R&D Process

At KOCH and KOONE, new product development and quality stabilization are our highest priorities in building trust with our customers. We are committed to fulfilling our promise of delivering the highest quality products through continuous research and innovation.

New Product Development

Research and develop new products by combining coating technologies, inorganic minerals, and hybrid materials tailored to the needs of various industries.

Product Quality Control

Verify product quality throughout the manufacturing process. Fundamental tests, including particle size and whiteness measurements, are conducted during production to minimize defects and ensure consistent product quality.

Product Quality Certification

Manage quality-related documentation such as TDS (Technical Data Sheet) and COA (Certificate of Analysis), while maintaining patents and ISO quality certifications.

Test method
  • Particle Size Distribution

    Measure particle size and particle size distribution to verify product uniformity.

  • Whiteness

    Measure whiteness and color difference to evaluate product color quality.

  • Moisture Content

    Measure moisture content to ensure product quality and stability.

  • Loss on Ignition (LOI)

    Evaluate Loss on Ignition (LOI) characteristics by measuring weight loss after heating the sample at a specified temperature.

  • Oil Absorption

    Measure oil absorption to evaluate surface characteristics and dispersion properties.

  • Bulk Density

    Measure the bulk density of the powder by weighing the product after filling a standardized container.

  • pH Measurement

    Measure pH to verify the product's chemical properties and quality stability.

  • Sieve Test

    Measure the content of coarse particles using standardized sieves.

  • XRF

    Perform qualitative and quantitative analysis of elemental composition using X-ray Fluorescence (XRF) analysis.

  • SEM

    Observe particle morphology and surface characteristics using Scanning Electron Microscopy (SEM).
