EBECRYL® 741

EBECRYL® 741 is an adhesion promoting resin with excellent pigment dispersion properties specifically designed for radiation curable screen inks. It is particularly suited for general purpose applications on various treated plastic substrates. Additionally, it can be employed as a let-down resin when combined with EBECRYL® epoxy acrylates, polyester acrylates, and urethane acrylates, although compatibility issues may arise when used in amounts exceeding 10%.

Performance Highlights:

• Moderate viscosity
• Good milling properties
• Acts as a vehicle for the grind and let down
• Ensures excellent intercoat adhesion and substrate wetting when applied as a screen ink
• Cured ink exhibits good substrate adhesion, excellent intercoat adhesion, and flexibility

Suggested Applications:

• Screen inks and adhesives for challenging substrates like polyester, polypropylene, polyethylene, polystyrene, polyvinyl chloride, etc.
• End-use applications include banners, POS posters, containers, CDs, loose leaves, membranes/switches, etc.

Physical Values:

• Viscosity, Höppler 25°C, mPa.s: 3000 - 4500
• Colour, Gardner max: 4
• Density at 25°C, g/cm3: 1.05
• Appearance: Yellow liquid

Recommended Formulation: An example of a recommended formulation includes percentages of various ingredients such as EBECRYL® 741, DPHA, HDDA, EBECRYL® 7100, EBECRYL® 1290, pigment, photo initiator, and additives. Detailed information can be found in the technical leaflet.

Storage and Handling:

• Avoid exposing radiation curable products to temperatures exceeding 40°C for prolonged periods or direct sunlight to prevent uncontrollable polymerization.
• Storage temperatures below 10°C should be avoided.
• Store and handle in appropriate containers (stainless steel, amber glass, amber polyethylene, or baked phenolic lined).
• Use dry air to displace material removed from the container.
• The material should not be stored for more than 2 years.

Precautions:

• Toxicological properties are not fully determined, but products of this type can be expected to be eye and skin irritants and may cause sensitization or other allergic responses.
• Take appropriate precautions to avoid eye and skin contact and inhalation of aerosols or vapors.
• Consult the relevant Safety Data Sheet for proper handling procedures and protective equipment.
• Refer to the Safety Data Sheet for emergency and first aid procedures.

Statutory Labeling: For statutory labeling information, refer to the Safety Data Sheet.
