Many acrylic dispersions are suitable as binders for pigments. All polymer dispersions are mixtures / emulsions or dispersions of monomers and more or less long polymer chains in water.
Kremer Pigmente offers acrylic dispersions and polyurethane dispersions for various applications:
Dispersion K 52 (#75075)
Dispersion K 52 is a slightly milky, almost transparent acrylic dispersion with a very small particle diameter. It is excellently suited as a binder for XSL wood stains, for watercolor-like glazing techniques and for particularly matt paint layers. Due to the weak film formation, paint layers bonded with Dispersion K 52 are not as abrasion-resistant as those bonded with other acrylic dispersions. The thin-bodied dispersion has good penetration properties and is therefore also suitable for consolidating powdery paint layers, as a deep primer or for impregnating absorbent substrates.
Primal® WS 24E (#75250)
Primal® WS 24E is a plasticizer-free, low viscosity, slightly milky dispersion recommended as a deep penetrating acrylic solidifier for mortar or as a primer for acrylic painting on walls and wood. Dried films of Primal® WS 24E can be removed again with alkalis.
Dispersion K 19 Glanz (#75305)
Dispersion K 19 is the replacement for Dispersion K 6, which is no longer available. Dispersion K 19 Gloss forms a transparent, very hard, glossy film. The dried film does not stick. However, this dispersion is not very elastic and when applied in film thicknesses over 1 mm, the film is prone to breakage in case of strong bending. The Dispersion K 19 Gloss can be easily diluted with up to 4 parts water. It has been developed for waterborne clear coats and glazes on exterior wood windows. For exterior use, additional UV protection is required. For artistic purposes, the clear transparency, as well as the uniform gloss when applied undiluted, is particularly impressive. The addition of defoamer can lead to staining!
Dispersion K 19 Matt (#75355)
The dispersion K 19 Matt has comparable properties to the dispersion K 19 described above. A matting agent has been added to this dispersion, which settles during longer storage. Shake well before use!
Dispersion K 9 (#75367)
Dispersion K 9 is the replacement product for Primal® AC 33, which is no longer available and has similar properties. The pure acrylic dispersion is free of plasticizers, ammonia and formaldehyde and therefore comparatively low-odor. The unpigmented dispersion remains tacky for some time after application. It has a high pigment binding capacity, is more elastic than the other acrylic dispersions and is versatile. Due to its high elasticity, it is suitable for painting on flexible image carriers such as canvas or textiles. With highly diluted K 9, relatively matte or glazed color applications are possible, but the dispersion can also be thickened well and applied more pasty. It is also suitable for wall paints in combination with cellulose glue or with water glass or Syton X 30.
Dispersion K 500 (#75600)
Dispersion K 500 is a well pigmentable, plasticizer-free pure acrylic dispersion. The dispersion dries to an elastic, transparent film which may be slightly tacky at room temperature. It is suitable for the formulation of wash-resistant coatings for textiles and for the production of artists' acrylic paints. Furthermore, the dispersion can be used for the formulation of scrub-resistant coatings, as an aqueous primer for absorbent substrates, for resin-bonded plasters and as an additive to hydraulic-setting compounds.
Dispersion K 500 D (#75900)
Dispersion K 500 D is an acidic pure acrylic dispersion that dries clear, tear-resistant and flexible. It is mainly used for the formulation of adhesives and pressure sensitive adhesives. For use as a pigment binder, the pH value should be adjusted to 8-9, e.g. with ammonia.
Dispersion K 498 (#76000)
Dispersion K 498 is a particularly inexpensive pigment binder that dries clear, with medium gloss and medium hardness. The dispersion is plasticizer-free and has a wide range of uses: it is suitable as a binder for the production of acrylic paints, primers, weather-resistant facade paints, for synthetic resin plasters and fillers. Dispersion K 498 is suitable as an additive to silicate dispersions such as #77750 Potassium Water Glass and #31430 Ludox® PX 30.
Dispersion K 360 (#76101)
Dispersion K 360 is a pure acrylic dispersion especially for elastic, permanently post-adhesive coatings, for example for the production of self-adhesive coatings. It is the successor product to Plextol® D 360, which is no longer available, but with a different chemical composition and lower pH value.
Polyurethane Dispersion PU 52 (#76805)
The plasticizer-free polyester-polyurethane dispersion has good UV stability and is also suitable for exterior applications. It has good pigmentability, dries transparent, glossy and very elastic and is particularly suitable for coatings on flexible substrates such as paper or textiles. We do not recommend the addition of thickeners #76900 or #76910.
Polyurethane Dispersion 61 PC (#76806)
Polycarbonate Polyurethane Dispersion No. 61 PC is harder and more transparent than Dispersion PU 52, while the dried film remains highly elastic. Like Disperison PU 52, 61 PC is also plasticizer-free and suitable for exterior applications. The polyurethane dispersion cannot be thickened with thickeners #76900 or #76910.
