Polysiloxane Defoamer for NC and PU Wood Coatings
CAS Number: 8050-81-5
Polysiloxane-based defoamer formulated specifically for NC lacquers, PU coatings, and UV wood finishing systems eliminates micro-bubbles and macro-foam formed during high-speed spray or roller application without causing surface defects. It is compatible with solventborne and UV systems and does not impair intercoat adhesion or gloss. Effective in preventing pinholes in high-build wood sealer and filler coats.
