making high chemical resistance silicone coated gloves


as you know gloves are very impotent for safety.but most gloves are made from rubber (isoprene ,neoprene ,Butyl, Nitrile,) ,not so chemical resistant pvc are good but can't compare with PTFE or Viton. which are very expensive.
we all know silicone has reputation for chemical resistant.but i search for gloves that are made from silicone but they are used for cooking.

then i had an idea to coat normal gloves with silicone sealant.that was a epic failure because it got peeled off quickly.after a while i got my hands on a low viscosity RTV silicone that claiming to stick to rubber.did some tests and t was a success.got my self a long sleeved gloves and put them on. with generous amount of silicone and washed my gloved with them.hang them to dry and after a while put on another coat on top the old one.let it dry and was good to go.tried to see if it will peel off.and no it didn't.

now i have set of gloves that con use with con. NaOH Con. H2SO4 even 70% HNO3. if you try to repeat this work use low viscosity RTV silicone,do a test sample to see whether if it bond to rubber.use well ventilated area as it gives off fumes of acetic acid.get help from another individual as you do this.read instructions in silicone tube.

Here's a handy resource when considering gloves: the Ansell Chemical Resistance Guide https://ehs.unc.edu/files/2015/09/Ansell_8thEditionChemicalR...

It doesn't mention silicone, so I can't say how much more effective it is than other glove types. Interesting idea though.

"now i have set of gloves that con use with con. NaOH Con. H2SO4 even 70% HNO3"

did you test that or it is just an assumption?

tested! ones i used normal rubber stopper make a mold out of POP and made a proto putty https://www.youtube.com/watch?v=7fwytA5r2Mw (used powdered borosilicate instead of corn starch) stopper it worked well for 70% HNO3 and 98% H2SO4.
Grant we miss You!:(
