Product Performance

UCECOAT® 7788 is characterized by:

  • Best in class cost/performance balance
  • Excellent dispersion stability
  • Versatility in use

UV/EB cured properties based on UCECOAT® 7788 are characterized by the following performance properties:

  • Nearly tack free after physical drying
  • Excellent drying properties
  • Good chemical resistance
  • Balanced elasticity, hardness and toughness providing very good mechanical properties
  • Chemical and stain resistance

The actual properties of UV/EB cured products also depend on the selection of other formulation components such as reactive diluents, 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.
