DeCAL 4288 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.

- Applications
- DeCAL 4288 should be used as the sole resin component of pigment grinding bases that are subsequently to be used as the basis for water-based flexographic inks.
- Bases prepared on DeCAL 4288 are free flowing systems at 60-70 seconds on a B4 Ford Cup at 20ºC. Optimum results will be achieved with the most efficient grinding equipment. DeCAL 4288 is also suitable for use as a vehicle in the let-down stage and provides excellent rub resistance and transfer properties. DeCAL 4288 is compatible with virtually all pigments suitable for water applications.
- DeCAL 4288 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 4288 may be used as sole ink binder where very good resolubility is required or simply as a modifier to improve the resolubility of more hydrophobic inks.
- DeCAL 4288 is also suited for use as binders and modifiers for other systems such as waterbased paints and coatings for use in the art and craft, and paper coatings industries. The polymer can act as a gloss promoter in waterbased paint systems, whilst also being suitable for use in temporary protective and removable coating applications.
