intercoat clear

what is the purpose of this and whats it do? I was at my paint supply house picking out the color for my truck, and i wanted to add just a touch of purple pearl, and the guy behind the counter said I would need intercoat clear, I dint want to ask him what the heck he was talking about, since there was a long line there, I also looked it up and only found house of kolor that makes it, does any one else make it? but if anyone could shed some light on this for me

Intercoat clear is sometimes called binder clear or mixing clear..it is used with candies and pearls as a carrier for those componets of a paint job..Sometimes base colors are mixed in an intercoat clear as well..

The basic overview is that first one primes and seals the car..then a solid base coat is shot..then we follow with the intercoat clear with the candy or pearl in it..then we clear coat the entire thing..

As far as specific requirements one needs to conatact his jobber or Paint rep for specifics related to the specific line of paint one is using..

Intercoat is suppose to give less film build and allow you to
protect your graphics so you can go on to the next color.
It's also suppose to dry quicker so you can retape faster.
I personnaly don't like it and just use a thinned clear instead.
I do have to wait longer between tape ups for graphics.

It is supposed to spray easily like a basecoat, but it doesn't have any iso's or hardener...

It is all of above but more simply a "colorless basecoat". Most color formulas that match original pearls for instance, are simply this "colorless basecoat" with some pearl added to it. It is applied over a "colored basecoat" and then the whole shooting match is cleared with a urethane, hardened, clear.

I first saw it back a number of years ago (before there were many pearl colors on new cars) in the DuPont tech book as a remidy for protecting a blend. You took this "binder clear" off the mixing bank that is used in formulas to create the millions of colors we have, reduced it 1:1 with the basecoat reducer (DuPont calls it "Basemaker") just as you would any other basecoat and spray it over the blend area. You then cleared the whole panel with your urethane topcoat clear.

A short while later many other companies came out with a whole seperate product (though basically the same) in a can called "Innercoat clear".

Each brand name has a different approach/product for this application so it's best to ask specifically depending on product.
Intercoat is basically a clear "transport liquid" for custom work or a color reducer for blending.

HOK has a specific product called SG-100 that is used for many different purposes in their line. Mixing kandy KK Koncentrait for small kandy jobs,thinning of any of there product line for various reasons,Pearl coats,Flake coats,etc.
Dupont has their binder,155, which is a colorless base paint in the Nason line.
I use this for doing kandy on small projects or as a color reducer for making weak,transparent colors for air brush work,Pearl coats,etc.
Dupont also has a blending clear,175, which is NOT made for this application. It's used for blending into repairs of existing paint and stays "wet" longer to melt into the existing job.Not that you can't apply color to it but it's not very user friendly for a stand alone coat.

Intercoat should be thought of as another base coat for whatever the reason.
Effect,color,protection,build.

If your supplier carries HOK products, Pick up one of their Tech Manuals. It will explain most ANY paint product in detail and is a handy reference book.Sure there are differences between them and the other lines,but the principals are the same.

HOK intercoat clear has no UV protector in it so it must top coated. I use it to mix my dry pearls and to do tape outs .. Its nice because I like to get away from Iso's as much as possible .. just a 1:1 with reducer. The intercoat is much thinner than a 2k dries faster And must be used if u r using Marbilizer from HOK and topcoating wuth a Uro clear or the clear will delaminate..

You can certainly do that. Or (in my opinion) better yet, shoot on a coat of your catylized clear to protect your base coat and then do your pearl/clear mix. That way you have the option of removing your pearl coat if say your decide you used too much pearl and not mess up your base coat. I use inner coat clear all the time I have used the HOK, X-otic and Matrix brands and they are all the same near as I can tell. I mainly use it when Im doing airbrush work, overlapping ghost flames etc; That way I can lock down my artwork, graphics etc come back later and scuff and do the next layer. All I use it for is a protective barrier so I can scuff it without damaging my graphics and then shoot my final catylized clear coats. You can also (as previously mentioned) use inner coat clear as a carier for candy concentrates or pearl. I wouldn't reccommend using it as a carrier for flake. AL
