Importance of Additives in Paint

In paint formulation, there are several important ingredients to consider. These include Micaceous iron oxide, Rheology modifiers, Wetting agents, and hydrophobic surfactants. These components enhance the viscosity of paint and improve its appearance, durability, and flow. Listed below are some of the additives that improve paint’s performance. If you’re unsure of which additive to choose, read on to learn more.

Rheology modifiers

Rheology modifiers

Rheology modifiers, also known as viscosity modifiers, are chemicals added to liquid products to impart specific rheological properties. These chemicals are used to improve the efficiency of the final product, increase flow properties, decrease sedimentation of solid substances, and enhance sag resistance.

Micaceous iron oxide

Micaceous iron oxide (MIO) is a common additive in paints. This anti-corrosive additive has been around for over a hundred years. It is the most effective barrier pigment, able to protect structural steel. This material is used more frequently in Europe than in the United States. Famous structures coated with MIO include the Eiffel Tower in Paris, Big Ben in London, the Sidney Harbor Bridge, and the Golden Gate Bridge.

Wetting agents

Wetting Agents are substances used in paints to help increase the tinting strength and compatibility of pigments. A range of wetting agents was evaluated by Clariant for use in waterborne emulsion paints, solvent-borne alkyd lacquers, and low-PVC emulsion paints. Their efficacy is largely dependent on how well they can overcome the hydrophobicity of pigments.

Hydrophobic surfactants

The role of hydrophobic surfactants in paint comes from their ability to attract water molecules to the surface of the paint. This is a major factor in creating a high-shine finish on painted surfaces. Surfactants are also used in detergents, soaps, and household cleaners. They can be used in a variety of products and are useful for deinking recycled paper.

Dispersing agents

Dispersing agents are components of paints that help maintain the dispersion properties of pigment particles over time. They prevent pigment particles from flocculating, sedimenting, or changing viscosity. The choice of dispersant is important for color development and long-term shelf-life. Synthetic latex is an example of a dispersion, formed by polymerizing monomers. Radical primers stabilize the polymerization process, resulting in dispersed particles.
