- Product Applications
- EBECRYL® 4740 is used in the formulation of radiation-curing coatings (UV and electron beam) for the coating of wood, plastics, and mineral substrates via the roller, spray, and curtain coating processes.
- Due to the elastic properties of EBECRYL® 4740, the product is especially suitable for coatings on flexible substrates or as an additional binder to modify the elasticity of radiation curing coatings.
- Formulation Stability
- Depending on the application, the coating can be adjusted to the appropriate viscosity using standard reactive diluents such as dipropylene glycol diacrylate (DPGDA), 1,6-hexanediol diacrylate (HDDA), isobornyl acrylate (IBOA), and trimethylolpropane triacrylate (TMPTA) or solvents such as butyl acetate.
- EBECRYL® 4740 coating formulations require less reactive diluent, and thus the binder properties are retained over a broad range of viscosities. Application at higher temperatures is also possible.
- The reactive diluent must be selected carefully as it may impact considerably on the properties and storage stability of the coating. Because of the many potential combinations with reactive diluents and solvents, compatibility must be tested in each individual case.
- UV curing of coatings formulated with EBECRYL® 4740 requires the addition of standard commercial photoinitiators. Typical levels are 4-6%, though this may vary to meet the reactivity requirements of the application. In the case of EB curing, a low oxygen atmosphere must be ensured to avoid surface inhibition.
- Lower gloss coatings can be produced using standard matting agents. EBECRYL® 4740 should be taken with respect to sedimentation, which may cause the coating to gel prematurely.

Storage & Handling
- Storage Conditions
- The maximum recommended storage temperature for EBECRYL® 4740 is 4°C to 40°C (39°F to 104°F). Care should be taken not to expose the product to high temperature conditions, direct sunlight, ignition sources, oxidizing agents, alkalis or acids. Prevent inadvertent contact with peroxides and other radical initiators and contact with copper, copper alloys, carbon steel, iron and rust. This might cause uncontrollable polymerization of the product with the generation of heat.
- Storage and handling should be in stainless steel, amber glass, amber polyethylene or baked phenolic lined containers. Procedures that remove or displace oxygen from the material should be avoided. Do not store this material under an oxygen-free atmosphere. Dry air is recommended to displace material removed from the container.
- EBECRYL® 4740 can become hazy upon storage. This haze is reversible by stirring and/or oven heating to a maximum of 60°C.
