A silicone rubber potting compound is used to insulate or conceal electrical circuitry in professional and industrial applications while in the testing phase. AeroMarine silicone potting compounds are made from a platinum based two part silicone rubber.
Once cured, our silicone rubber potting compound can shield your circuitry from vibration, debris, and moisture.
Shake the 2 sides well for up to 10 minutes. Pour equal parts of A and B into separate containers. Mix both parts together in an additional clean plastic container. Use a plastic or metal stirring utensil to thoroughly mix the silicone rubber potting compound. To ensure that the compound is well-mixed, be sure to scrape the sides of the container and to stir from the bottom. Mix for several minutes until the rubber potting compound is a uniform color.
Use a small brush to apply a light layer of silicone potting over your circuitry or device to break the surface tension and help prevent air bubbles. Pour the remainder of the silicone into one corner of the box so it can spread naturally throughout the area.
Do not use latex gloves when you’re mixing the rubber potting compound or applying it, because latex may inhibit the curing process. Curing should take about 12 hours. Certain materials will cause inhibition or neutralizing of the curing agent. These materials are sulfur and organo-metallic salt containing compounds found in organic rubbers and many condensation cure RTV, chloride solvents – amines. Avoid using latex gloves and Tin/Condensation cured RTVs. Inhibition may easily be determined by brushing a small quantity of this material over the surface and allowing it to cure. If material remains tacky and gummy after the curing time, then the part’s surface is acting as an inhibitor.
AeroMarine’s silicone rubber potting compound is used when do the initial testing for new components so it can be removed from most things. There are a few different ways to remove it. You can gently separate the silicone from the parts with an art blade or putty knife. If there is resistance you can use solvents to help remove some of the outer layer of silicone. Be careful not to cut into or damage the internal parts during the removal process.
