of gel superglue.Like most superglue, you need to be careful to clean the end before putting the lid back on otherwise it can get to the point where the bottle is unusable (or you have to poke a needle in to get the glue to come out).It is a solid choice for first aid superglue. I've used it for that a lot (along with ribbon or masking tape). I've also had success using it for tile repair, repairing nylon plastic parts (including full submersion parts in a dishwasher), repairing cracked muck boots, and many other applications.

Will repair almost anything very fast.

This stuff is some of the strongest and fasting acting glue I have used. Bought it for one project and have used it for several others. Good stuff.

Fast shipping and as described.

Works much better than Super glue. I gave only used it to glue two pieces of vinyl (edge to edge). I held it together for about 30 seconds and it is still holding after about 6 months.The product is just as thin as Super Glue, but it works much better.The downsize is that it hardened in the bottle (just like Super Glue) after I went back to use it about 3 months later. ☹️

I work a lot with adhesives for a living, and we use the 4011 medical version of this in a lot of products. I've had the chance to actually test dozens of adhesives head to head and this one is by far the best. So much so that I ordered some for use at home as well.

Works just as well on glass-filled and carbon filled 3D printed parts. Do not OVER USE. Just a few light drops, then a casual surface smear. The glue chemical reaction will generate a lot of heat for 15 -30 seconds. Using to much not only will not bond as well but can also warp a 3D printed part from the high local heat. Will burn (thermal burn) if it gets on your skin. Permanent bond within 3-5 seconds - so very little time to align the parts. In most cases, the 3D printed part would break before the adhesive bond would fail.

Bonded EDPM ball to Delrin (endpen for upright bass). Roughed up surfaces with sand paper and washed with acetone. Gotta work fast - sets quickly. Holding firm under my bass via daily usage for a month. So far so good.
