Additional Information
- Chemical nature
- cycloaliphatic diamine
- Advantages
- very low reactivity towards isocyanate groups, reduces the curing time at both ambient and higher temperatures by about 50%
- Storage
- Vestamin A 139 can be stored in unopened containers for at least one year without loss of quality
- Handling
- For systems based on Vestanat IPDI it is recommended to use an amount of Vestamin A 139 equivalent to 50-60% conversion with isocyanate groups.As a general rule, approximately 1.5 g Vestamin A 139 should be used for every 1 g of NCO in the formulated paint.
