RD9880 is a resin color developer of zinc salicylate type with the rapid color developing speed in low temperature and the excellent aging resistant performance. Meanwhile, it maintains characteristics of low viscosity, easy formula and low foaming trend, which is widely used in carbonless copying paper industry.
CF paste process: add and stir water in the tank, then put into the dispersant and solid materials and mix to keep even distribution at the high speed. Slow down the stiring speed to add the prepared starch gum and then mix for 15-20 mins. The next step is to adjust PH value to 8.0-8.5 and pour into the resin color developer slowly, mix them for a certain period to get the even distribution. Finally add SBR latex slowly and mix the paste for 15-20 mins. The PH value of the prepared CF paste is 7.0- 7.5.
