Alternative to Aeroglaze 9700/9743

it appears to be a Socomore not SPS product: https://www.socomore.com/en/curative-component-aeroglaze-9700b-lined-quart.html

Goat, the epoxy primers listed in the epoxy prime process spec at the OEM I work at are:

PPG Desoprime HS: CA7833, CA7502 (chrome free), CA7700, and C7755
Sherwin Williams Aerospace Coatings: SM0483928 (base), CM0120828 (activator)

Most commonly, we use the PPG 7833. If we need chrome-free, then the 7502. We use all of these on both steel and aluminum. Hope this helps.

We are also scrambling to find alternates to things no longer available from the SPS fire.

None of this thread makes sense...

SPS fastener manufacturing has NO relationship to manufacture of epoxy primers. SWC's post clarified this basic truth...

The Issue from Goat... last sentence... "Any suggested alternatives? It is used for both joining and sealing."... implies that they clearly understand that Socomore products are coatings. This fundamental fact is highlighted/expanded-on by Nelle... which makes this posting seem like an advertisement for PPG coatings in disguise.

Wil, you are reading too much into this. I am simply offering possible epoxy alternates for the original poster. I've got no ulterior motives. I am an engineer at Air Tractor. We design and build crop dusting and fire fighting airplanes. We must have robust corrosion prevention measures due to how our airplanes are operated and what they carry (often times corrosive chemicals). We as a company have found these epoxy primers to be robust. I was simply sharing something with the original poster I was hoping would help him out. I am not a PPG salesman and have no affiliations with them, other than knowing they produce good paint. Posts like yours make people like me not want to respond on public forums.

Hello @Stephan Nelle,
I don't think it was meant personally.
It has happened (not too often) that one member asks a question and another answers it - in a blatantly "sock-puppet" fashion. Long-time members like me and Will are wary of these things; we've seen it before. One key sign is a low-time member posting asking for a product recommendation. Another sign is a question with a fairly obvious error in it. Well, check both boxes today.

Hi @Goatcheesepizza,
Sorry to talk about you in the 3rd person like this, and it's probably "got your goat" too. I hope my explanation is helpful to you, too.


It's just the reality of the internet now. Everyone has to be on their guard. (you should be too)

@Sparweb, I know it wasn't meant personally. The assumption that my post was a sales ad in disguise, rather than one engineer trying to help another, is what irked me (temporarily). All Is good.

Back on keel, the SPS factory burning down has caused at least a moderate rippled in the OEM supply chain. We at Air Tractor bought some hardware from them that we've had to scramble to find alternates for. Additionally, SPS made some hardware or parts for PT6A engines that PWC is scrambling to find alternates for, which delays engine shipments to us and others who use their engines. I've read articles about other OEMS with similar issues.
