Without it being specifically stated, I'd contact the manufacturer directly. Could do some funky chemical business when mixed.
Hopefully this isn't about bonding motor retainers? You want the regular JB at full strength for that purpose.
(tangent question)
What type of rocket airframe/fin materials is it?
JB weld may be what you have on hand, but it's a pretty heavy adhesive (steel powder!) and there are likely other products at hand that would do just as good a job for your fins.
Bob Smith is a common hobby brand, Red Baron may be another one (not sure if its still around or was re-branded Bob Smith). Many hobby shops sell Bob Smith epoxy and CA under a house label, I have the 5 and 15 minute sitting on my work bench now and its labelled Hobby Town but on the back it says www.bsi-inc.com
JB is a paste, the BSI epoxies are like honey, and will require thickening with the previously mention cabosil, wood flour, micro ballons or talcum powder ( some baby powders are talcum, just make sure and read the ingredients, cornstarch baby powder will not work). Thicken to the consistency of peanut butter.How viscous is it compared to JB? I've only used JB-Weld and Kwikweld in the past, but I think something that flows easier might be useful for fin fillets.
30 minute for filleting, it takes a little longer to mix the larger quantities for fillets and to add the amendments for thickening.Cool. Would you recommend the 15 minute or the 30 minute version?
Is thickening required or can it be used as is?JB is a paste, the BSI epoxies are like honey, and will require thickening with the previously mention cabosil, wood flour, micro ballons or talcum powder ( some baby powders are talcum, just make sure and read the ingredients, cornstarch baby powder will not work).
