Palmer Holland - EBECRYL 168

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

Product 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

Properties

Physical Form

Liquid

Notes

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 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.

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