The encreased demand for high quality and fast drying of varnishes, paints and other coatings has called for tinting systems, such as MIXOL® to expand their assortment of oxide shades. With our MIXOL®-Oxide tints our product range offers a number of inorganic pigments of outstanding quality and fastness that meet even the highest demands! The MIXOL® product range has always included oxide tints, although the variety of shades was limited. Now 15 magnificent MIXOL®-Oxide-Types are available! All MIXOL®-Oxide tints are inorganic mineral pigments, being the oxide of various metals. These hight quality products are light fast, weather proof and won’t fade. MIXOL®-Oxide tints are most important for outdoor application and when working with high quality, complex materials. For best results, use MIXOL®-Oxide-Tints exclusively, if you work with one of the following materials:
MIXOL® Oxide Tints: WHEN and WHY are they used?
The increased demand for high quality and fast drying of varnishes, paints and other coatings, has also called for extremely high standards to be met by tinting systems such as MIXOL®.
With our MIXOL® Oxide Tints our product range offers a number of inorganic pigments of outstanding quality and fastness that meet even the highest demands!
What are the advantages of MIXOL® Oxide Tints?
All MIXOL® Oxide Tints are inorganic mineral pigments, being the oxides of various metals. Thus they are light fast, weather proof and won’t change their colour for years or show any fading. These conditions are all essential for outdoor applications.
When tinting silicate paints which are commonly used for outdoor application MIXOL® Oxide Tints have always been referred to. And indeed – this is an excellent usage for MIXOL® Oxide Types or any mixtures of these.
Problems arising during the tinting of silicate paints are due to their extremely high alkalinity in the wet state. MIXOL® tinting pastes which are not of the “oxide types" may cause problems in silicate paints. There are several reasons for such problems.
In contrast to varnishes and dispersions, silicate paints do not produce a closed film. The stability of silicate coatings is due to their “silicification". This means the coat of paint remains “open-cell", “breathable" or “water vapour permeable". However, it also means that the pigments included in the coating are very much exposed to any aggressive environmental conditions like light and weather. Only selected high-quality pigments like the MIXOL® Oxide Tints are resistant to this environmental load.
Moreover depending on the quantity added, the wetting agents necessary in the standard (organic) MIXOL® types may seriously disturb the “silicification" of the silicate paints. Water-spotting and washed out pigments at the surface might be possible consequences!
In MIXOL® Oxide Tints different wetting agents are used which do not
affect the “silicification" or the quality of this coating!
When tinting other mineral building materials such as lime, concrete, cement etc., alkali resistant pigments are essential. Because of their alkali stability MIXOL® Oxide Tints are the best choice for tinting of these materials (with the exception of No. 30 Oxide-Brilliant Yellow which, when used in high alkalinity materials, nevertheless shows strong light fastness and weather resistance!). The maximum addition of 3–5 % of MIXOL® products should not be exceeded. We recommend using a masterbatch by tinting a smaller amount of material and then stirring this into the total compound to be tinted.
Silicone resin paints have a high water vapour permeability! In this respect they are almost as good as silicate paints but without having their disadvantageous high water absorption and their high alkalinity. However, they do have a comparable porosity.
As silicone resin paints are usually applied over mineral grounds which have not been sealed with an appropriate primer in order to keep them water vapour permeable, the alkalinity of the ground may adversely affect the pigment.
Therefore, only MIXOL® Oxide Tints (inorganic pigments) can be
recommended without restriction for silicone resin paints!
Polymer resin based insulating varnishes and sealers containing solvents can only be tinted by MIXOL® Oxide Tints. A maximum addition of 5 % should not be exceeded. Cationic aqueous insulating varnishes and sealers can largely be tinted with a MIXOL® Oxide Tint addition of up to 1 % (approx.), or even up to 5 % (approx.) using MIXOL® Oxide Brilliant Tints Nos. 29–32. We recommend testing the compatibility of MIXOL® Oxide Tints with the material used before starting the tinting process.
After tinting the material should be immediately processed as, due to the particular ion technology of insulating varnishes and sealers, a chemical action may occur which can result in immediate or delayed thickening of the material.
Another advantage of the MIXOL® Oxide Tints is that they can normally be used without any problems in varnishes which are low in, or free from aromatic compounds or in other paints that occasionally cause tinting problems
(see section of “insulating varnishes and sealers”).
In silicate paints and other mineral building materials, in silicone resin coatings, in varnishes which are low in or free from aromatic compounds and in insulating varnishes, sealers as well as in exterior paints containing solvents
MIXOL® is a binder-free multi-purpose tinting paste – not a ready-made paint! – Shake thoroughly before and close firmly after use so MIXOL® will not dry out or form lumps or skin. MIXOL® is highly resistant to frost and heat. After freezing it needs only to be thawed at room temperature. Then shake thoroughly and it is ready for use again. Depending on the paint concerned, MIXOL® may be added up to a maximum of 10 % by weight. But considering that it is highly concentrated, you can obtain best results by adding a minimum of MIXOL® (please see the percentage additions in the MIXOL®colour card). The maximum additions are: 10 % to latex and/or emulsion paints, 5–8 % to paints, lacquers, varnishes, high-solids, 6 % to acrylic paints, 3–5 % to transparent and/or clear lacquers, transparent paints, glazes, wood stains, waxes etc., 3 % for silicate and silicone paints and/or coatings. Use only MIXOL® oxide tints in varnishes low in or free from aromatic compounds or in paints containing silicate silicone resin! (Red cap = oxide type!) MIXOL® tints which are no “LW oxide types” are unsuitable or only suitable to a limited extent for colouring latex emulsions containing solvents, or for colouring polyester resin finishes, single or two component synthetic resin paints. In case of tinting lacquers sometimes MIXOL® cannot be mixed easily by hand, therefore use a stirring apparatus, if possible, to get optimal results and to avoid a rub-out effect. It is also important to test results after stirring! Always test for compatibility by means of a “rub-test”. Brush on some of the tinted paint and immediately rub hard with your finger. If it turns a darker shade, the material is either incompatible with MIXOL® or the concentrate has not been properly stirred in. Stir well again and repeat test. Add MIXOL® first and only then add the thinner if required! MIXOL® tints No. 6, 7, 10 and 18 are for indoor application only! When a yellow or red are required for external applications, use True Yellow No. 26, True Red No. 27 and Oxide Brilliant Yellow No. 30 instead of the internal quality No. 7 Canary Yellow and No. 10 Red. For internal application (e. g. on new wood and other surfaces) we also offer a multi-purpose concentrate White No. 25, which should be added to colourless coatings and/or transparent paints, glazes etc. to create a pickling effect. Attention: Please read the MIXOL® leaflets as well as the instructions and technical information in this colour chart and on the labels and be aware of the two different terms:
LW types and/or LW oxide types: Fast to light and weatherproof, for indoor and outdoor application.
L types: For indoor application only.
The percentages listed on this colour card are quantities of MIXOL to be added by weight.
Slight deviations of the colours on this colour card are due to screen view.
NB: White paints containing different levels of titanium dioxide will tint differently using the same quantity of MIXOL.
