LAROMER® PO 94 F

Laromer® PO 94 F is a liquid modified acrylate oligomer primarily used in the formulation of energy curable printing inks and coatings for various substrates like wood, paper, plastic, and metal. Here's a summary of its properties and applications:

Key Features & Benefits:

• Very high reactivity
• Good pigment wetting
• Low viscosity
• Good surface cure properties

Chemical Composition: Amine-modified polyether acrylate

Properties:

• Appearance: Clear, low viscous liquid
• Acid value: ≤ 0.5 mg KOH/g
• Viscosity at 23°C: 450 – 750 mPas
• Iodine color number: ≤ 2
• Density at 25°C: ~ 1.10 g/cm³
• Flash point: > 100°C

Solubility & Compatibility: Soluble in all common paint solvents except for aliphatic hydrocarbons. Compatible with most unsaturated acrylate oligomers such as other Laromer® grades.

Applications: Laromer® PO 94 F is known for its high reactivity, making it suitable for a variety of applications. It's commonly used in:

• Printing inks for flexographic, gravure, digital, or silk-screen applications
• Overprint varnishes for commercial, publication, or packaging applications
• General industrial metal coating applications
• Plastic components coating applications
• Wood coatings for floor, furniture, or millwork applications

Recommendations: Due to its amine modification, Laromer® PO 94 F enhances reactivity, especially with H-abstraction Type II photoinitiators, minimizing oxygen inhibition and improving surface curing of thin layers. It can be further diluted with low-volatile monomers for specific properties.

Safety: Standard safety precautions apply, including ventilation, skin care, and wearing protective goggles. Detailed safety information is available in the Material Safety Data Sheet.
