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 calculation of the amount of polyisocyanate to be added (relative to 100 parts by
weight of solid Synthoester 1690):
Amount of polyisocyanate 42 X 100 x 1,8
to be added: 17 x NCO %
42 = molekular weight of the NCO group
17 = molecular weight of the OH group
1,8 = hydroxyl content of SYNTHOESTER 1690 in % relative to non-volatile components
Best results are obtain with a mixing ratio of:
100 parts by weight SYNTHOESTER 1690 with
27 parts by weight Desmodur N- Compatibility
Synthoester 1690 is compatible with the polisocyanates Desmodur N, L and IPDI-Trimer. In
addition the polyester is compatible with pigment concentrations based on alkyd resin.
Nevertheless compatibility should be tested in special cases.
