EBECRYL® 80

EBECRYL®80 is characterized by:

• Very fast cure response
• Low viscosity
• Light color

UV/EB cured products containing EBECRYL®80 are characterized by the following performance properties:

• High gloss
• Good solvent resistance
• Low residual odor

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

Formulated UV/EB curable products containing EBECRYL®80 may be applied via direct or reverse roll, offset gravure, metering rod, slot die, knife over roll, air knife, curtain, immersion and spin coating methods as well as flexographic and screen printing.

EBECRYL®80 is recommended for use in:

• Fast curing overprint varnishes
• Clear coatings for wood, paper and plastics
• Top coats for wood
• Flexographic inks and coatings
• Screen inks and coatings
• Wood fillers

⁵ EBECRYL 810 is a tetrafunctional polyester acrylate, product of Allnex
⁶ Parts by weight
⁷ EBECRYL 81 is a 2.5 functional amine modified polyether acrylate, Allnex
⁸ EBECRYL 83 is a tetrafunctional amine modified polyether acrylate, Allnex
⁹ 2-hydroxy-2-methyl-1-phenyl propanone, e.g. Speedcure 73 product of Lambson
¹⁰ Benzophenone
¹¹Coatings were applied to aluminum test panels at ~12 μ thickness and cured with one 300 watt/inch Fusion H lamp at the minimum UV energy required to achieve a mar free surface.

• Table 1 compares the cure response of EBECRYL 80 with a polyester acrylate other polyether acrylates and demonstrates the faster reactivity of amine modified polyether acrylates. EBECRYL 80 is notable for exhibiting the highest reactivity.

• 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.
