Water-based acrylics can be painted, can be cleaned with water, and require less surface preparation than solvent- and silicone-based caulks and sealants. Water-based acrylic caulks and sealants have less of an odor than solvent- and silicone-based products. Solvent- and silicone-based caulks and sealants are generally more flexible than acrylics and can withstand more sunlight and temperature extremes. They require solvents to clean, are more difficult to remove than acrylics, and generally cannot be painted. Water-based acrylic caulks and sealants with added silicone offer a variety of features, depending on the specific formula.Momentive manufactures chemicals and materials such as ceramics, resins, silicone, adhesives, and sealants. The company is headquartered in Columbus, OH.

Review: Used to hold capacitors in place on PCB - Used this to hold capacitors in place on a power supply PCB, after the original capacitors were replaced. It looks to be similar to the original adhesive used on the board. Works fine, if a bit expensive.
Review: Excellent PCB type adhesive - This stuff is great. It doesn't go extremely far, but it does exactly what you expect. Great holding, fast setup, easy removal with no damage. Worth it for expensive projects.

### ⭐⭐⭐⭐⭐ Excellent PCB type adhesive

This stuff is great. It doesn't go extremely far, but it does exactly what you expect. Great holding, fast setup, easy removal with no damage. Worth it for expensive projects.

### ⭐⭐⭐⭐ Works great for electronics. Just takes a lot longer to dry than I would like.
*by P***R on 10 December 2012*

This RTV is good for insulating components against show or to reduce vibration or whine. It's just not very tacky and takes a while to set, so be forewarned.
