The product is also used in pure UV curing coatings to improve the adhesion on critical substrates as plastic, metal and exotic woods.
EBECRYL® 4250 is suitable for the formulation of moisture-curing one-component polyurethane coatings, especially for one-component adhesion primers.
Formulations with EBECRYL® 4250 can be used for:- Adhesion promotion in UV/EB curing coatings
- UV/EB curable, two component polyurethane coatings
- One component adhesion primer EBECRYL® 4250 can be combined with hydroxyl functional resins to formulate coatings which cure by dual processes; UV/EB induced polymerization and NCO/OH reaction.

Storage & Handling
- Storage and Handling
- Care should be taken not to expose the product to high temperature condition direct sunlight, ignition sources, oxidizing agents, alkalis, acids or water. 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. Wash thoroughly after handling. Keep container tightly closed. Use with adequate ventilation. See the SDS for the recommended storage temperature range for EBECRYL 425. Please refer to the allnex Guide to Safety and Handling of Acrylate Oligomers and Monomers for additional information on the safe handling of acrylates.
