Title: Nitrate dope and Lusterkote
Post by: Phil Coopy on August 02, 2006, 10:45:51 PM

Just found out the hard way that Lusterkote doesn"t stick to nitrate dope without primer. Question does it work with primer? Possibly if I mix in some MEK?

I've used Butyrate without primer and had no problem with Lustrekote. I haven't tryed Nitrate with or without primer.

Well I'm back to the nitrate coat....the adhesion was so poor that the Lustrekote peeled off like a layer of plastic wrap. Fortunately the only part I painted was the fuse on my Ringmaster (before assembly). The paint job looked great until I pulled off some masking and the color basecoat came with it.  I'm gonna' go conventional and use dope this time.

I have stated this a few times. Lacquers are chemical bond and enamels are mechanical bond. You must have a primer between the two. (or a trick)

Epoxies are a chemically activated mechanical bond type paint. Most Epoxies are activated with MEK. The MEK is sometimes hot enough to act as a chemical bond. So you get both property's in one application.

This is one reason I use lacquer thinner in my Urethane applications.

Lustrekote goes over dope just fine, but you are correct, you cannot dope over Lustrekote, it won't stick and you have a mess.
Sparky knows all the techy info on this one.
