Ink Defoamer
CAS Number: 8042-47-5
A mineral-oil-based defoamer specifically formulated to suppress and destroy foam and micro-foam in water-based and solvent-based ink systems. Its unique hydrophobic silica particle blend rapidly destabilizes foam lamellae, ensuring smooth ink transfer and defect-free print surfaces. Low effective dosage minimizes impact on gloss and adhesion.
