UCECOAT® 7655

UCECOAT® 7655 is a radiation curable polyurethane dispersion which is tack-free before cure and after water evaporation. It has been developed for high end wooden furniture top-coats, both transparent and pigmented, but can also be used for other applications and substrates, such as field applied UV curable coatings for wood, concrete, VCT (vinyl composition tile), and resilient floors. This polyurethane dispersion is very reactive and exhibits very good scratch resistance. Due to the low viscosity, it can be applied by spray or curtain coater.

Features & Benefits

Product Features
Product Performance

UCECOAT® 7655 is characterized by:

  • Translucent to white appearance
  • Low viscosity
  • Tack-free after water evaporation and before UV curing
  • Low VOC

UV/EB cured formulations based on UCECOAT® 7655 are characterized by the following performance properties:

  • Very high reactivity in clear and pigmented systems
  • Very good hardness and high scratch resistance
  • Excellent chemical and stain resistance
  • Optimized colloidal stability
  • Good compatibility and easy to formulate.

The actual properties of UV cured products also depend on the selection of the other formulation components, such as additives and photoinitiators.

Storage & Handling

Storage Conditions

Protect the product from freezing. Care should be taken not to expose the product to high temperature conditions or direct sunlight. Containers should be kept closed and away from materials that react with water. Bacteriological contamination can occur if the product is stored for an extended period in a container which is not sufficiently sealed or clean. Storage and handling should be in stainless steel, amber glass, or amber polyethylene containers. After prolonged storage product can settle and may require agitation to re-disperse. This product is stable under normal conditions of handling and storage. Do not store this material under an oxygen free atmosphere. Wash thoroughly after handling. Use with adequate ventilation.
