Use of Alodine
Hi everyone,
I have a couple of questions for our priming experts.
Because the UK is a very wet island, and because I want my future plane to hold its value as best as possible, I have decided to be cautious and prime thoroughly. At the same time I want to stay clear from toxic products and not add too much weight to the plane. I am planning on using Stewart System's (a combination of EkoClean, EkoEtch, EkoPoxy/EkoPrime) which seems to do the job.
Although Stewart System does not mention it (as far as I can tell), I have read in some places that parts should be dipped in alodine before priming. This was initially a non-starter for me as I thought the product contained chromates. However I was referred to this product (Henkel Alodine 5700) which looks like a (relatively) harmless alternative.
My questions:
- Is there a risk that this could have an adverse effect on the efficacy of EkoPrime/EkoPoxy? I'll probably check with Stewart Systems directly.
- Would it improve corrosion protection if I dipped aluminium/steel parts if I decided to use it, or is that completely overkill?
- If I decided to do this, what would the process be? I assume "Clean -> Etch -> Dip -> Prime"?
- I have seen some people saying they dipped their rivets in alodine. Is it a good idea?
Thanks in advance for your support.
