- Properties and Applications
TAFIGEL PUR 41 is designed as an "associative thickener" which builds up and stabilizes viscosity by forming a network between polyurethane, binder molecules and pigment particles. TAFIGEL PUR 41 can be used alone or in combination with other TAFIGEL thickeners as well as with further thickener technologies. TAFIGEL PUR 41 is recommended for use in following systems: Interior and exterior paints, latex paints, anti-corrosive paints, emulsion plasters, adhesives and joint fillers.
Advantages of using TAFIGEL PUR 41:
- thickening independent of pH
- excellent brush handling
- good flow, leveling and gloss
- good spatter resistance
- very good color acceptance on tinting
The thickening effect of polyurethane thickeners can be affected by many factors including binder type, co-solvents, coalescing agents, surfactants/wetting agents, pigments and flattening agents. The interactions of TAFIGEL PUR 41 with these compounds allow varied possibilities for rheology adjustment.
- Recommended Levels and Use
TAFIGEL PUR 41 can be added undiluted to the grind and before adding the binder. For post-addition, the preparation of a masterbatch is possible with water. Ladder studies are recommended to determine optimum levels. Normal dosage ranges from 0.3 - 2 % on total formulation.

- Storage and Handling
TAFIGEL PUR 41 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 41 has to be stirred properly before use. The minimum shelf life in closed containers is 15 months from the date of manufacture.
