There are many reasons why Tylose® is an important component in water based paints for ceilings, walls and facades.
Application of paint should be smooth and easy, whilst spatter must be kept to a minimum. To achieve these attributes only a small amount of Tylose is necessary. Depending on the system being used, a concentration of 0.2 % - 0.5 % is typically required. The choice of Tylose types depends on the application and requirements. The most commonly used Tylose types in coating materials are Tylose HS and Tylose H.
Filter applications by:
Interior paints
Interior emulsion paints, often just referred to as interior paints, belong to the group of most commonly used coatings. Apart from their decorative and protective properties, they facilitate the cleaning of interior walls and ceilings. For interior paints with low spattering the use of hydrophobic modified Tylose is recommended.
Exterior paints are used for decorative design as well as for protecting surfaces from the destructive influences of weathering. Suitable substrates include renders (mineral and polymer based), concrete, brickwork and other coatings.
Silicone resin paints are predominantly used for exterior application. They are a combination of a silicone resin emulsion and a polymer dispersion. The formulation benefits from the combination of good pigment-binding power of the polymer emulsion with the excellent water-repellent properties of the silicone resin.
Full colour paints or tinters are non-white emulsion paints. They are used in concentrated form for colour coatings (full colour paints) or mixed with interior or exterior paints before use (tinters). Tinters are compatible with a large number of emulsion paints.
Silicate paints are based on silicate solutions. After application, silification occurs and a non-continuous film is formed on the substrate. This leads to an excellent water vapour permeability. Silicate paints are often used for renovation as well as for the coating of older building fabrics.
Limewash paints are aqueous slurries of slaked lime (lime hydrate) with added pigment. The chemical reaction of the lime hydrate with atmospheric carbon dioxide results in a non-film forming coating which is not resistant to acidic gases.
Often, they have poor hiding power and several coatings must be applied.
Distempers are among the oldest paints for interior use. They are available as powders and paste-like form. Apart from regulating the consistency of distempers, Tylose® also acts as binder. Distempers are not water resistant and cannot be painted over. In today’s paint industry they are of minor importance.
Solid paints and high-thixotropy paints are used exclusively in the do-it-yourself sector. These kinds of paints are used for their decorative effects on interior walls and ceilings. In addition to its colouring effects, with solid paints a surface structuring is achieved. Solid paints can only be used with special, purpose-designed rollers. They have little tendency to spatter and so cause a minimum amount of mess. They cannot be tinted after manufacture.
Powder paints are dry paint formulations which are prepared by mixing them with water shortly before application. They are used for both interior and exterior applications.
Powder paints have a number of environmental and economical advantages such as free from solvents and preservatives, reduced weight and packaging volume, low-cost packaging and stability against frost during storage.
Paint-stripping pastes support and facilitate the removal of old coatings, by a partial dissolving effect or a chemical reaction. They reduce the hardness and adhesion of coatings onto their substrates. Subsequent mechanical removal is then greatly improved.
The following properties of Tylose are essential for the optimization of coating materials:
Thickening / Adjustment of consistency
Water retention
Function as a protective colloid
Binding power
Furthermore, open time, spattering, levelling, hiding power and film formation of the coating material are enhanced by the use of Tylose.
Interior paints
Paints, in particular with a high pigment volume concentration (PVC), owe their good processing properties to Tylose®.

Ceramics
Tylose cellulose ethers are used by the ceramic industry in various applications such as ceramic and powder metallurgical extrusion mixes as rheology modification and water retention additives.
