CYD carbon black dispersant for N220 is better than BYK-190.
When used as N220 carbon black dispersant, the best dosage of CYD-V021 was 10-20%(Additives/Carbon Black), while BYK-190 was 130-150%(Test result same with BYK-190 Introduction).
Dispersion performance of CYD-CV021 with addition amount of 5% was 1.4% higher than BYK-190 with amount of 20%, while BYK-190 with addition amount of 5% didnít work at all.
Dispersion performance of CYD-CV021 with addition amount of 10% was 10% higher than BYK-190 with amount of 30%, 9.6% higher than best dosage amount 150%, while BYK-190 with addition amount of 20% was weak.
Decreasing dosage of CYD-V021 to disperse LS430, performance was steady, no settling, no foam on surface, while BYK-190 was much foam and hard to disappear, solution layered and sagged apparently, only at dosage of 150% can reach good dispersion performance without foam.
