Heating your Lacquer for phenominal results (kremlin in-line lacquer heater)

I thought I had said more on this subject of heating your coatings for better results and perhaps I have, but now time has gone by and the data has been buried somewhere over the years in some article somewhere in my Blog making it not all that useful.

Let me get to the point; when you raise th temperature of your coating, be it water based or solvent you are reducing the viscosity or thickness of the materials. With in a certain range of temperature for every 10 degrees warmer you make your lacquer (be it water based solvent or urethane)  you will make your product 10% thinner. The great aspect about that is that you are not reducing the volume of solids. 

If you thin a coating  50% you’ll have to put on twice the number of coats to achieve the same build. Here in America the labor is your most expensive commodity.  Now if you can raise the temperature of the materials 50 degrees you achieve that same amount if thinning but you would do it with out adding the solvents that will evaporate out and leaving your coating behind.

But that’s not all! In addition to the above the coatings you lay out will flow out better and dry faster. And you can do it with out the expence of Lacquer thinners which are getting expensive.

There are several things you can do to use this data, the easiest is to take your pails off the concrete floor and put them up on wood blocks if nothing else. I have had contractors wrap a heating blankets around their pails and warm their lacquer up that way.  I have even seen finishers put water based lacquers in the Micro wave and warm it up.

Intelligence needs to be used, especially when dealing with flammable materials. Making your materials warmer is the key but I wouldn’t go past the point of heating materials beyond warm to the touch. you can stick your finger in and its warm to the touch Body temperature is 98 degrees so I would say no more than about 104 degrees.  Obviously if your boil your materials you are going to be changing chemical properties. Again, some intelligence please.

With duel component materials you are going to be shortening the pot life. Gradients and testing are key here. I’m a big fan of pushing something to see where their fail point is but not on a customers cabinets, when you are at that point you should have all your procedures all figured out.

Ok, the basics covered,  here are two Video demo’s of Jody Toole using the Kremlin Air-assisted airless spray rig with the new Excite spray gun and the Kremlin materials heater. Jody is a professional finisher in the Southern California area, if you are interested in contacting him you can reach him through his blog at: http://jodytoole.wordpress.com/

In the first clip he is using the rig and in the second he is telling some of the benefits of the whole system. 

And here is the second video Jody describing some of the attributes of the Rig and his review :

For note: the Lacquer that we are applying here is the CIC Coatings Acrylic lacquer I have said so much about int he past.

 Annex Paint sells the Kremlin air assisted airless and all of  its sundries including the heater. If you are in the southern california area and would like a Demo please feel free to contact me.
