Attention:
1.The base and hardener should be mixed according to the ratio and stirred thoroughly before using.
2.We will offer you special diluent or DPM if the ink need dilute.
3.The values above are based on experiments in our lab. Experiments need to be carried out in order to get proper using condition.
