Also, it was seeping into the cracks and crevices, not getting an even coverage.]]> http://www.dakkadakka.com/dakkaforum/posts/preList/549090/5998484.page http://www.dakkadakka.com/dakkaforum/posts/preList/549090/5998484.page GMT Krylon Primer melts plastic models?

is it actually melting the plastic or was it just applied so heavily that it obscures detail? someone posts about krylon melting things all the time, but so far it's almost always been put down to user error iirc

I use Krylon Fusion paints exclusively when I can, and I have never noticed any "melting". It comes out strong, so try not glopping it on so much. Stay at least 6" away from the mini and spray in passes. Start before the mini, push down, then move the nozzle past quickly.

I don't see how it's "melting" your models. Can we see pics? ]]> http://www.dakkadakka.com/dakkaforum/posts/preList/549090/5998510.page http://www.dakkadakka.com/dakkaforum/posts/preList/549090/5998510.page GMT Re:Krylon Primer melts plastic models?

After a few minutes of drying, the plastic turned to a darker grey. ]]> http://www.dakkadakka.com/dakkaforum/posts/preList/549090/5998511.page http://www.dakkadakka.com/dakkaforum/posts/preList/549090/5998511.page GMT Re:Krylon Primer melts plastic models? http://www.dakkadakka.com/dakkaforum/posts/preList/549090/5998521.page http://www.dakkadakka.com/dakkaforum/posts/preList/549090/5998521.page GMT Krylon Primer melts plastic models? Did we accidentally use an epoxy primer? Self etching primer? Enamel or lacquer primer? These types of materials are very hazardous to our models, and would immediately begin melting them down to squishy little puddles.

I prime my models Exclusively with that exact can (and it's grey/black counterparts). Plastics, metals, resins, from a variety of model companies.
Never any melting for me.

I must also insist on images of your models. Lets see the melting in action, because I've also got to be thinking that you've over-applied and it's just glooped on there that it looks like a wax figurine on a heater.

I apologize, if they really are melting, then that really sucks. But I have a very difficult time accepting it.]]> http://www.dakkadakka.com/dakkaforum/posts/preList/549090/5998568.page http://www.dakkadakka.com/dakkaforum/posts/preList/549090/5998568.page GMT Re:Krylon Primer melts plastic models? ]]> http://www.dakkadakka.com/dakkaforum/posts/preList/549090/5998582.page http://www.dakkadakka.com/dakkaforum/posts/preList/549090/5998582.page GMT Krylon Primer melts plastic models? GW plastic with a can of spray paint.

Except to do so you either have to be misusing it VERY badly, or you have to have gotten a TERRIBLE batch with like all solvent no paint.]]> http://www.dakkadakka.com/dakkaforum/posts/preList/549090/5998621.page http://www.dakkadakka.com/dakkaforum/posts/preList/549090/5998621.page GMT Krylon Primer melts plastic models?
Between the propellants and the solvents in the paint, there are plenty of chemicals that happily dissolve styrene. Same reason you dont generally want to spray stuff like styrofoam with them...

However, when used properly, you can use almost any aerosol paint on almost any plastic without having significant melting going on. Lighter coats, further away is the best place to start. Most the chemicals of concern have a very low vapor pressure, so as soon as they are exposed to the air, the start to disipate. If you provide a good 8-12 inches of travel and dont use it too heavy, the vast majority will be gone before it lands on the model. The rest, although it might melt the very surface will not actually damage the model (it is one of the reasons you get permanent staining from some primers on pkastic though).]]> http://www.dakkadakka.com/dakkaforum/posts/preList/549090/5998867.page http://www.dakkadakka.com/dakkaforum/posts/preList/549090/5998867.page GMT
