Best Super Glue!
I really like this Super Glue because I have been able to use it over and over without it plugging the nozzle, which is what normally ruins super glue. I have had the previous bottle for 3 years before it plugged. To Super charge this glue even more, add some graphite powder, (either graphite lubricant powder or just run a pencil over sandpaper) and mix with the super glue in about a 50-50 mix. After ruffing up the surface you want to glue, add the mixture. once everything is in place you can even put a small dose of baking soda over the top to accelerate the curing (but you won't have much time after putting on he baking soda so be ready!). This mixture is incredibly strong!

Super Stfong Adhesive
I love it, let dry longer for better strength. Yes, its only a half full bottle but its a great strong adhesive. It is runny so get the gel one if you need that. No complaints here. Definitely worth it.

Strong adhesive especially for high temperature
I tested this product against a similar instant adhesive from a competitor. I needed something that had a quick fixture time around 5 to 10 seconds and hand excellent bond strength up to 140 degrees. 401 is rated up to 225 degrees F and the other adhesive I was using was only rated to 185 F. I tested the bond strength between my parts using an Instron machine and this adhesive had almost double the strength of the competition at both room temperature and 140 F. This is my new go-to adhesive at work and at home now.

This is a good glue and provides a good bonding for plastics. But, exactly plastics it sticks and which not, that information is either not available on the bottle or is in very very fine print. However, in some cases, the glue did not stick the plastic or the joint broke in one or 2 normal usage of the glued pieces. Don't know the reason for it.

this adhesive seems to repair almost all kinds of plastic. Reminds me of Crazy glue tha way it stuck my fingers together
