EBECRYL® 4396

• Formulations with EBECRYL® 4396 can be used for:

  • UV/EB curable, two-component polyurethane coatings

  • One component adhesion primer

• EBECRYL® 4396 can be combined with hydroxyl functional resins to formulate coatings that cure by dual processes: UV/EB induced polymerization and NCO/OH reaction.
• The product is also used in straight UV/EB curing coatings to improve the adhesion on substrates such as plastic, metal, and exotic woods.

• The viscosity of EBECRYL® 4396 can be reduced using standard reactive diluents such as dipropylene glycol diacrylate (DPGDA), 1,6-hexanediol diacrylate (HDDA), isobornyl acrylate (IBOA), and trimethylolpropane triacrylate (TMPTA), and non-reactive solvents. Suitable solvents are esters, ketones, and aromatic hydrocarbons. Non-reactive solvents must be evaporated prior to curing. Only pure-grade solvents should be used (max 0.05% water). EBECRYL® 4396 should not be thinned below a non-volatile content of 40%. Prolonged storage of a solution with lower binder content may result in turbidity, sedimentation, or even gelling.
• Reactive diluents and solvents containing reactive groups such as hydroxyl or amine groups strongly influence pot life and storage stability.
• Coatings containing EBECRYL® 4396 may be applied by spraying, curtain, or roller coating at < 100g/m² coat weight. After an adequate flash-off time of solvents (if any), the coatings are UV/EB cured. This creates a tack-free and dust-dry surface. Following UV/EB curing, any post-reaction of NCO/OH groups takes place at room temperature or is forced by heat. This results in good adhesion and good mechanical and chemical resistance of the coating.
• EBECRYL® 4396 has good compatibility with esters, ketones, and aromatic hydrocarbons such as ethyl acetate, butyl acetate, methoxypropyl acetate, acetone, methyl ethyl ketone, methyl isobutyl ketone, xylene, and mixtures thereof.
• Because of the many possible combinations with thinners and solvents, the compatibility and storage stability should be tested in each individual case.

• Avoid contact with eyes and skin. Direct contact with this material may cause slight skin irritation.
• Repeated skin contact may result in sensitization and cause an allergic skin reaction. Wash thoroughly after handling.
• Keep container tightly closed. Use with adequate ventilation.

• The recommended storage temperature range for EBECRYL® 4396 is 4°C to 40°C (39°F to 104°F). EBECRYL® 4396 should be taken not to expose the product to high-temperature conditions, direct sunlight, ignition sources, oxidizing agents, alkalis, acids, or water.
• 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.
• The product is sensitive to moisture. Skin formation may occur in opened containers. Dry air is recommended to displace material removed from the container.
