Common complaints:

Dust and dirt inclusions

Halo’s Dark edges

Blending issues

Colour matching issues

The “overall cause is static electricity”

Static is the invisible enemy of the perfect paint finish!

Rubbing two things together or bringing repetetly into contact is enough to create triboelelectricity,

Stored energy

Triboelelectricity

What creates it:Bringing different

materials into

contact

Named as:


-

1. Plastic (black) and tackrack ( gray) normally have no electric charge.

2. Put them in contact and the plastic attracts electrons from the

tackcrack.

3. Separate them and the electrons remain on the plastic, making it

positively charged.

4. Rubbing the two substances together increases the contact between

them and makes the that electrons will migrate from the tackrack to

the plastic. Static build-up!

Many everyday processes within a bodyshop can cause static build-up, sanding, panel wiping, tacking, blowing off, masking and even the application of materials.

The final preparation process of tacking is one of the highest generators of static electricity.

All these procedures incorporate some type of contact and separation with the panel, whether it is physical contact or air contact.

Dry areas

What reduces static build-up

Humidity


Differences in positive and negative static charge on a surface will prevent the paint film from applying evenly.

A grill is a perfect example of where static will not allow perfect paint flow and will often prevent coverage in all the corners of the grill.


Metallic particles in paint react to static charge in the same way iron filings would behave when a magnet is placed underneath. The higher the charge the more upright the metallic will be forced to sit, in turn distorting the levels of light reflected from those particles, in fact any area which shows an inconsistency between light and dark can be caused by metallics being distorted by static.

Result: dark edges, patchiness, halo’s

all substrates on a vehicle should have zero static charge before painting to bring a uniformity

Panels that are statically charged form an electromagnetic field and, as the word magnetic indicates, attract any airborne particles from the surrounding area,.

The smallest particles of dust and dirt within a job can incur costly

rework, through additional labour and paint costs.

Static build-up, neutralised, dust and dirt in the atmosphere is no longer attracted to the panel


The way to remove static effectively throughout the painting process is to use ionised air. As the static forms in positive and negative charge, the positive and negative ions produced from the Stat-Gun neutralise the charge (positive neutralises negative & vice versa).


This is achieved by introducing the Stat-Gun as the final stage of the preparation process just prior to spraying.

The Stat-Gun uses a microprocessor to generate high voltage transferred through tungsten emitters, which in turn generate positive and negative ions.

Air flow is an important part of the process allowing the ions generated to travel quickly and distribute evenly over the charged area. Air movement also aids removal of contaminates previously bonded by static charge.
