Special Properties
  • Daotan TW 6450/30WA is recommended as the NMP / NEP- free alternative for Daotan (V)TW 1236. Alike latter Daotan TW 6450 is a polycarbonatebased, high molecular weight Polyurethanedispersion. Dried at ambient temperature Daotan TW 6450 is providing clear, crack- free films without further addition of organic solvents or additives. These films exhibit excellent elasticity and mechanical properties as well as very good adhesion to different plastic substrates like e.g. ABS, PC, PA, PVC, PC/PBT, ...
  • Accordingly Daotan TW 6450/30WA is particularly recommended for waterborne plastic primer and waterborne auto OEM Basecoats with outstanding requirements in terms of stone chip resistance properties. A further use is as modifier resin to improve stone chip resistance properties of e.g. auto OEM primer surfacer formulations.


Daotan TW 6450/30WA provides unlimited dilutability with deionized water, compatibility with organic solvents is limited; e. g. butyl glycol or butyl diglycol cause a strong swelling of Daotan TW 6450. With Proglyde DMM Daotan TW 6450 is completely incompatible. According to our experience Dowanol DPM is a quite suitable diluent. In general it is recommendable to pre-dilute the solvent with deionized water before adding to Daotan TW 6450.


Compared to Daotan (V)TW 1236 Daotan TW 6450 provides quicker drying speed at ambient temperature. Properties like adhesion to different plastic substrates, mechanical properties and humidity resistance are in the same range.

Storage and Handling
  • At temperatures up to 25 °C storage stability packed in original containers amounts to at least 365 days.
  • It is important to protect Daotan TW 6450/30WA from frost; at low temperatures it has therefore to be stored under frostproof conditions. Lowest storage temperature: 5 °C
