Chroma (Gardner)	≤8
The boiling point	250ºC
Flash point	NO

Application areas:
1. Disperse and grind carbon black, organic pigment and through-iron in high-end industrial paint systems (plastic, wood, floor and coil steel, etc.)
2. Used for dispersing grinding carbon black and organic pigments in various ink systems, especially alkyd polyurethane ink system;
3. Grinding and dispersing of color powder of polyether/polyester polyol color paste system;
4, the preparation of unsaturated resin color paste;
5, solvent-free epoxy system black and organic pigment paste preparation
6, UV wood paint dispersion filler viscosity drop is very good, especially suitable for high powder filling high solid distribution;
Recommended dosage:
Dispersant dosage (g) = [specific surface area of pigment (m2/g) ÷ 500] × weight of pigment (g)

Types of paint	Organic pigments	Low surface carbon black	High surface carbon black
Dispersant dosage	7-15%	10-20%	40-80%

Usage: dissolve RD-9618 in the mixture of grinding base material first, and then add pigment for grinding.
