Recommended Levels

Recommended dosage: The following dosage is based on the ratio of dispersant solids to pigments:

Inorganic pigments: 20-30% by oil absorption

Organic pigments: green, blue, purple: 15-30% by BET value; yellow, red, orange: 25-45% by BET value

Carbon black low pigment: 15-20% by DBP absorption value

Carbon black high pigment: 50-80% by DBP absorption value

Instruksi Penggabungan dan Pemrosesan

To achieve the best performance, the additives should be added to the grind first, followed by the pigment. Premix resin dan komponen pelarut dari penggilingan, then slowly add the additives while stirring. Do not add the pigment until the additives are well mixed.
