Besides silicone surfactants amine,
antioxidants can contribute to fogging. For hydroxyl
or amine reactive amines with low fogging tendency. |
The foams can be prepared by hand mix
laboratory procedure or with a stirrer of 2" diameter at
2500 rpm. The polyol. diethanolamine, silicone surfactant and
amine catalyst were blended for 1 minute and with the
isocyanate for 7 seconds. |
