Bob Smith 206 Slow-Cure 9oz Epoxy

This epoxy sets up as described. Come in the two bottles and the mix is 1:1 ratio. No mess bottles and I have had and continue to use the same bottles for several months now. Last a long time without drying out. Works great on many types of surfaces as long as it is clean and dry.

This stuff is amazing. It has a great working time if you need to make adjustments and bonds quite strongly once cured. It remains slightly tacky, so don't use it for a surface finish, but that's great for a mechanical adhesive.

Love this product. I've used a lot of epoxies in the past. 30 minute set time was accurate and perfect for my project.

Excellent epoxy. Mix it right and it cures to high hardness, effectively clear. This is the only epoxy I use. Wish I could buy it in bigger containers. I’ve trusted it for years and it’s been extremely consistent for me.

Nothing else comes close. Easy to apply and cures quickly.

I have used Bob Smith epoxy for about 4 years now. It is fantastic epoxy as far as adhesion and value goes.The only down point is the 30 minute slow cure epoxy is absolutely not 30 minutes of working time. Realistically you only have 15 minutes of working time. After that it gets too thick to use for delicate parts.My shop is temperature and humidity controlled and it is the same issue bottle after bottle. Other epoxies I use do not have this issue. So just plan for 15 minutes of actual working time. I would give it a five star if it was not for the detracted working time. But overall it is an absolutely fantastic epoxy.

Always consistent and lots of working time.Beats all the others and been using BSI epoxies for over 45 yrs. BSI is expensive for a reason. It's the best you can buy!! Don't risk building giant RC aircraft to any other brand.

This 30 minute epoxy was completely hardened in 5 minutes. I hope I got the clamps on in time. It was 95f in my garage where I used it. I expected more working time. And yes, I mixed it properly.
