- Chemical Family
- Carboxylated Acrylic Copolymer
DeCAL 4286 is a low molecular weight carboxylated acrylic copolymer with the capacity to carry very high levels of pigment and to provide maximum color development properties at these loadings. To obtain the full benefits of DeCAL 4286, it is essential to use the highest possible pigment binder ratios and the highest possible pigment loading.

- Stability
DeCAL 4286 bases show excellent stability with time. Good agitation is required when preparing inks from DeCAL 4286 bases. Improvements in stability can be achieved through the incorporation of a suitable sequestering agent such as DeCAL 9203 to remove any trace metal ions. This should be added directly to the DeCAL 4286 prior to addition of the pigment at a level of around 1% on the total base formula.
- Appearance
- Clear solution
- Crosslinking
DeCAL 4286 is a carboxylated acrylic polymer therefore improvements in water and solvent resistance can be achieved via crosslinking through the free carboxyl groups in the polymer. Typical crosslinkers include Zirconium compounds, UF and MF resins and carbodiimides.

- To demonstrate the benefits of base grinding using DeCAL 4286, the above inks made on the DeCAL 4286 bases were compared with similar inks made using just DeCAL 4201. As shown below using a dedicated ink grinding resin such as DeCAL 4286 provides significant improvements in color strength:-
- Phthalo blue
- 10% stronger
- Carbon black
- 18% stronger
- Lake red C
- 2% stronger
- Lithol red
- 17% stronger
- Cu ferro violet
- 48% stronger
- Cu ferro blue
- 33% stronger
- DeCAL 4286 is compatible with virtually all pigments suitable for water applications. DeCAL 4286 is compatible with most resins used in waterbased systems. This includes all acrylics, vinyl acetate, stirene acrylic and polyester resins. Some maleics and high acid value resins can be more difficult. DeCAL 4286 does not have a high tolerance for organic solvents due to its hydrophilic nature. The addition of alcohols, glycols and glycol ethers above 20% may result in precipitation of the resin.
