EBECRYL® 3503

EBECRYL® 3503 is characterized by:

• Light color
• Fast cure response
• Good wetting of pigments, matting agents, and substrates

UV/EB cured properties based on EBECRYL® 3503 are characterized by the following performance properties:

• High surface hardness
• High gloss
• Good chemical resistance
• Water resistance

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

Formulated UV/EB curable products containing EBECRYL 3503 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® 3503 is suggested for use in:

• Coatings for paper, rigid plastics (i.e. polycarbonate), metal
• Wood fillers and sealers
• Pigmented coatings
• Low gloss overprint varnishes

EBECRYL® 3503 - Viscosity Reduction With Reactive Diluents:

Viscosity Reduction: 

• Graph shows the viscosity reduction of EBECRYL® 3503 with propoxylated glycerol triacrylate (OTA-480), trimethylolpropane triacrylate (TMPTA), and tripropylene glycol diacrylate (TPGDA).
• .Although viscosity reduction can be achieved with non-reactive solvents, reactive diluents are preferred because they are essentially 100 percent converted during UV/EB exposure to form a part of the coating or ink, thus reducing solvent emissions.
• The specific reactive diluents used will influence performance properties such as hardness and flexibility.

• 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.
