EBECRYL® 117

EBECRYL® 117 is a hydroxy functional monoacrylate, primarily used in ultraviolet light (UV) or electron beam (EB) curable coatings to enhance flexibility and improve adhesion. Here's a breakdown based on the provided technical datasheet:

Introduction:

• EBECRYL® 117 is an aliphatic mono-functional diluting acrylate with low odor, recommended for UV or EB curable coatings.
• It is particularly effective in increasing flexibility and enhancing adhesion.

Performance Highlights:

• Low odor and low viscosity, making it easy to work with.
• Exhibits high flexibility and reactive through the hydroxyl group.
• UV/EB cured coatings based on EBECRYL® 117 offer good flexibility, adhesion, and low residual odor.
• The properties of cured products also depend on other formulation components such as reactive diluents, oligomers, additives, and photo initiators.

Suggested Applications:

• Developed for formulating dual cure coatings and improving adhesion of acrylic resins.
• Recommended for use in acrylic adhesives, acrylic paints, and improving adhesion onto melamine surfaces.

Typical Values:

• Viscosity at 25°C: Approximately 70 mPa.s
• Color: APHA 100
• Hydroxyl value: 160 mg KOH/g
• Estimated glass transition temperature (Tg) of homopolymer: -50°C

Precautions:

• Toxicological properties are not fully determined; however, products of this type can be eye and skin irritants and may cause sensitization or allergic responses.
• Appropriate precautions should be taken to avoid eye and skin contact and inhalation of aerosols or vapors.
• Refer to the Safety Data Sheet for detailed handling procedures and protective equipment.

Storage and Handling:

• Avoid exposing radiation curable products to temperatures exceeding 40°C for prolonged periods or direct sunlight to prevent uncontrollable polymerization.
• Store and handle in suitable containers such as stainless steel, amber glass, amber polyethylene, or baked phenolic lined containers.
• Use dry air to displace material removed from the container.
• Shelf life is recommended not to exceed 2 years.

Statutory Labeling:

• Refer to the Safety Data Sheet for statutory labeling information.

Overall, EBECRYL® 117 offers desirable properties for formulating UV or EB curable coatings, with specific emphasis on flexibility enhancement and improved adhesion. Proper handling and storage precautions are necessary to ensure its effectiveness and safety during use.
