The performance of paints, inks, and other coatings is heavily dependent on the quality and uniformity of their formulation. At NINGBO INNO PHARMCHEM CO.,LTD., we are committed to providing specialty chemicals that elevate the capabilities of these formulations. Our OT75 surfactant plays a critical role in achieving superior coatings by enhancing pigment dispersion and improving flow characteristics.

Coatings are complex mixtures that often involve pigments, binders, solvents, and various additives. For a coating to perform optimally – providing good coverage, adhesion, and a smooth finish – all its components must be well-dispersed and interact appropriately. This is where wetting agents, or surfactants, like OT75 become indispensable. They are designed to reduce the surface tension of liquids, facilitating better interaction between different components and surfaces.

OT75, an advanced anionic surfactant, excels in several key areas relevant to coating formulations:

1. Superior Pigment Dispersion: Pigments are solid particles that need to be evenly distributed within the coating base to achieve consistent color and opacity. Wetting agents like OT75 help the liquid phase of the coating to effectively wet the surface of these pigment particles. This wetting action prevents the pigments from clumping together (agglomeration) and ensures they remain finely dispersed. A well-dispersed pigment system leads to better color development, improved hiding power, and a more stable final coating. This makes OT75 a highly effective wetting agent for coatings.

2. Enhanced Flow and Leveling: The ability of a coating to flow smoothly and spread evenly across a substrate is crucial for achieving a professional finish and preventing defects like brush marks or orange peel. OT75's property of reducing surface tension allows the coating to spread more readily, leading to improved flow and leveling. This characteristic makes it valuable as a flow and solvent agent in many coating applications.

3. Improved Substrate Wetting and Adhesion: Beyond the internal formulation, a coating must also wet the surface it is applied to. OT75's inherent wetting capabilities ensure that the liquid coating spreads properly on various substrates, promoting better adhesion and preventing issues like crawling or beading. This improved substrate interaction is vital for the durability and longevity of the coating.

4. Emulsification in Water-Based Systems: Many modern coatings are water-based, requiring effective emulsifiers to keep binders and other hydrophobic components dispersed in the aqueous medium. OT75's emulsifying properties contribute to the stability of these water-based systems, ensuring that the coating remains homogeneous and easy to apply.

The consistent performance and versatility of OT75 make it a sought-after component for formulators aiming to create high-quality paints, inks, and other surface treatments. Its ability to tackle multiple challenges within a single formulation highlights its value as a specialty chemical additive.
