A-side · water then sucrose

Water 12.00 ÷ 9.0 = 1.3333 eq → 180.67 g PMDI

Sucrose 16.50 · OH 400 · EW 140.25 → 0.1176 eq → 15.94 g PMDI

Index 100 = 196.6 g A. Index 90 = 176.9 g · index 105 = 206.4 g.

Do not pour 1:1

The old 20–28 g A charge never paid the water. 100 g B needs 393 g A. Pour BX-02 first if sucrose is on the floor.
