· Why grind pigments to make your own paint There are two basic reasons for doing so To break down agglomerates of pigment particles and to evenly disperse pigments in the paint binder Most artists are aware of the need to smoothly mix pigment with a binding medium but few are aware of how breaking agglomerations of pigment particles can also improve the color saturation of the paint Fewer
Grinding is done flat on a hard slab surface of glass or stone A Muller enables the artist to grind pigments to the color and consistency of their choice Mullers are used by all artist needing to grind their own pigments including fresco painters stain glass painters oil painters tempera painters and more Made for artists who want the control of mixing their own pigments A Muller is

As the pigment powder is broken down to individual particles by mechanical shear higher surface areas become exposed to the vehicle and larger amounts of additives are required to wet out newly formed surfaces Once dispersed the primary particles have a tendency to re agglomerate This process is called flocculation From a structural standpoint the flocculates are very similar to the agglomerates; nevertheless the interstitial spaces between the pigments
Excellent for multi use pigment grinds as grind defoamer and also in the let down of many flexo and gravure inks Hervorragend geeignet für vielseitig verwendbare Pigmentanreibungen als Mahlgutentschäumer und auch für den Einsatz im Auflackgut vieler Flexo und Tiefdruckfarben Very good pigment wetting and reduction of grind viscosity
· Arctic pigments are compatible in almost all solvent and aqueous coatings systems including polyesters acrylics and fluoropolymer systems To achieve full dispersion and optimum properties the pigments should be dispersed in a small media mill to at least a 7 Hegman Care must be taken not to over grind the pigment Additional grinding will
· On the whole I grinded some pigments for a half hour others for over an hour The test to a nice consistency is that the grinder when given a small push should glide smoothly by itself over the pigment When I was done I spooned the pigment into a small jar trying not to touch the sides of the glass I filled the jar with distilled water and covered tightly with a lid and in this state they can sit for a long time The pigment grinding
· For hard to grind pigments a premix followed by milling is required 2 Add liquid ingredients first 3 Add solids pigments slowly Allow time to fully wet pigment 4 May need to hold back some solvent/water to increase solids/viscosity Increase energy of mixing to help break pigment down to primary size 5 Pull samples during grind to track property color degree of grind visc as a
pigment dispersions with XM 2311 can be formulated at a high solids Picture 1 shows a pigment dispersion prepared according to Table 4 with a pigment to binder ratio of 1/1 using a Irgazin DPP BO red pigment and a grinding time of 16 hours on a pebble mill and let down with a PUD dispersion The same pigment dispersion diluted with water shows particles of about 1 micron dilution with a
· Your pigment grind should be the consistency of soft butter When you put it at a 45 degree angle it should not flow If it does you need to increase the pigment the next time you make it You should also be able to spread it with a spatula like it s butter if it spreads more like frosting you need to increase the liquid If it s more of a
Ideally you want a not too thick paste Too much water can make the pigment harder to grind but if spread out thinly the extra liquid evaporates out pretty fast 5 Grind round in small circles and every now and then scrape the pigment back together 6 When the pigment is smooth scrape it up and place it in your jar 7 Cover the pigment with more distilled water I would err on the side of too much water
