EBECRYL® 140

EBECRYL® 140 is a ditrimethylolpropane tetraacrylate, which is a reactive diluent used in UV and EB curable coatings and inks. Here's a breakdown of its features, applications, and precautions:

Introduction:

• EBECRYL® 140 is a reactive diluent that exhibits good cure response and light color.
• It can significantly improve cure response, hardness, and resistance to chemical, scratch, and abrasion when added to UV and EB curable coatings and inks.

Performance Highlights:

• Light color
• Good cure response
• Low irritancy
• Flexibility while retaining hardness
• High abrasion resistance
• Good chemical resistance

Suggested Applications:

• Suitable for lithographic offset inks and overprint varnishes
• Compatible with a wide range of acrylated resins used in UV/EB curing applications
• Effective levels typically range from 10% to 30% depending on the application
