Additives is in addition to the main film forming material, filler, solvent, a component added to the coating, can make a specific performance of the coating or film play a significant role in the improvement of the substance. The amount in the coating formula is very small, mainly a variety of inorganic compounds and organic compounds, including polymer and so on.

Coating additives are classified according to their functions in processing, storage, construction and film forming process.

Improve the performance of coating production process: wetting agent, dispersant, emulsifier, defoamer, etc.

Improve the storage performance and transportation performance of coating: anti-sedimentation agent, anti-crust agent, preservative, freeze-thaw stabilizer, etc.

Improve coating construction performance: thixotropic agent, anti - current hanging agent, resistance regulator, etc.

Improve the curing film forming performance of coating: drying agent, curing accelerator, photosensitizing agent, photoinitiator, film forming agent, etc.

To prevent the performance of paint film: anti-flow hanging agent, leveling agent, floating color flower prevention agent, adhesion agent, thickening agent, etc.

Give paint a special performance: UV absorbent, light stabilizer, flame retardant, antistatic agent, mildew, etc.
