  • Develop and optimize water-based coating and release systems to meet performance and customer requirements.
  • Formulate and evaluate polymers, binders, surfactants, crosslinkers, rheology modifiers, and specialty additives.
  • Design and execute laboratory testing for adhesion, film formation, surface properties, stability, miscibility, crosslinking, rheology, and release performance.
  • Apply polymer chemistry, surface chemistry, rheology, dispersion, emulsion, and formulation principles to solve technical challenges.
  • Replicate customer and manufacturing processes in the laboratory to predict application and field performance.
  • Support customer trials, industrial evaluations, troubleshooting, scale-up, and plant trials.
  • Collaborate with R&D, manufacturing, quality, technical service, sales, and customers.
  • Maintain clear documentation of formulations, experiments, test results, conclusions, and recommendations.
  • Support new product development, raw material evaluations, continuous improvement, and scale-up activities.

Required Qualifications

  • Bachelor’s degree in Chemistry, Polymer Science, Materials Science, Chemical Engineering, or a related discipline.
  • 8–10 years of formulation experience in coatings, paints, adhesives, or related specialty chemical industries.
  • Demonstrated experience developing and testing water-based coatings and adhesives.
  • Strong working knowledge of polymer chemistry, surface chemistry, rheology, emulsions, dispersions, and aqueous formulation.
  • Hands-on laboratory experience with formulation development, coating testing, data analysis, and troubleshooting.
  • Ability to work safely with chemicals, laboratory equipment, and coating application methods.
  • Strong communication, documentation, problem-solving, and cross-functional collaboration skills.
