WL-AS302 Weatherability Solid Acrylic Resin Alkyd Solubility For Ink
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
