Dispersant kuma ana kiransa wetting da dispersing agent.A gefe guda, yana da tasirin wetting, a gefe guda, ɗayan ƙarshen rukunin da yake aiki ana iya tallata shi akan saman pigment wanda aka niƙa shi cikin ɓangarorin lafiya, ɗayan ƙarshen yana narkewa a cikin kayan tushe don samar da Layer adsorption (the. ƙarin ƙungiyoyin tallan tallace-tallace, mafi tsayin hanyar haɗin sarkar, lokacin daɗaɗɗen tallan talla) don samar da cajin cajin (fanti na tushen ruwa) ko repusion na entropy (fanti mai ƙarfi), ta yadda za a iya tarwatsa ɓangarorin pigment kuma a dakatar da su a cikin fenti. dogon lokaci don kauce wa flocculent sake.Wannan yana tabbatar da kwanciyar hankali na tsarin fenti.
 
Nau'o'in watsawa da aka fi amfani da su.
1.Anionic wetting da dispersing wakili
Yawancin su sun ƙunshi waɗanda ba na iyakacin duniya ba, sarkar hydrocarbon da ba ta dace ba da kuma rukunin hydrophilic na polar.Ƙungiyoyin biyu suna a ƙarshen biyu na kwayoyin halitta, suna samar da sifa mai asymmetric hydrophilic da oleophilic tsarin kwayoyin halitta.Irinsa sune: sodium oleate C17H33COONa, carboxylate, sulfate (RO-SO3Na), sulfonate (R-SO3Na), da dai sauransu. Daidaituwar masu rarraba anionic yana da kyau, kuma ana iya amfani da polymers na polycarboxylic acid, da sauransu. kuma ana amfani dashi ko'ina azaman masu rarraba nau'in flocculation.

2.Cationic wetting da dispersing wakili
Su ne wadanda ba iyakacin duniya tushe tabbatacce caje mahadi, yafi amine salts, quaternary amine salts, pyridinium salts, da dai sauransu Cationic surfactants da karfi adsorption ikon da samun mafi alhẽri watsawa sakamako a kan carbon baki, daban-daban baƙin ƙarfe oxides da Organic pigments, amma ya kamata a lura. cewa suna amsa sinadarai tare da ƙungiyar carboxyl a cikin kayan tushe, kuma lura cewa bai kamata a yi amfani da su lokaci guda tare da masu rarraba anionic ba.

3.Controlled free radical type hyperdispersant
Na biyu, matsayin masu rarrabawa
1.Haɓaka mai sheki kuma ƙara tasirin matakin daidaitawa.
2.Hana launi mai iyo da fure.
3.Inganta ikon canza launi.
4.Reduce danko da kuma ƙara pigment loading.
5.Reduce flocculation, ƙara constructability da amfani.
6.Trevent recoarse da kuma kara ajiya kwanciyar hankali.
7.Increase launi yada da launi jikewa.
8.Increase transparency ko rufe iko.
9.Inganta aikin nika da rage farashin samarwa.
10.Hana zama.
