EBECRYL® 373

EBECRYL® 373 is an epoxy acrylate resin in tripropylene glycol diacrylate (TPGDA) and propylene carbonate, primarily used as an anti-misting additive for offset inks. Here's a breakdown of its key details:

Introduction:
EBECRYL® 373 is designed to reduce the misting of offset inks, making it particularly useful in printing applications where misting can be problematic.

Suggested Applications:
Typically, around 3 to 5% of EBECRYL® 373 is added to the formulated ink. It can be added during the grinding stage or during letdown.

Performance Highlights:

• Characterized by a brown color and smooth paste aspect.
• Effectively reduces misting of UV offset inks.

Viscosity Reduction:
EBECRYL® 373 can be diluted with reactive monomers such as oligotriacrylate (OTA 480) and tripropyleneglycol diacrylate (TPGDA). The choice of reactive diluent will affect properties like hardness and flexibility.

Specifications:
Appearance: Brown paste

Typical Properties:

• Resin, % by weight: 0.99
• TPGDA, % by weight: 80
• Propylene carbonate, % by weight: 50

Storage and Handling:

• Avoid exposing to temperatures exceeding 40°C for prolonged periods or direct sunlight, as it may cause uncontrollable polymerization.
• Store in suitable containers and avoid storing under an oxygen-free atmosphere.
• Use dry air to displace material removed from the container.
• Shelf life is typically two years.

Precautions:

• Toxicological properties are not fully determined, but products of this type can 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 Safety Data Sheet for handling procedures and protective equipment recommendations.
