Kremlin Rexson PU3000 Showcased at IWF 2012 Booth 1407

Kremlin Rexson PU3000

EXEL North America, Inc. is pleased to introduce the New Kremlin Rexson PU3000 at the IWF 2012 tradeshow August 22-25, 2012 in Atlanta, GA. 

The Kremlin Rexson PU3000 incorporates a unique “Plug and Play” concept for mixing two component paints.   

The PU3000 delivers:

Ø  Pulsation free performance

Ø  Improved quality of mixing & application

Ø  Accurate, reliable mixing & controlled fluid delivery

 If you currently hot pot (hand mix) and have infrequent color changes, this is the perfect machine for you!  

On average, the PU3000 will save or add about 50 minutes of production time each day. The PU3000 will reduce material waste and facilitate faster clean-up, which significantly lowers operational costs.

Ø  Increase production time

Ø  Reduce material waste

Ø  Faster clean-up

We also offer a PU3000PH unit specifically designed for acid catalyzed materials.

For more information, please come by our booth 1407 at IWF in just a couple of weeks.  We look forward to seeing you!

How to do an Effective Electrostatic Demo

I found this oldie but goodie article from the archives on how to do electrostatic demonstrations.  This is one of those pieces of advice that still holds true today and never goes out of style….. I don’t know who wrote it.  But I do know they work for us!

“….While doing electrostatic demos in the past, I frequently asked the customer how my competitor did during his demo. I usually heard very bad comments like:

• His equipment didn’t work!

• Black stuff came out of his pump!

• He didn’t have the right gun!

• His nozzle was wrong!

In general, my competitor just wasn’t prepared! Was I glad that wasn’t me because I would never do a demo that unprepared! Now it was my opportunity to show the customer my “stuff”. I started to carry my demo equipment into the plant (three trips to my car).

Assembly took me almost 30 minutes and of course, I was missing an air hose. I asked the customer for quick disconnect fitting and another 15 minutes went by. The real problem came when I asked the customer for a 5 gallon bucket (clean, of course). He found a bucket that was currently used as a trash can and made an attempt to scrape it clean. Another half hour. Obviously, the customer was not impressed, as we were not spraying paint yet.

Finally 1½ hours later, we have the paint in the system but for some reason it s not wrapping and I find out that the black paint has carbon in it and it is shorting out the electrostatics. On the way back to the office, I am very discouraged and frustrated. Then it dawns on me – “I am my competitor”. I just made the same mistakes that I was laughing at him for doing. I thought could never be that stupid. Boy, it was a long ride back to the office.

During this drive, I started to think. I don’t have to worry about my competition. “I am my competition.” I lost this sale by myself. It was totally my fault as the term “the easiest way to lose a sale is to do a demo” entered my mind.

Then I started to get mad at myself. How could I be so stupid? What can I do so this never happens again? My brain went into the “deep thought” process. “Yes, I do believe I can plan so that this doesn’t happen again and my close ratio on sales will certainly go up as I can then be in control of the situation.”

This is what I decided I must do:

1. All equipment must be cart mounted.

2. All equipment must be assembled – all hoses, fittings, etc. This eliminates any chance of leaving things at the shop.

I must bring with me:

  • Five Gallon bucket with line
  • One gallon cans (new)
  • Rags
  • Solvent for cleaning (one gallon)
  • Zahn cup or Afnor 4 cur
  • Stop Watch
  • Quick disconnect fittings (6 stems will cover most customers)
  • Cart must have an air blow gun (non safety) or a ball valve for quick easy tip cleaning
  • Solvent for conductivity adjustment
  • Paint Meter
  • Anything else?

Yes, this sounds like I have everything and I’ll really be organized and prepared, but what about that “black” hot paint?

How Does an Electrostatic Paint Sprayer Work?

Ever rub a balloon against yourself and make it stick to a wall or other object? That is the basic idea of how an electrostatic paint sprayer works. The rubbing of the balloon causes it to obtain more free electrons, which makes a negative charge. The negatively charged balloon now will stick to neutral or positive objects.  Ken Eyestone is our training manager at Exel North America, Inc.  And according to him, electrostatic paint sprayers are the way to go to save paint, money and the environment.

Paint Sprayer

  • At the tip of the paint sprayer is a small electrode, which creates high voltage electricity. As the paint particles travel at a slow speed through this corona of electricity, they become negatively charged.

Paint Surface

  • The paint surface is the grounded, positively charged surface, which has a magnetic attraction to the negatively charged paint. As you spray the paint, the paint overspray may initially travel off in a different direction, but will turn back to the positively charged object and stick to it. The paint will stick to any surface that is conductive. Metal definitely. Wood has water in it, and the wetter the wood, the greater the positive charge. Surfaces that include plastic, stucco and wood that are old and very dry will need a thin coat of conductive adhesive promoter applied before painting.

Paint

  • Electrostatic paint sprayers work well with an oil- or water-based paint. However, water has a stronger positive charge than oil. The paint needs to be able to hold a charge, but not be too conductive. Solvents can be added to paints to make them perfectly charged. Contact the manufacturer of the paint to see what, if anything needs to be added to the paint. The size and velocity of the paint particles is also important. The smaller the particle mass, the greater the attraction. The slower the particle, the greater the effect of the paint charge.

Benefits

  • The benefit of using an electrostatic paint sprayer is in the saving of paint. Expect to use 25 percent to 50 percent less paint. In a big job, that is a lot of paint and money saved. There is less waste which is good for the environment. There is very little overspray to clean, and the paint coverage also has a very nice, smooth look.

Drawbacks

  • If you have sharp edges, the paint will go on much thinker. The particles of paint are very attracted to corners and sharp edges. Where you have an inside corner, the paint goes on much thinner, if at all. This is called the Faraday Cage Effect. The solution to this problem is when spraying into a corner, the painter paints with electrostatics that are turned off for that part.

Warning

  • If the surface to be painted is not grounded, the charged paint particles will search for the nearest ground. This will in all likelihood be the painter!
