Surfactants Used Before Coating:

surfactant 
applied to immersion degreaser, tow-component powdery and liquid degreaser

RQ-225/RQ-225C/RQ-225D Green easily rinsing surfactants

Used at normal or heated temperature, low viscosity, have good dispersant in solid contents. Low temperature cold water solubility, uniquely superior rinsing property, excellent biodegradability, environmentally friendly, stronger degreasing force than NP, OP series surfactant, acid & alkaline resistant can be formulated to produce. Eco-friendly high quality degreaser when combined with conventional auxiliary. 
It can eliminate and prohibit poor coating adhesion and undesirable following finishing process caused by bad rinsing in pretreatment degreasing, it is the common but easily ignored problem in metal pretreatment that the following surface finishing process doesn't go smoothly as the bad rinsing property of the degreaser.

RQ-1226B/RQ-1226BH Surfactants for middle temperature degreasing

Used at middle and higher temperature, strong degreasing force, strong alkaline resistance, can be formulated to produce high quality degreaser combined with conventional auxiliary. Have excellent detergency of machine greasy dirt.
