Thickening / Adjustment of Consistency of TYLOSE H 20 P2:
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.
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 TYLOSE H 20 P2 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 TYLOSE H 20 P2 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 TYLOSE H 20 P2 components and is also stable during storage.
Water Retention of TYLOSE H 20 P2:
An important property of TYLOSE is its pronounced water retention capability.
TYLOSE H 20 P2 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 of TYLOSE H 20 P2:
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 TYLOSE H 20 P2 molecular structure and its specific properties, TYLOSE is a highly effective protective colloid.
TYLOSE H 20 P2 is widely used in other application fields, such as polymerisation, to avoid the coagulation of the polymer.
Binding Power of TYLOSE H 20 P2:
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.
TYLOSE for Personal Care:
Personal Care products include all areas of nurturing and decorative cosmetics.
Nurturing cosmetics include hair care, skin care and oral hygiene.
Decorative cosmetics include make-up, powders, eye shadow and mascara.
In addition to the thickening effect, TYLOSE improves the foam stability of shaving foams, preserves moisture during a perm treatment, increases the stickiness of adhesive creams, acts as a binder in powder make-ups, and eases the distribution of colouring agents in hair.
Being a physiologically harmless cosmetic additive, TYLOSE offers a multitude of applications in the field of personal care.
TYLOSE hydroxyethyl cellulose (HEC) is our most widely used additive in the cosmetic field.
Besides the ultra pure cosmetic types, our standard TYLOSE types can also be used.
