The Afcona 4000 Series is a range of high molecular weight dispersants.
Afcona 4011 is a polymeric dispersant principally developed for stabilising inorganic pigments like TiO2, iron oxides and matting agents. It can be used in almost all solvent-based coating systems where it gives free flow viscosity with no settling issues.
An effective polymeric dispersant for stabilising inorganic and organic pigments as well as carbon blacks. It has very good stability performance through effective steric hindrance on all types of pigments. Afcona 4063 is suitable for all pigments and all resin systems, except air dry alkyd.
Afcona 4067 is a BTX free version of a high molecular weight dispersing agent, which is very effective in inorganic and organic pigments and carbon black dispersion. It has a low cloud point and good stability that leads to better transparency and deflocculating performance.
A polyurethane dispersant supplied in 100% active form. Afcona 4200 is almost solvent free, so is recommended for solvent free systems where conventional wetting and dispersing agents cannot perform with organic pigments and carbon blacks. It is also suitable for high solid coatings like PU and UV. The unique structure gives very good compatibility in systems where normal dispersants fail, like TPA and CAB.
A highly compatible, high molecular weight dispersant for difficult systems such as TPA. Its longer polymer chain provides better steric hindrance, and as a result it performs stronger in pigment stability, colour and gloss developments. Afcona 4201 has high tinting strength, cleaner colour and is nearly solvent-free.
Afcona 4474 is a very strong BTX free dispersant especially for TiO2 dispersion in oil free polyester/melamine systems. In coil and can coating applications, the use of Afcona 4474 in TiO2 dispersions will increase the whiteness as well as the hiding power of the coating, and lower the system viscosity to achieve higher pigment loading. Afcona 4474 is also very suitable for UPE and epoxy systems sue to the acid functional pigment affinity group.
