Soya lecithin is a natural ingredient derived from soybean extract and contains phospholipid compounds. In industry, it is commonly used as an additive to help improve the stability and blending of various components.

In coatings and paints, soya lecithin is not a primary ingredient, but it plays an important role in improving the quality of the final product.

Functions of Soya Lecithin in Paint

1.	Dispersing Agent (Pigment Dispersant)
	Soya lecithin helps pigment particles disperse evenly throughout the paint mixture. Benefits:
	More consistent color Reduces agglomeration Improves finishing quality

2.	Emulsifier
	As an emulsifier, soya lecithin helps combine oil- and water-based components and prevents them from separating. This function is particularly important for:
	Water-based paints Environmentally friendly coatings

3.	Wetting Agent
	Soya lecithin helps the paint wet the surface more easily, thereby:
	Improves adhesion Reduces defects such as “spots” or uncovered areas

4.	Anti-Settling Agent
	Prevents heavy particles in the paint from settling during storage, thereby:
	Keeps the paint homogeneous Reduces the need for excessive stirring

Forms of Soya Lecithin for the Paint Industry

In coating applications, soya lecithin is typically used in the following forms:

Liquid (viscous liquid) → most commonly used
Dark brown / amber in color
Easily mixed with resins and solvents

Granule or powder forms are rarely used directly because they must be reprocessed first.
