Gordon Glass Co. Clear Electronic Grade Silicone - 2.8 oz Squeeze Tube

I used this primarily to vibration-proof a somewhat-risky component substitution for an obsolete part. I would have liked something that cured a bit stiffer, but it's probably perfectly fine. And making it stiffer would probably make it less general-purpose than it is. Seems like a quality product. Noobs beware - if it smells like vinegar, IT'S NOT FOR ELECTRONICS! Do it right or don't do it. This is the right stuff.

Used it on a drone rebuild and it worked just fine. Also a good value

It works well as a silicone but does take quite longer to cure than say GE Supreme. I ended up putting the project in the garage where it was more humid to help curing time. When I first put the tube away after use, I placed a piece of Saran Wrap (Stretch-Tight actually) between the nozzle and the cap to create an air-tight seal. It started to cure in the nozzle after just a week. The second tine I used it I did the same but also put the entire tube in a ziplock sandwich bag and squeezed out the air. That seems to have done the trick. Next time I opened it two weeks later it was flowing out as if I had a new tube. I'll take everyone's word for the safety around electronics (used in an outdoor LED project).

The ASI 388 clear electronic-grade silicone works exactly as advertised. It applies smoothly, cures evenly, and stays flexible once set. I used it for electronic sealing and insulation, and it adheres well without causing any issues to sensitive components. The clear finish looks clean and professional, and it provides good moisture protection. Cure time is reasonable, though it does take a bit longer to fully set compared to some quick-cure options. Overall, this is a reliable, high-quality silicone for electronics and precision work. Great performance with just minor room for improvement on cure time. Would definitely use it again.

great product, using on circuit boards, would recommend and order again
