Features & Benefits

Performance Highlights
  • UCECOAT 2804 has been developed as a binder for water-based overprint varnishes and inks where low viscosity and water re-dispersibility before cure are important.
  • The low grits content ensures easy product filterability combined with a good colloidal stability. This product is very reactive and can be cured with mercury or with UV LED lamps.
  • The cured coating is hard and exhibits outstanding mechanical and chemical resistance in clear or pigmented applications. Its regulatory compliance and low migration potential make it particularly suitable for indirect food contact packaging or label markets.

Storage & Handling

Storage and Handling

The recommended storage temperature range for UCECOAT 2804 is ≥4°C (39°F) to ≤40°C (104°F). 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.
