Performance Highlights
  • UV/EB cured coatings based on EBECRYL® 4201 are characterized by the following performance properties:

 

High elasticity

Good chemical and mechanical resistance properties

Outstanding abrasion resistance, in particular according to the grit feeder method

 

  • The actual properties of UV/EB energy cured products also depend on the
  • selection of other formulation components such as reactive diluents, additives and photo initiators.

Product Application

EBECRYL® 4201 is used in formulation of UV/EB energy curable coatings for application by roller coating, spraying and curtain coating on wood, cork, furniture, paper, parquet and film.

Formulating Information
  • Depending on the application, the coating can be adjusted to application 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.
  • 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® 4201 requires the addition of standard commercial photo initiators. 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. Care should be taken with respect to sedimentation which may cause the coating to gel prematurely.

Storage & Handling

Storage and Handling Conditions
  • Care should be taken not to expose the product to high temperature conditions, direct sunlight, ignition sources, oxidizing agents, alkalis or acids.
  • 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.
  • Wash thoroughly after handling.
  • Keep container tightly closed.
  • Use with adequate ventilation.
