UCECOAT® 7856

UCECOAT® 7856 is a new high-solids and solvent-free radiation curable polyurethane dispersion in water suitable for high gloss applications with excellent clarity and distinctness of image (DOI). The product has an excellent colloidal stability (shelf life of 12 months) and complies with VOC-free, tin-free Does not contain intentionally added organic tin compounds and stenomer Chemically well-defined monomeric or multi functional acrylates, with low molecular weight and very narrow molecular weight distribution free requirements. Due to its low viscosity and its good responsiveness to rheology modifiers, it can be easily applied by spray, roller or curtain coating operation. The product can be advantageously applied in one single coat and does not require sanding, although it can still benefit from polishing. The cured coating exhibits good chemical and scratch resistance required for high-end wooden furniture topcoats, though it is also suitable for other substrates and applications.

Product Performance

UCECOAT® 7856 is characterized by the following properties:

  • High solids with a low viscosity
  • Excellent colloidal stability
  • Tin-free and stenomer-free composition
  • Easy to formulate with additives
  • Good leveling after application
  • Good water release upon drying
  • Good water resolubility before cure.

UV/EB cured formulations based on UCECOAT® 7856 are characterized by the following performance properties:

  • High gloss and distinctness of image (DOl)
  • High clarity and low yellowing
  • Good hardness and scratch resistance
  • Good stain and chemical resistance

The final properties of UV/EB energy cured formulations also depend on the selection of the other components such as additives and photo initiators.
