Introduction
WL-UV518 is a novel solvent-free, hexafunctional waterborne
polyurethane acrylate
oligomer specifically designed for hard coatings. This product
features extremely fast curing
speed and delivers cured films with excellent scratch resistance.
Its low viscosity makes it
suitable as a main component for water-based coatings applied via
spraying or curtain
coating methods. WL-UV518 can be blended with other waterborne UV
resins to enhance
either the solid content or coating hardness of the final
formulation.

Performance Features
Low viscosity
The UV/EB curing coating prepared based on WL-UV518 has the
following
characteristics:
High solid content
- Fast curing speed
- Extremely high surface hardness and scratch resistance
- Good stain resistance
- It can be directly coated on various plastic substrates
The true performance of the UV/EB cured product also depends on
other components in
the formula, such as reactive diluents, additives and
photoinitiators, as well as the curing
conditions.
This material is complied according to our existing technology and
