Hex Logic pads, de details (Engels).

[DAF-44]

Op het Engelse Detailingworld vond ik onderstaande informatie die voor (aspirant) Chemical Guys - Hex Logic pad gebruikers welicht interessant kan zijn.

Misschien kun je er een sticky van maken Wesley?


Following a popular request at machine polishing classes, this post gives my opinions on the Hexlogic pads, the order of cut and typical uses for them


Red - Glazing / Waxing / Finishing (Open Cell Foam)
Use with non-abrasive glazes for example, such as EZ Creme Glaze or Lime Prime Lite for cleansing, or to apply liquid or solid waxes.

Black - Finishing (Closed Cell Foam)
Use with finishing polishes for refinement purposes or light correction on softer paint types - typically with Menzerna PO85RD Final Finish, or PO106FA Super Finish or Meguiars #205 etc...

Blue - Light Polishing (Open Cell Foam)
Use with finishing polishes for finishing or light correction work, or slightly more abrasive polishes for light to moderate correction work - typical polishes would be Menzerna Final/Super Finish, 203S Power Finish, Meguiars #205, 3M Ultrafina or Extra Fine Cut.

White - Polishing (Closed Cell Foam)
The workhorse pad of the range - for polishing duties, anything from light correction to moderate/heavy correction depending on the paint. Use with anything from Menzerna PO106FA Super Finish to PO85RD3.02 Intensive Polish, Meguiars #205 or #105, 3M Extra Fine Cut, Ultrafina etc.

Green - Heavy Polishing (Open Cell Foam)
Bridging the gap between general polishing and cutting/compounding where an intermediate step is required... use for more severe correction than the white pad, with products such as PO203S Super Finish, Meguiars #205/105, Intensive Polish etc.

Orange - Cutting (Closed Cell Foam)
A heavy correction pad, typical products would be Intensive Polish for heavy correction, or for more severe work products like Power Gloss, Fast Gloss, Fast Cut Plus, #205(SMAT finishing polish can cut well on this pad!), #105 etc.

Yellow - Compounding (Open Cell Foam)
Top of the tree cutting wise, this is the heavy duty pad for use with products such as Fast Cut Plus, Power Gloss, #105 etc for severe defect correction.


This is just a basic summary to give a general idea - expriment and try the pads with different products and see what you can achieve but as a starter for ten, this is a general guide to the pad choices.

Onderstaand een (wederom Engels) stuk waarin e.e.a. uit de doeken wordt gedaan over open en gesloten celstructuren.

Reticulated Polyester Foam which is basically an open cell structure. The Prepolymer Foam pads are the opposite and are closed cell. The reticulated polyester foams cutting performance varies with pore size, (ppi, pores per inch). Their open-cell construction allows for fluids to permeate the pad to a greater degree than closed-cell materials, such as prepolymer foams, and their lower tensile strength allows them to "mould" around contours more easily. The prepolymer foams work by the abrasion generated by their density, rigidity and tensile strength. The foam keeps polishing compound on the work surface longer, producing varying degrees of cut according to these three properties and the force applied.

The practical difference between open and closed cell foam is the ability of the open cell to assist in the drying process while buffing. It means that air can pass though the open cells, this feature helps the polish or compound dry as opposed to closed cell which inhibits or delays drying. It is essential that whatever polish you are using has a drying and breakdown point, otherwise it will not perform to its highest potential. Closed cell foam has a tendency to push the polish around for a longer time, so from a practical standpoint it takes up more time and requires more work for the user.

During our test we noted that the Prepolymer foam clogged more and sometimes we experienced some ‘grabbing’ on the panel, therefore we needed to clean the pad more often which again added to the overall time it took to polish the cars on our tests. Also in my experience with polishing I have noticed that when first starting the process with a prepolymer foam pad it grabs more than a reticulated polyester pad, I stress, this may not be fact for all detailers as it could be more with my technique than anything else but there was a noticeable difference between the two foam types.

Zo te lezen op DW worden deze erg veel gebruikt in UK en dat verbaast me niets.

Net zoals in Zuid Limburg

Juist!

Wat is trouwens het verschil tussen de open en gesloten celstructuur?

Interessante stukjes, bedankt voor het plaatsen!

Schijnbaar zit er toch meer achter zo'n simpel stukje schuim.

een leuk stukje om telezen.
