2)  Alcohol Soluble Polyamide Resin

(Customer could adjust the ratio according to their formula. No recommend ratio, as different user will adjust the ratio according to their request about the ink dry speed, compatibility with other resin and pigment, cost, etc. reason. )

We checked with some ink manufacturers and were told that they don’t heat it when produce ink, only stir to dissolve the resin, normally, take around 2-3 hours.

As we checked that different user use the solvent and ratio is not same, we got several formular for your reference as below:
India Customer use TOLUENEN: MEK=50:50, 20% VAH: 80% solvent.
China Customer use MIBK:MEK:TOL=35：15：25, 25% VAH: 75% Solvent
China Customer2 use EA:NPAV=40：40, 20% VAH: 80% Solvent

5) Maleic Resin

(No recommend ratio, as different user will adjust the ratio according to their request about the ink dry speed, compatibility with other resin and pigment, cost, etc reason.)
65% Maleic Resin: 35% Solvent

6) CPP
Solvent: 100% Toluene
20% CPP: 80% Toluene

7 ) CMP45
Solvent: 100% Toluene or 100% dimethylbenzene (Most of factory use dimethyl benzene as the cost is much low)
