SCHWEGO® thix 8315

Rheologal additive for solvent borne coating systems

Chemical base: Organically modified aluminium derivative
Properties: SCHWEGO thix 8315 increases the viscosity of binders in solvent borne systems and causes pseudoplastic rheology. SCHWEGO thix 8315 acts only on binders containing ester-, hydroxyl- or other functional groups, which are able to form hydrogen bonds. Polar solvents may have an influence on the effectiveness.
Applications: SCHWEGO thix 8315 is suitable for thickening of all common solvent containing binder systems with polar groups. It is particularly suitable for high build systems, stoving paints and DIY-paints. The main advantages are:

Liquid, easy incorporation
Temperature stable
No influence on gloss
Prevents settling and sagging
Technical data:
(Guide values)
Appearance : yellowish liquid
Density (ISO 2811-1) : 0,97 g/cm³
Flash Point (ISO 1523) : 85 °C
Processing: Add SCHWEGO thix 8315 slowly under constant stirring. Thorough mixing is necessary in order to avoid uneven reaction and subsequent formation of gelled particles. Therefore, it is recommended to add SCHWEGO thix 8315 before dispersion. The final viscosity is reached after approximately 24 hours. Post addition for viscosity adjustment is possible, if homogeneous distribution is guaranteed. The quantities varies with the reactivity of the binder and the necessary viscosity. The recommended dosage is between 0.2 – 2.0 %, for printing inks 0.5 - to 6.0 %.
Storage: Keep SCHWEGO thix 8315 in a cool, well-ventilated place. Store SCHWEGO thix 8315 in well closed containers in a dry location as it is sensitive to moisture and will be decomposed. Subject to appropriate storage, the described properties of SCHWEGO thix 8315 remains stable for at least 12 months, in unopened original drums.
Packaging: 25 kg can
