When thinking about paint, the first thing that often comes to mind is color. However, the desired quality of paint cannot be achieved through color alone. Pigments must be evenly dispersed, the paint must be smoothly applied to the surface, and it must dry properly without stains or clumps. Only then can a uniform color and clean finish be achieved.

To make this possible, a material is needed to help the various components of paint, such as pigments and resins, blend well together and create the right viscosity for coating. Today, we take a closer look at IPA (Isopropyl Alcohol), a solvent used across a wide range of industries, from paints and inks to advanced electronic materials manufacturing processes.

IPA: A Solvent with Excellent Solubility and Rapid Evaporation

IPA (Isopropyl Alcohol) is a colorless, volatile liquid with excellent solvent properties. It mixeswell with a wide range of substances, including water, hydrocarbon oils and oxygenated organic solvents, helping different components blend together uniformly.

A solvent is a liquid that dissolves or disperses other substances to make them suitable for use. It can be seen as a medium that helps each raw material perform its intended function during product manufacturing. Based on its excellent solvent properties, IPA is widely used in fields such as coatings, inks, cleaning agents and chemical reagent materials.

High evaporative properties are also an important characteristic of IPA. Because it evaporates quickly after performing its required function as a solvent, it is suitable for processes that require not only dissolution and cleaning but also drying. IPA contributes across a broad range of steps, from helping different components mix evenly to finishing a surface after processing.

The Hidden Helper Behind a Better Paint Finish

Coatings and inks are composed of pigments that create color, resins that form a film on the surface, and various components that adjust viscosity and functionality. These components must be mixed evenly for color to be expressed uniformly and for coating or printing results to remain consistent.

Here, IPA helps pigments and resins dissolve well and plays a role in creating the right viscosity for work. Viscosity affects how well paint applies to a surface and whether it can be coated evenly without running or clumping. IPA helps each component work together, supporting smooth and stable coating and printing.

After coating or printing is complete, the solvent evaporates and the surface dries. With its high evaporative properties, IPA also contributes to the drying and finishing process. In this sense, IPA is a hidden helper that performs its role behind visible color and gloss, then disappears.

IPA’s Expanding Role in Cleaning and Precision Processes

IPA is used not only in coatings and inks. Its excellent solvent properties and high evaporative properties are also strengths in cleaning processes, where contaminants must be removed without leaving stains or residue on the surface.

In particular, in electronic materials manufacturing processes for semiconductors and LCDs, even microscopic contamination or impurities that are invisible to the eye can affect product quality. For this reason, a much higher level of cleanliness is required than in general cleaning processes.

In these precision processes, high-purity IPA is used as a cleaning agent for electronic materials. After wafer cleaning, it helps dry the surface and reduce staining, supporting stable processes and quality. This is why IPA is important in electronic materials manufacturing sites, where a clean surface must be maintained while the material evaporates quickly.

In addition, IPA is used in disinfectant products based on its sterilizing properties and is also used in chemical reagent materials and pharmaceuticals. A single material can perform different functions depending on the purpose and process of each industry.

LG Chem’s IPA, Designed with Both Quality and Sustainability in Mind

LG Chem is the only IPA producer in Korea that produces both acetone-based IPA and propylene-based IPA. With these different production bases, LG Chem has secured the competitiveness to supply IPA stably according to the needs of different industries.

LG Chem also produces HP-IPA (High Purity IPA) for precision processes that require a high level of cleanliness. HP-IPA is used in electronic materials manufacturing processes for semiconductors and LCDs, where even small impurities can affect quality. It is a product suitable for advanced industries where material purity and quality stability are important.

Bio-Circular Balanced IPA, which considers sustainability, is also part of LG Chem’s IPA product lineup. It uses bio-based renewable raw materials derived from sources such as used cooking oil and plant-based byproducts together with conventional fossil-based raw materials. By doing so, it helps reduce the use of fossil-based raw materials and contributes to lower carbon emissions while maintaining the physical properties of conventional products.

LG Chem’s Bio-Circular Balanced IPA obtained ISCC PLUS certification in 2021. ISCC PLUS is an international certification that verifies the use of sustainable raw materials and supply chain traceability. This certification is meaningful in that it recognizes the raw material management system across the overall product production process.

From the uniform finish of paints and printing inks to precision cleaning in semiconductor manufacturing processes, IPA supports the quality of products and processes in places that are not always visible. Although the functions required by each industry may differ, IPA’s ability to dissolve well and evaporate quickly serves as a foundation that connects various products and technologies.

Based on its stable IPA production capabilities, high-purity products and Bio-Circular Balanced product lineup, LG Chem provides solvent material solutions tailored to the needs of different industries.
