AFCONA – 5281 is an effective dispersing agent for organic and carbon black pigments. It stabilizes pigments through steric hindrance. It’s high solids content also makes it suitable for low VOC coatings applications. Afcona-5281 can be used as the sole dispersant in pigment concentrates or be combined with other high molecular weight dispersants, such as AFCONA – 4071 or AFCONA – 4701, in order to optimize compatibility and cost. Afcona-5281 can also be used as a post add in systems to achieve improved pigment stability. The advantages of AFCONA – 5281 are:
- Lower grind viscosity.
- Better compatibility, especially in difficult resin systems such as NC, CAB and others.
- Compatible with all resin systems.
- Good pigment stability during storage. AFCONA – 5281 is not designed for high load levels of inorganic pigments and fillers as the mill based viscosity will become high. It can be used for inorganic pigment and fillers if the load level is low in the mill base.
Note: AFCONA – 5281 will become hazy at temperature 5C or below. Heat up to 50°C and mix well before use. This will not influence the quality.
