LAROMER LR 8863
LAROMER LR 8863
LAROMER© LR 8863 is a polyther-modified acrylate oligomer for the formulation of energy curable printing inks and coatings for wood, wood products, paper, and plastic applications. It is used as a reactive diluent in higher viscosity resins such as polyester acrylate, epoxy acrylates, or urethane acrylates.
This product is recommended for use in energy curable flexographic, screen, and offset inks and overprint varnishes. It provides good pigment wetting characteristics and flexibility without sacrificing cure rate. Cured inks and overprint varnishes formulated with LAROMERÂ LR 8863 provide good resistance properties and hardness.
LAROMER LR 8863 is recommended for applications such as:
- Pigment dispersions
- Printing inks for flexographic, gravure, lithographic, digital, or silk-screen applications
- Overprint varnishes for commercial or publication applications
- Interior/exterior general industrial metal coating applications
- Interior/exterior plastic components coating applications
- Interior/exterior wood coatings for floor, furniture, or millwork applications
Features & Benefits
- Good adhesion
- Good flexibility while maintaining high hardness
- Fast cure speed
- Good pigment wetting
- Low viscosity and excellent diluent
