Acrylic Flat-Coat recommendation
« on: Mon Dec, 19, 2016, 10:59:AM »

   I have been using Vallejo Matt Varnish and was not at all happy with it .
        ...   their Satin is seemingly more flat   ???

    Anywaze  ,
                           I asked around and AK's Ultra Matt appeared popular  -   so I ordered some

            &  AGREED  ,
                                if you are looking for a great  , super-flat acrylic clear-coat
                                                      look no further   ;D

                         
                          Straight into the cup  , no thinning nec and a one coat Mega-flat    :

Dunno, I look at both bottles sitting on my shelf, and the matt clearly has more flattening agent in the bottom of the bottle.

Which were you using? The 17ml bottles that are in the Model Color and Model Air line up? Or the Urethane version that comes in the 60ml bottles?

This is a picture of the 2 bottles on the shelf here, one on the left is the Satin, which barely has any flattening agent in it, while the matt on the right, the flattening agent is well past the bottom lip of the label. (the one on the far left is the gloss which has none of the flattening agent)



Personally I don't care for the type that comes in the MC and MA line, much prefer the urethane. It is a little thick in the bottle, but cut it 50/50 with AB thinner and spray. Multiple coats where needed.

I have found the matt to be very flat looking. After laying down the gloss to put decals on an aircraft, and then following it up with the matt, you could see it turning matt as it dried, as I was airbrushing it on.

It's just a personal observation on my part , Scott .
  But
Real important ,
  this is Vallejo Model Color  ,  as I said   - 100% acrylic .

Urethanes are a different resin , they actually " cure " via urea bonds and hydrogen bonding  .

I was - still am - using these guys  :      ( I've never used the hybrids or pure urethanes  )

                   

 The AK Ultra Matt is 100 % acrylic  , like the Vallejo ,
But I don't need to thin it at all to spray it
and the stuff is unquestionably dead-flat in one coat  ,
 so ,
It's exactly what I was looking for .

Ahhh yeah, those are the ones I was referring to. Never have cared for them that much.

The polyurethane version they sell is 100X better. I was very impressed at how well the matt worked as the gloss was disappearing as I sprayed the matt on.

Gives a tougher, more durable finish as well, much like the Vallejo primers.

Yeah man the polyurethane clears from Valejo are the nicest clears to work with, they lay down super nice. Can say without a doubt they're the nicest clears I've ever sprayed through an airbrush.

My personal favorites are the Alclad clears, but they are lacquer and well not for everyone.

I've had some inconsistency with the Alclad satin/semi-gloss. But otherwise Alclad is my favourite as well.

I've gotten decent results from Alclad and, oddly enough, from Krylon out of the rattle can

Krylon is really good. I find with the Alclad semi the underlying paint finish really affects it. It can range from eggshell right up to a shiny lustre finish. Usually I just do a matte or gloss varnish. And then the semi. It's probably just my supply though.

   Is the Krylon acrylic or lacquer based  ?

  The RustOleum clears are acrylic   --   the primers and " enamels " are oil base .

They make acrylic, polyurethane, enamel, and lacquer topcoats.

But all the Krylon acrylics will have the word "acrylic" in the product name. Everything else is solvent based.
