I’d like to prove with this little observation that the AS claims of FK are true and the product(s) are working as they should – and not how they ought to; based on some members’ imaginations/opinions/beliefs/perceptions.
So, attention non-believers: I don’t wanna confuse you with facts, but read on and see the pics.

Anti-static compositions for molds, molded parts and painted surfaces
Abstract
Wax-based composition for protecting and polishing paint, plastic and metal surfaces, or as a mold release, to remain free of CLINGING dust, comprising a first hydrocarbon wax having a relatively higher HLB (hydrophilic lipophlilic balance – Bence) value, a second hydrocarbon wax having a relatively lower HLB value, the first and second waxes being combined into a wax blend having an intermediate HLB value based on the proportions of each wax, a solvent for the blend, the solvent having a given HLB value, the HLB value of the wax-solvent mixture being predetermined by the wax blend HLB value and the concentration and HLB value of the solvent, and a small but effective amount of a quaternary compound having an anti-static persistence at the predetermined HLB value to maintain the surfaces protected, polished and free of CLINGING dust.
Description
TECHNICAL FIELD
This invention relates to anti-static compositions for plastic parts molds, for molded parts and for painted surfaces, especially automotive painted surfaces. More particularly, the invention is concerned with modifications of wax, sealer and mold release compositions to permit effective incorporation of anti-static agents, while retaining their protectiveness, durability, polishability and gloss.
BACKGROUND
Wax and sealer compositions find wide use in protecting and polishing metal, painted and plastic surfaces, and as release agents in molding and lay-up operations. Natural and synthetic waxes are blended with solvent systems and applied to the surface to be protected. Often the applied wax is buffed to a high gloss. Also the surface to which a wax release agent is applied may have been preliminarily buffed before waxing or sealing to ensure the smoothest possible surface.
BUFFING AND POLISHING ENGENDER IN THE WAX OR SEALER A STATIC CHARGE WHICH ATTRACTS DUST AND OTHER AIRBORNE PARTICLES TO THE SURFACE ADVERSELY AFFECTING APPEARANCE, AND, IN THE CASE OF MOLD RELEASE AGENTS, BRINGING POTENTIAL SURFACE DEFECTS INTO THE MOLD.
SUMMARY OF THE INVENTION
THE USE OF VARIOUS ANTI-STATIC AGENTS IN WAXES (WHICH TERM, UNLESS OTHERWISE INDICATED, IS USED HEREIN TO INCLUDED WAXES PER SE, SEALERS, AND MOLD RELEASE AGENTS BASED ON WAXES), IS BROADLY KNOWN. PRIOR WORKERS, HOWEVER, HAVE FAILED TO RECOGNIZE THE CRITICALITY OF TAILORING THE WAX COMPOSITION TO CREATE THE OPTIMUM ENVIRONMENT FOR THE ANTI-STATIC AGENT WITH THE RESULT THAT ANTI-STATIC EFFECTS ARE NOT REALIZED DESPITE THE INCLUSION OF ANTI-STATIC AGENTS IN THE FORMULATION.
It is an object therefore of the present invention to provide improved wax compositions which are persistently anti-static when applied onto a painted, plastic or metal surfaces as protective polishes or as a mold release...
...It is another object to provide surface waxes, polishes, sealing agents and mold release compositions in which a blend of waxes having as a blend a predetermined HLB number is combined with solvent having an HLB number selected with reference to the HLB number of the wax blend to bring the HLB number of the solvent wax blend mixture to a value compatible with persistence of the anti-static agent in the mixture.
These objects and other objects to become apparent hereinafter are realized in accordance with the invention in a wax-based composition for protecting and polishing paint, plastic and metal surfaces TO REMAIN FREE OF CLINGING DUST...
DETAILED DESCRIPTION
...IT HAS BEEN FOUND THAT THE INVENTION COMPOSITIONS ARE NOT DUST REPELLANT, OR SO CHARGED THAT DUST DOES NOT ACCUMULATE, BUT RATHER, THE SURFACE, BE IT A PLASTIC SURFACE, A MARINE PAINT SURFACE, A CAR FINISH OR, IN THE MOLD RELEASE EMBODIMENTS OF THE INVENTION, THE HIGHLY POLISHED INTERIOR SURFACE OF A MOLD, IS NON-RETENTIVE TO DUST AND DIRT. THERE IS NO CLING OF DUST OR DIRT TO THE SURFACE, SO THAT UPON LIGHT BRUSHING OR EVEN BLOWING THE DUST OR DIRT LEAVES THE SURFACE...
EXAMPLE 1
An automotive paste wax...
...product was evaluated by applying to steel panels coated with automotive paint and rubbing until a high gloss was obtained. The panels were exposed in an open, unpaved area during daylight hours and periodically inspected for accumulation of dust. IN ALL CASES DUST ACCUMULATED ACROSS THE PANELS SURFACES. Periodically, the dust was brushed off the panels with a soft, untreated brush; there was no remainder of dust on the panels, INDICATIVE OF THE PANEL SURFACE HAVING NO ELECTROSTATIC ATTRACTIVENESS FOR THE DUST. These results are noted for multiple day exposures until the test is discontinued.
In a control, the above formulation is repeated but with the use of 100% of the higher HLB value wax, so that the HLB value of the wax portion was 15, and that of the solvent 17. A DECREASE IN THE NON-ATTRACTION OF THE PANEL SURFACES FOR DUST WAS NOTED AFTER A SECOND DAY OF EXPOSURE, WITH THE ACCUMULATED DUST BEING INCREASINGLY DIFFICULT TO REMOVE BY SIMPLE BRUSHING. In a second control, THIS SAME LACK OF PERSISTENCE IN NONRETENTION OF DUST IS NOTED when 100% of the lower HLB value wax (HLB=8) is used in the example procedure.
It was concluded that the adjustment of the HLB value to one at which the quaternary amine could persist added greatly to the effectiveness of the composition as a wax and as a dust nonretentive...
Now, the pics. FK 425 is applied on the left half of a Panasonic TX-29S PS2/B’s screen; the other half is untouched. After a week (Friday-Friday), there was a noticeable difference in dust accumulation. There is dust on both sides, but CONSIDERABLY LESS with Finish Kare’s 425 QD. Enjoy:
