According to the physical and chemical nature of the coating, the coating additives can be divided into several categories, such as solvent-based paint additives, water-based paint additives and powder coating additives. A more practical classification is according to coating functionality, performance and composition. Water-based paint additives can be divided into the following categories.

Flatting agent: include wetting and flatting agent and surface tension reducing agent, smooth flatting agent, Silicone flatting agent, acrylic flatting agent, Polyether siloxane flatting agent.

Wetting agent: including substrate material wetting agent and pigment filler wetting agent, anti-foam substrate wetting agent, non-ionic wetting agent.

Dispersing agent: wetting dispersing agent and pigment dispersing carrier, controlled flocculation wetting dispersing agent, flocculating wetting dispersing agent,

Rheological additives: including thickening agent, agent, agent construction solution of variable flow and leveling agent, cellulose thickener, thickening agent, alkali swelling polyurethane associative thickener, according to the characteristics of Newton for the behavior of pseudoplastic thickener, associative thickener etc.

Defoaming agent: including defoaming agent, antifoaming agent, foam breaking agent, water based silicone defoaming agent, mineral oil defoamer, fluorine silicone defoaming agent, silicone defoaming agent, silicon free defoamer, polymeric defoamer.

Film forming agent: plasticizer, polymerization agent, cosolvent, cosolvent.

Preservatives: including tank preservatives, fungicides and algaecide coating.

Matting agent: extinction powder, wax emulsion, wax powder, silica matting powder.

Wax and wax emulsion: natural wax, synthetic wax, plant wax, animal wax, wax, polymer Brazil palm wax, beeswax, paraffin wax, wax etc..

PH regulator: PH regulator comprising a multifunctional effect.

Curing agent: polyisocyanate crosslinking agent, aziridine compound crosslinking agent, crosslinking agent, epoxy siloxane crosslinking agent, crosslinking agent, carbon two imine metal ion oxidation crosslinking agent, crosslinking agent, amine crosslinked epoxy emulsion, melamine resin crosslinking agent and modified isocyanate crosslinking agent.

Corrosion inhibitor and corrosion inhibitor, anti rust agent, anti tank steel rust agent, corrosion inhibitor, organic inorganic mixed corrosion inhibitor, corrosion inhibitor.

Drying agent, anti skinning agent and catalyst.

Antioxidant and light stabilizer.

Special effects additives: including sliding, wear resistance, scratch resistance, hard, soft, anti adhesion, hydrophobic, anti graffiti, improve adhesion, whitening and other additives, hydrophobic agent.

Some additives of water - based paint additives have many functions at the same time. For example, the wetting agent has defoaming effect, smooth wetting effect, and the wax powder has extinction effect.

In the future, the development of paint additives is still aimed at high efficiency, long term, multi use, environmental protection and safety. In particular, water-based paint additives, take the green environmental protection as the leading, only to achieve no VOC, no APEO, can make water-based coating be green paint.
