Additives are added in small quantity but they create a large impact on the appearance and performance of the coating. For instance, Polyetheramine T5000 is a superior coating additive which provides stronger cross linking. It is thus used for imparting resistance to corrosion in epoxy-polyurethane system.
Similarly, there are other additives used for their distinct functions. These are generally of the following types:
· Wetting and dispersing additives: Wetting agents prevent the wetting of solids and dispersing agents prevent flocculation of particles because of steric effects.
· Flow and leveling additives: Polyether modified siloxanes and perfluro modified surface additives are used to decrease surface tension. They prevent thermal degradation and improve compatibility.
· Defoamers and deaeraters: These are anti-foaming agents. Polydimethylsiloxanes, certain alcohols, glycols are generally used as deforming agents. They destroy the air bubbles and thus breakdown the surface foam. These chemicals generally have low viscosity.
· Rheology modifiers: The modifiers prevent sedimentation of paint pigments. They are used to control the fluidity of paints. Jeffamine D230 is an agent generally used for this purpose because of its low viscosity.
· Driers and Catalysts: Driers are generally used to harden the paint and enhance its lubricating property. They also decrease brittleness. These agents are generally used for improving the quality of varnishes, paints and printing ink.
There are various companies which provide such coating for varied purposes. IRO Coating additive Co., Ltd. is one such company which provides various additives that can enhance the properties of a material. These additives are used as emulsions along with the paints for making the surface of the infrastructure scratch resistant.
