Performance Highlights

EBECRYL 168 is characterized by:
• Light color
• Low viscosity
• Acid functionality                                                                                                                        
UV/EB curable formulated products containing EBECRYL 168 are characterized by:
• Good adhesion to metal substrates
• Improved compatibility (relative to EBECRYL 170)                                                             
The actual properties of UV/EB cured products also depend on the selection of
other formulation components such as reactive diluents, additives and
photoinitiators.

Suggested Applications

Formulated UV/EB curable products containing EBECRYL 168 may be applied via
direct or reverse roll, offset gravure, metering rod, slot die, knife over roll, air
knife, curtain and immersion coating methods.

EBECRYL 168 is recommended for use in:
• General metal coatings and primers
• Coatings for galvanized pipe and tube
• Coil coatings
• Solder resist formulations

Notes on usage

Typical usage level is between 1% and 5% by weight of the total formulation. Due to its acidic character, EBECRYL 168 can undergo hydrolysis, and therefore formulations containing EBECRYL 168 should be protected from humidity. Since EBECRYL 168 can react with alkaline materials, free amines, amino acrylates, basic pigments and N-vinyl-2-pyrrolidone should not be used in combination with EBECRYL 168. Formulations may exhibit turbidity with the addition of EBECRYL 168, though such turbidity may not be immediately apparent. The presence of turbidity is not normally indicative of coating performance problems, though in severe instances, separation or precipitation may occur.

Storage & Handling

Storage and Handling

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.
Contamination of EBECRYL 168 with acetone or other ketones can cause
coloration of the product during storage.
