Technical Details & Test Data
- Mixing ratio with poly-isocyanates
Assuming equivalent reaction of the reactive groups (NCO:OH = 1:1), the following formula
applies for the calculation of the added amount of polyisocyanate (relative to 100 parts by
weight of SYNTHALAT-A 147 HS, solid):
42 X 100 X 4.5
17 X NCO %
42 = molecular weight to the NCO group
17 = molecular weight of the OH group
4.5 = hydroxyl content of SYNTHALAT-A 147 HS in % relative to solid resin.
