Afcona 4201

100% active. Great for all pigment types-especially organics and CB

• Great for high solids/VOC free systems including inks.
• Polyurethane dispersant supplied in 100% active form.Recommended for solvent-free systems, where conventional wetting and dispersing agents cannot perform with organic pigments and carbon blacks.
• Extremely good compatibility with thermoplastic acrylic, NC and CAB. Also great choice for ink dispersions due to solvent-free nature.
• Afcona-4201 is a result of an innovative concept of polyurethane dispersants. This innovative technology is based on an own new developed intermediate monomer and own new developed anchoring groups.

Afcona-4201 is based on the same chemical structure as ACONA-4200. Compared to Afcona-4200 it has a longer polymer tail, which proved better steric hindrance. Compared to Afcona-4200 the differences are as below:

• Afcona-4201 performs better in pigment stability and color and gloss
• Afcona-4201 has better compatibility and better performance in common resin systems such as PU, epoxy, polyester/melamine, thermosetting acrylic/melamine, alkyd/melamine, acid curing, NC and UV. However Afcona-4200 is better in more difficult systems such as thermoplastic acrylic.
• Afcona-4201 supply in almost 100% active ingredients, therefore, it is an excellent dispersant for high solid coatings like polyurethane, epoxy and UV coating.
• The almost 100% solvent-free form makes it also a very interesting dispersant for ink formulations. This due to the free choice of solvents.

Note:

• Afcona–4201 will become slightly hazy at temperatures below 5° C. Even at -15° the slight haziness stays the same. This will not influence the dispersing quality.
• There may be some slight thixotropic behavior and this is due to the catalyst that we use during polymerization. This will not influence overall the performance of Afcona- 4201.

Calculation method for the required amount of active ingredient based on pigment:

Afcona-4201 should be incorporated in the mill base before adding the pigments.

55 lbs. and 419 lbs. non-returnable containers.

Afcona-4201 should be stored in a cool, dry place.
