How to Silicone Rubber Coat Metal

Silicone rubber has many ideal properties when coating metal tools and other objects.
It can greatly improve your tactile grip and reduce the risk of tool drop.
Because it is a bad thermal conductor and an electrical conductor, it is very useful in protecting you from a thermal conductor or a charged conductor.
It is not complicated to coat the metal in silicone, but it does take a few steps in advance to ensure a good combination.
Rate the metal surface you want to cover with a grinder, metal file or other tool.
These scratches will allow the silicone rubber area to catch.
Pour into the bowl fast enough
Cure the silicone base and drown out the metal you want to cover.
If the silicone is mixed with the catalyst by weight rather than volume, the weight of the empty bowl is subtracted from the total weight to infer the weight of the silicone.
Mix the catalyst into the silicone base according to the mixing ratio on the container.
Most silicone has a ratio of 10:1 or 1:1 by weight or volume.
Thoroughly stir the silicone base and catalyst to ensure there is no unmixed area.
Scrape the sides and bottom of the bowl several times with a mixer stick.
Add a few drops of contact agent to the mixed silicone to make it thick.
Mix it fully.
When silicone is cured, thickening of silicone can greatly reduce drops.
Dip the score part of the metal into the thickened silicone and pull it out directly.
Immerse and remove the metal slowly to reduce the risk of capturing bubbles on the metal.
Hang the metal on the clothesline and let the silicone cure for 24 hours.
If necessary, fix it in place with tape.
