Technical Details & Test Data
- Properties
POLURENE T70 can be diluted with esters and aromatic solvents up to 10-15%, without any precipitation process, whereas with aliphatic solvents like white spiritit is recommended not to dilute the product below 30% solid content. Usually such a low concentration of POLURENE T70 is used as reactive thinner in order to improve the characteristics of paints based on short and medium air drying alkyd resins.
In order to reduce the drying time of the systems based on POLURENE T70, it is advisable to use some Dibutiltindilaurate (DBTL), calcium octoate, etc. POLURENE T70 can be used in combination with saturated polyester and alkyd resins of our REXIN range as well as Hydroxylated acrylic polyols. Thanks to brightness, flexibility, and mechanical resistance POLURENE T70 can also be used for car repairing coatings.
Storage & Handling
- Shelf Life
- 12 Months
- Storage and Shelf Life
In sealed drums we guarantee a storage life of 12 months, provided POLURENET70 is stored under dry and cool condition. Once opened the product should be used rapidly, because like all isocyanates, it is sensible to moisture.
