EBECRYL® 140

EBECRYL® 140 is a reactive diluent that is compatible with a wide range of acrylated resins used in UV/EB curing applications. Effective levels of EBECRYL® 140 typically range from 10% to 30%, depending on the application. In lithographic inks and varnishes it is quite effective in adjusting viscosity while maintaining or improving cure response and physical properties. The high functionality of EBECRYL® 140 provides increased crosslink density in UV/EB cured coatings, which can help improve gloss, hardness, and durability.

EBECRYL® 140 is characterized by:

• Light color
• Good cure response
• Low irritancy

UV/EB cured products based on EBECRYL® 140 are characterized by the following performance properties:

• Flexibility while retaining hardness
• High abrasion resistance
• Good chemical resistance

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

• 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.
