- Properties and Applications
TAFIGEL PUR 52 is a low viscous, solvent-free associative thickener which builds up and stabilizes viscosity by forming a network between polyurethane, binder molecules and other paint ingredients. TAFIGEL PUR 52 can be used alone or in combination with other TAFIGEL thickeners, as well as with further technology thickeners. TAFIGEL PUR 52 is recommended for use in following systems: Interior and exterior paints, latex paints, anti-corrosive paints, emulsion plasters, adhesives and putties.
Advantages of using TAFIGEL PUR 52:
- thickening independent of pH
- excellent application properties
- good flow, leveling and gloss
- good spatter resistance
- very good color acceptance on tinting
- easy handling due to low viscosity of TAFIGEL PUR 52
The performance of polyurethane thickeners is affected by many factors including binder type, co-solvents, coalescing agents, surfactants/wetting agents, pigments and flattening agents. The interaction of TAFIGEL PUR 52 with these compounds allows varied possibilities for rheology adjustment.
- Recommended Levels and Use
TAFIGEL PUR 52 can be added at any time during the manufacturing process. A predilution with water is possible but in most cases not necessary. Ladder studies are recommended to determine optimum level. Normal dosage ranges from 0.3 - 2 % on total formulation.

- Storage and Handling
TAFIGEL PUR 52 is not sensitive to freezing. The product should be stored cool and dry. During storage a creamy layer is formed on the surface. Consequently TAFIGEL PUR 52 has to be stirred properly before use. The minimum shelf life in closed containers is 15 months from the date of manufacture.
