Water Based IV
Aqueous Brilliance
Reliable aqueous coating with flawless finish
COAT ICON ® GW4 is a premium aqueous tablet coating system powered by PVA (polyvinyl alcohol) and soya lecithin, designed to deliver excellent adhesion, superior film toughness, and reliable moisture protection.
With its high surface definition and smooth flow around embossing, it ensures a flawless finish and prevents peeling, even on high-speed compression lines.
Why Use PVA (Polyvinyl Alcohol) for Tablet Coatings?
| Property | Benefit |
|---|---|
|
High Adhesion Strength |
Excellent binding to tablet core; resists flaking and peeling |
|
Tough & Flexible Film |
Resists cracking during compression, transportation, and handling |
|
Moisture Resistance |
Moderately hydrophobic—better barrier vs. HPMC |
|
Low Tackiness |
Smooth processing at high pan speeds |
|
Low Oxygen Permeability |
Good for oxidation-sensitive APIs |
|
Aqueous Compatibility |
Soluble in water — avoids organic solvents |
