Product Introduction:
Styrene Acrylic Resin have excellent mechanical performance and
weatherability, be widely used in inks and coatings for alkyd
solubility. Select different monomer ratios, the acrylic resin of
various different performance can be prepared. The Acrylic resin in
solvent inks, which is designed to as nitrocellulose replacement
and pigment dispersion, it can be made of ink. WL-AS302 can be
prepared for white inks of high solids, clearance, and high
coverage.
Characteristic and Benefits:
- Provides an outstanding combination of hardness, flexibility,
- Increased formulation freedom.
- Easily dispersability in solvents or solvent blends suitable for
flexo or gravure ink applications.
- Enables high solids surface printing and lamination applications.
- Good adhesion, good pigment dispersion
- High purity, good compatibility with alkyd resins
Physical Characteristics:
These properties are typical values but do not constitute
specifications.
