EBECRYL® 898

EBECRYL® 898 is a specialized type of polyester acrylate resin used in UV energy curable coatings, particularly for achieving matte finishes. Here are some key points from the provided technical datasheet:

Description: EBECRYL® 898 is a 100% solids polyester acrylate resin designed to produce matte finishes in UV energy curable coatings. It enables ultra-matte coatings with gloss levels of less than 5 (measured at a 60° angle).

Performance Highlights:

• • Extends matting effect
  • Low viscosity
  • Low odor
  • Fast cure

Performance Properties of Cured Products:

• • Provides outstanding matte effect
  • Ensures toughness and adhesion
  • Exhibits high surface hardness

Suggested Applications:

• • Wood finishes
  • PVC flooring
  • Plastic films
  • Overprint varnishes (OPVs) for paper and plastic

Viscosity Reduction: EBECRYL® 898's viscosity can be reduced using reactive diluents like dipropyleneglycol diacrylate (DPGDA), 1,6-hexanediol diacrylate (HDDA), octyl/decyl acrylate (ODA-N), trimethylolpropane triacrylate (TMPTA), and tripropylene glycol diacrylate (TPGDA). This reduction helps in application and processing.

Typical Properties:

• • Acid value: ≤ 20 mg KOH/g
  • Appearance: White liquid
  • Density at 25°C: 0.8 g/cm³
  • Functionality (theoretical): 4
  • Oligomer content: 84% by weight
  • Viscosity at 25°C, 20 s-1: ~4000 mPa.s

Precautions: Before usage, refer to the Safety Data Sheet (SDS) for information on identified hazards, recommended personal protective equipment, and handling procedures.

Storage and Handling: Care should be taken to avoid exposure to high temperatures, direct sunlight, ignition sources, oxidizing agents, alkalis, or acids. Storage containers should be made of suitable materials like stainless steel, amber glass, amber polyethylene, or baked phenolic lined containers. It's important to maintain adequate ventilation during usage and to wash hands thoroughly after handling.
