Ethyl acetate, thicker then Tenax 7R?
Posted by electrolove on Saturday, October 14, 2006 1:20 AM
I have tried to find MEK here in Sweden and it's impossible because it's not allowed here. But I got some information on a Swedish forum that Ethyl acetate can be used instead. And it's very easy to find.

My question to the forum is: How thick is Ethyl acetate compare to Tenax 7R? The problem I have right now is that Tenax 7R is too thin and will flow too fast from my needle applicator bottle, even with the thinnest needle. So I need a thicker glue to make it flow slower.

This is my needle applicator bottle:

Here's some viscosity facts for you:

MEK ... 0.42
Ethyl Acetate ... 0.51
Water .... 1.0

I couldn't find a figure for Tenax 7R, but I suspect it's less than MEK, more like 0.3 something. If that's the case, then Ethyl Acetate should be almost twice as viscous as Tenax.

Here's a trick for you ... if your solvent is too thin, then pour some of it in a small jar with a lid and drop a styrene shaving in it and let it disolve over night. The more styrene you add to the thicker your cement will get ... and of course if you use colored styrene, it will tint your solvent. Another possibility is to get a tube of the thick clear styrene cement and stir a couple drops of that into your solvent to make it a little thicker.

There are always ways to get what you're after! Smile,Wink, & Grin [swg]

I just ordered 1 litre of Ethyl acetate from my local drugstore for around 13 USD. It's here in a couple of days. I think that will be enought glue for a lifetime... The people at the drugsture was very curious what I was going to use it for. So I said, I'm not going to drink it, just glue plastic kits... Smile,Wink, & Grin [swg]
