LAROMER® LR 8986

Laromer® LR 8986 is a modified aromatic epoxy acrylate oligomer designed for the formulation of energy-curable printing inks and coatings for various applications such as wood, wood products, paper, and plastic. Here's a summary of its properties and uses:

Product Description: Laromer® LR 8986 is a modified aromatic epoxy acrylate oligomer characterized by its low viscosity, low yellowing, good flexibility, and excellent chemical & scratch resistance. It can be used in formulations for electron beam or UV curable printing inks and coatings, particularly for wood, wood products, plastics, and paper applications.

Key Features & Benefits:

• Low viscosity
• Low yellowing
• Good flexibility
• Excellent chemical & scratch resistance

Chemical Composition: Modified aromatic epoxy acrylate

Typical Properties:

• Appearance: Low- to medium-viscous liquid
• Acid value (EN ISO 3682): ≤ 5 mg KOH/g
• Viscosity at 23°C (ISO 3219 A): 3,000 – 6,000 cps
• Iodine color number (DIN 6162): ≤ 5
• Density (ISO 2811-3): ~ 1.160 g/cm3
• Flash point (DIN EN ISO 2719): > 100°C (212°F)

Applications: Laromer® LR 8986 can be used alone or in combination with other unsaturated acrylate oligomers to formulate printing inks and coatings for various applications, including:

• Printing inks for flexographic, gravure, lithographic, digital, or silk-screen applications
• Overprint varnishes for commercial, publication, or packaging applications
• Interior/exterior general industrial metal coating applications
• Interior/exterior wood coatings for floor, furniture, or millwork applications

Processing: Laromer® LR 8986 can be further thinned for processing with low volatile monomers or low viscosity polyether acrylates. The selection of monomers affects the properties of the cured ink or coating. Photoinitiators such as α-hydroxy ketone, benzophenone, acyl phosphine oxide, and blends thereof are used for photocuring.
