Features & Benefits
- Advantages
- Thickening independent of pH
- Excellent flow, leveling and gloss
- Good spatter resistance
- Excellent color acceptance on tinting
- Suitable for indirect food contact applications
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 interactions of TAFIGEL PUR 82 with these compounds allow varied possibilities for rheology adjustment.

Storage & Handling
- Storage and Packaging
TAFIGEL PUR 82 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 82 has to be stirred properly before use. The minimum shelf life in closed containers is 15 months from the date of manufacture.
