Tylose for Paints

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.

Application Properties 
The inclusion of Tylose can improve the following properties of dispersion paints:
• Rheological properties such as levelling and spattering 
• Storage stability • Open time • Hiding power 
• Film formation 
The following properties of Tylose are essential for the optimisation of coating materials:
• Thickening / Adjustment of consistency
• Water retention 
• Function as a protective colloid 
• Binding power


Thickening / Adjustment of Consistency
Technically, the most important property of Tylose® is its capability to increase the viscosity of liquids and thus to act as a thickener. 
The thickening effect of Tylose strongly depends on its concentration (depicted in the diagram below). 
Furthermore, the influence of the degree of polymerisation (shown in the form of different viscosity levels) on the thickening effect of Tylose can be clearly seen. 
With all other parameters constant, the viscosity of Tylose solutions increases with an increasing viscosity level

Aqueous solutions of Tylose show a pseudoplastic effect (shear thinning), which means with an increase in shear rate, the viscosity of the solutions declines. 
This pseudoplasticity is specific to each Tylose type and the respective viscosity of the grade. 
High viscosity Tylose grades have a stronger shear thinning effect than those of low viscosity.


Thickening / Adjustment of Consistency

Tylose ensures the required consistency for application by providing a certain rheological profile or flow property. 
This makes the application of paint easy. The amount of Tylose as well as its viscosity determines the viscosity level and leads to optimal application properties. 
During application, a decreasing viscosity with increasing shear stress is desirable. 
The pseudoplasticity serves to optimise application properties of the coating system with respect to rolling, brushing resistance and spattering behaviour. 
For interior paints with low spattering the use of hydrophobic modified Tylose is recommended. 
Through the associative thickening effect with the binder, the viscosity at high shear rates will be increased, thus reducing the spatter. 
The correlation of the rheology profile of a paint and the application properties can be supplied by our technical staff.


Because of its thickening effect in coatings, Tylose acts as a stabiliser for the dispersed components. 
The formation of serum, i.e. the tendency to precipitate displayed by insoluble components such as pigments and fillers etc., is slowed down or even stopped completely. 
As a result, the coating material is protected against slow sedimentation of its components and is also stable during storage.

Water Retention
An important property of Tylose is its pronounced water retention capability. 
It prevents the water from penetrating into the absorbing substrate too quickly which results in a better adhesion to the substrate. 
To the greatest possible extent, the water will be retained in the coating material during drying. 
A uniform film formation is ensured and incipient cracking is avoided. 
Particularly in formulations with high pigment volume concentration, the water retaining effect of Tylose ensures sufficient open time for application. 
Adequate water retention in paints depends mainly on the concentration and viscosity level as well as on the type and temperature of the substrate.

Function as Protective Colloid
Coating materials are predominantly dispersions of pigments and fillers in an aqueous medium. 
Tylose acts as a protective colloid by preventing the agglomeration of the solid particles. This leads to a better storage stability and easier agitation of the paint. 
Due to its molecular structure and its specific properties, Tylose is a highly effective protective colloid. 
It is widely used in other application fields, such as polymerisation, to avoid the coagulation of the polymer.

Binding Power
Especially in distempers, Tylose acts as a binder by combining the solid particles and binding them to the substrate. 
Tylose has strong adhesive power, good dry binding power and dry adhesion. For these reasons, Tylose ensures a good adhesion between the coating and substrate.

SE Tylose GmbH & Co. KG is one of the major manufacturers of cellulose ethers world wide, supplied under the brand name Tylose. 
Tylose is used in a wide variety of products and applications.

Construction materials are optimised with the following properties of Tylose:
• Water retention 
• Stabilising of air pores
• Consistency control 
• Improvement of workability
• Adhesion improvement


Cementitious thin bed adhesives are used to adhere ceramic tiles, to build walls of aerated concrete or lime stone bricks and to install exterior insulating finishing systems (EIFS). 
They offer an easy and light workability, a high efficiency and guarantee a long durability.


Cement tile adhesives have to be easy to trowel. They must provide long embedding time, high slip resistance and sufficient adhesion strength. 
These properties can be influenced by Tylose MC. 
Adhesives for block laying are used to build up walls of aerated concrete blocks, sand-lime bricks or standard bricks. 
EIFS adhesives ensure an excellent bond between substrate and insulating boards. 
Tylose MC improves the workability of EIFS adhesives and increases both adhesion and sag resistance.

Cement based Renders and Trowelling Compounds
Renders are mixtures of mineral binders, aggregates and auxiliaries. 
Depending on the process, there is a distinction between hand and machine application. 
Renders are used for base coating, insulation, renovation and decorative purposes. 
Renders based on cement or cement/hydrated lime can be employed for exterior and interior work. 
Cement based jointing and trowelling compounds are used for repairing systems and to smooth coarse walls and floors. 
Grouts are applied to fill the gaps between ceramic or stone tiles.


Tylose MC is an important additive ensuring there is sufficient water retention in renders and trowelling compounds. 
Additional advantages are better workability and an increase of the adhesion strength. 
Machine applied renders are mixed in continuously or discontinuously working plastering machines. 
These enable coverage of large wall and ceiling areas by a highly efficient technique. 
Continuously operating plastering machines need to be fed with premixed renders containing Tylose. 
Other additives (e.g. Hostapur OSB, Tylovis SE 7 or Tylovis EP 28) can be added as required.

Thickening/Adjustment of Consistency 
Tylose can thicken and adjust the consistency of hair conditioners, hair gels, toothpastes and lotions


The thickening effect of Tylose grades is dependent on the degree of polymerisation (DP) or the molecular weight and the concentration used. 
When using the same concentration, the viscosity of the solution increases with an increased degree of polymerisation. 
An increase in Tylose concentration gives a strong increase in viscosity

Aqueous solutions of Tylose grades are shear thinning liquids. 
The viscosity is decreased by an increase in shear stress, and returns to its initial viscosity when the shear stress is removed. 
High viscosity Tylose grades have a stronger shear thinning effect than those of low viscosity, which is shown in the diagram below. 
The rheological profile varies depending on the Tylose type used, e.g. Tylose H or Tylose MO

Stabilisation

Emulsions are commonly used in the field of skin care. 
A finely distributed mixture of oil and water, two liquids which are normally immiscible, exists in an emulsion without any visible segregation. 
One liquid exists as little droplets distributed within the other liquid. 
Either water in oil emulsion (W/O emulsion) or oil in water emulsion (O/W emulsion) is possible depending on which phase the droplets are formed in. 
The preferred stabilisers for O/W emulsions are thickeners that act in the water phase. 
The surface activity of Tylose is low compared to tenside products. 
However, due to its thickening effect and colloidal protective properties, Tylose offers an important contribution to the stabilisation of the emulsion formed. 
The use of low to medium viscosity Tylose H types are preferable in this case.


High Compatibility

Non-ionic Tylose H, MH, and MO types exhibit a good compatibility with numerous tensides. 
Furthermore, they are also compatible with many other raw materials such as starch, dextrin, gelatine, sorbitol and propylene glycol. 
Due to their chemical structure, Tylose grades exhibit good compatibility with electrolytes. 
Soluble phosphate, carbonate and sulphate exhibit a stronger flocculating effect in higher concentrations than nitrate and chloride. 
The electrolyte compatibility of Tylose H grades with chlorides is generally higher than that of Tylose MO grades. 
In addition AlCl3 gives a higher thickening effect with Tylose H grades (see diagram below).

Although Tylose is insoluble in most organic solvents, it exhibits relatively good solubility in water/organic solvent mixtures, such as water with ethanol, isopropanol or glycerol, even when relatively high fractions of the organic solvent are present. 
The following diagrams show the development of viscosity in water with ethanol, isopropanol and glycerol using Tylose H or MO grades.
