Yellow Ceconite 102

[1938BF50]

I have a partial roll of yellow Ceconite 102 that is heavier and stiffer that std white 102. I can't find anything online that refers to the yellow color. Any ideas?

Maybe a pre treated or pre doped material?

I believe that is the old Blue River system fabric. I would not use it.

I came across this yellow Ceconite about 30 years ago (although it was in 2" pinked tape form). As others have said, I think it's pre-doped. Quite how to use it, I didn't know back then, so I discarded it, but I now believe it to be applied with Nitrate thinners (no dope required). This was before the "New Super Seam", when Ceconite used Nitrate-based adhesives.

It's "pre-preg" and terrible stuff!!! It's not even worth trying!!! I remember throwing probably 50+ yards away!!!!

Blue River fabric. Not sure I would use it.

Well, I had already covered my gear legs before I got this feedback. I will say, it bonded with New Super Seam cement beter than anything I have ever used. It shrank up just fine as well. Because of its stiffness, I made gear leg covering templates out of the remainder. Thanx formall the input!

It wont last, a previous customer got 4 years out of the cover job using blue river before he had to recover it...the nitrate will peel of because it will not encapsulate the fabric correctly. It was good in theory but bad in practice. Replace it now or in a few years, but you will replace it. Tim

So is the "yellow pre-preg" fabric the Blue River process? Or am I confusing colours with names of processes?

It was towards the end of the "Blue River" process, Rob.

Is the Stewart Systems process an adaption of the former Blue River process or have I mixed up the origins of either?

The Stewart System is not the same as the Blue River. Water is used as a catalyst in the Stewart System, otherwise nothing in common. And that is from Stewart Systems information I got at a learn to do it class. Stewart's is nice to work with.

Water is used as the carrier not the catalyst.
No, there's nothing left of the Blue River system in Stewarts. At one point, it was a rider on the BR STC, but that was a long time ago and it's on it's own STC now, under part 23 standards. The only thing that was from any other system is the fill coat (ekofill) and that came from the old Eonex system.

This post is all them more reason that I am sticking with Polyfiber..

[Robert Lees]

I prefer Polyfiber myself, but most of my Customers require Ceconite. I'm equally conversant on both.

I'm awaiting a Customer who wants Stewarts so that I can try it !
