DAOTAN TW 6450/30WA is recommended as the NMP / NEP- free alternative for DAOTAN (V)TW 1236. Like the latter, DAOTAN TW 6450 is a polycarbonate-based, high molecular weight Polyurethane dispersion. Dried at ambient temperature, DAOTAN TW 6450 provides clear, crack-free films without further addition of organic solvents or additives. These films exhibit excellent elasticity and mechanical properties and 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 regarding 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 can be used as an adhesive for pharmaceutical and food packaging applications. It provides excellent peel strength and long-term humidity resistance. It is ready to use; no further formulation is needed.
