Hey I'm looking to coat some 0.5" aluminum rods with some sort of coating to increase the friction coefficient ("tackiness" I believe it's called). It will be used in high temperature environments of up to 200C. Does anyone know of such product?

I tried calling this company but that product can't get anywhere near 200C.

A high-temperature silicone?

It's just that silicone won't adhere to aluminium. Maybe things get less bad if you anodise first.

My suggestion is a nickel layer. These have a high coefficient of friction, and better, they don't gall.

You already know that aluminium alloys are capable of nearly nothing at 200, do you?

Need high-temp rubber coating

could try a belzona coating depending on what your doing

They are usually painted on smooth, but I can imagine you cant make it rougher when you apply it. Also expensive but good for temps up to 180C
