Conductive surface

[Guest]

Anybody know of a spray solution that provides a conductive surface. For wood

Re: Conductive surface

I had tried various solutions,all with the same results,outgassing from the steam.I have better luck just preheating and hotflocking several coats.

Re: Conductive surface

Thanks Polert. Call Ms Perry and let me know the outcome of that experiment. I ain't got the time for that BS

Use liquid to powder and a HVLP gun.

LIQUID CONDUCTORSPerry, Jean M. Oakton Elementary School Evanston, IL 1-708-492-7981 Objectives
1. Students will construct a circuit tester.
2. Students will predict what liquids are electrical conductors.
3. Students will test and identify liquid electrical conductors
and non-conductors.

Apparatus Needed (for each group of four students)

*4 D batteries vinegar
*4 battery holders salt
*1 bulb holder ethyl alcohol
*8 brass electrical clips sugar
*2 Fahnestock clips baking soda
*l l 1/2V miniature bulb distilled water
#20 bare copper wire as needed tap water
large covered containers lemon juice
markers safety goggles
labels paper towels
plastic tumblers activity sheet

Recommended Strategy

This activity should follow the study of "series" and "parallel" circuits; the
teaching of how to construct a circuit tester; and the testing of solids for their
ability to conduct electricity.

Advance Preparation:
-Organize materials in a shoe box or tray for each group of three to four students.
-Test the batteries and bulbs to make sure they work. Have replacements available.
-Make a circuit tester for liquids and have it on display for students to use as a
model for making their circuit tester. (Circuit tester should be a series circuit
made of four D batteries with the Fahnestock clips as electrodes.)
-Prepare solutions of salt, vinegar, baking soda, sugar, lemon juice, and ethyl
alcohol in distilled water. Use your own judgment as to the proportions; the
liquids need only be strong enough to light the bulb in the tester. Store the
solutions in clearly labeled, covered containers.
-Prepare an activity sheet for recording observations. Activity sheet should include
columns for recording the names of liquids tested, student predictions, and
observations.

Doing the Activity:

l. Students write the names of liquids to test in chart (activity sheet).
2. Students predict if the liquids will or will not conduct electricity. Prediction
is recorded.
3. Circuit tester is made using teacher's tester as model.
4. Each tumbler is labeled with the name of one liquid.
5. Students are reminded to WEAR SAFETY GOGGLES. At least 3 cm of one liquid is
poured into the correct tumbler. The clips of the tester are put into each
tumbler at equal depth and equal distance apart. Observations are recorded.
6. Testing liquids will need some guidance from the teacher. For best results, the
flat sides of the clips should face each other. The liquids should not be mixed,
and the clips should be cleaned between tests.
7. Discuss:
a. What liquids will allow the bulb to light?
b. What liquids will not allow the bulb to light?
c. Does the bulb glow with the same brightness with each liquid?
d. Are there any changes in the clips when you are testing?
e. Did you notice anything happening in the liquid when you were testing?
8. Record conclusions on overhead or chalkboard.

Optional Activities:
l. Have the students repeat the activity using liquids brought from home such as
coffee, liquid soap, orange juice. DO NOT USE CAUSTIC, CORROSIVE, OR POISONOUS
LIQUIDS.
2. Interested students may advance into the study of acids, bases, and salts.
3. Challenge students to design another type of conductivity tester.

Tap water?
ethyl alcohol?
two options that may have good results with PC.

I'm not tracking... I don't see how the experiment above is relevant to powder coating. I can think of a lot of conductive liquid coatings but finding one that will attract the powder and still leave a quality finish on the non conductive substrate is the problem here. I don't think applying lemon juice or coffee to the part is going to help him achieve his goal.

so wait...could i coat a potato battery?

No, you use use the patato battery to power your gun.

Re: Conductive surface

Liquid tin.... Thats how they make mirrors, Apply hot/liquid tin to a sheet of glass. The tin is self leveling creating a flat reflection.

Impractical though....

Re: Conductive surface

now polert feel free to smack me upside the head if I'm wrong but....

I think what polerts point is, is TRY THINGS! I have some totally stupid things sitting out in my shop that you would look at and wonder what the heck was this guy thinking. I bet if you walked into Thomas Edison's shop, he had some pretty dumb looking things he was trying out to get that damn light bulb to work. But once and a while, shit works.

Creativity ALWAYS looks like insanity from the outside. Coffee and lemon juice sound like really dumb ideas...but did you try it? I was of course completely joking about the potato battery thing...but there is current there...why? (see polerts experiment for the answers maybe!) if you can electrify a potato...there's got to be an electrical field there. What about MAKING a field around a thing? magnets are cheep...electromagnets are strong...ideas ideas ideas learn to love alllllll the ideas and filter the ones that wont work for your problem. No idea is a bad one, its just that a Philips screwdriver will not work on a slotted screw.

Learning things used to be really hard what with books and all. Now we have google and anyone in the world can know anything. But that still doesn't mean you don't sometimes have to work for the answer you need.

Re: Conductive surface

It is very possible, I would think the "conductive liquid coating" would need to be some form of paint that has conductive properties. When I coat wood I use a liquid filler/primer for the base. The wood has pores that need to be filled. I then sand the primer to give me a nice smooth finish. Then I place the part in the oven foe a few minutes and hot flock the powder on the wood. I have done this on some rifle stocks and fishing lures. The finished product is a smooth surface that looks like it was applied over metal. I will see if I can round up some pictures of the results.

There are a lot of variables in the process of coating wood. The problem is the wood itself as every type of wood has different properties.

Re: Conductive surface

Ty1854, your on the right track and thanks for your help. So you have powdercoated some crankbaits I would like to see some pictures of that. I was reading up on powder coating wood, it was mentioned that some powder coaters use a spray solution for a conductive surface. I thought somebody here would know or has used it. Which was William Smith, I think he knows what I was refering to.

Hey ALpowder

Try Caswell Plating they have a spray might work.

What type of liquid filler/primer do you use?
