Flow Control Additives for Aqueous Wood Coatings

Flow Control Additives for Aqueous Wood Coatings | Uniform Application Without Runs

Flow control additives for aqueous wood coatings that improve spreading, sag resistance, and surface consistency across application methods.

Aqueous wood coatings require controlled flow behavior to avoid runs, edge build-up, and uneven film thickness. Poor flow control often leads to visible defects that reduce product value and increase rejection rates.

Mineral-based flow control additives improve rheology by increasing yield stress and structural recovery rather than simply increasing viscosity. This allows coatings to flow smoothly during application and quickly regain structure afterward, preventing sagging on vertical or detailed wood surfaces.

These additives are widely used in furniture coatings, panel finishes, and interior wood systems where appearance and repeatability matter.

FAQ  – Flow Control Additives for Aqueous Wood Coatings

What causes flow problems in aqueous wood coatings?
Insufficient structural recovery after shear.

How do mineral additives improve flow control?
They balance flow under shear with structure at rest.

Are they suitable for spray systems?
Yes, they perform well under high shear.

Do they improve surface smoothness?
Yes, they help coatings level more evenly.

Are they sensitive to formulation changes?
They are less sensitive than polymer-based additives.

Are they compatible with water-based sealers?
Yes, they integrate well with aqueous systems.
