Glossary

Anti-floating, anti-flooding agent Anti-floating, anti-flooding agents An agent that hinders the vertical and horizontal separation of pigments with different densities and surface activities Anti-settling agent Anti-settling agents An agent preventing the particles in a paint composition to coagulate and to form a sediment Anti-skinning agent Anti-skinning agents An agent that counteracts the tendency of drier containing paints to form an insoluble surface skin on contact with atmospheric oxygen and promotes uniform drying and hinders wrinkling; Suppresses skin formation on air-drying alkyd paints in the can, particularly after the can has been opened. Dispersion agent Dispersion agents An agent that counteracts the settling tendency of pigments, especially those with high densities, also anti-settling agent Gloss-reducing agent Gloss-reducing agents Matting or flattening agent Levelling agent Levelling agents An agent that promotes the formation of smooth, uniform coating films from uneven, patterned layers of wet paint Wetting agent Wetting agents An agent that promotes the dispersion of the pigments in the binders and counteracts the flocculation tendency of particles that are insufficiently wetted
