Replacing Solvents in Industrial Coatings with Solubility Parameters

This is a Past Course

Recorded on Nov 6, 2019

Easily find greener alternatives to your existing solvents and meet the regulatory & safety requirements (low toxicity, VOC, flammability...) faster.

Leading expert, François Magnin will share science-based predictive method using Hansen Solubility Parameters (HSP) for quicker solvent selection. HSP calculation methods, examples and the key factors to consider (solubility volume, solvent evaporation profile…) will be discussed in detail.

Why should you view this course?

Growing concerns (odor, toxicity...) around ecotoxicological profiles of many commonly used solvents in industrial coatings, cost pressure, and the advent of newer resins require you to find and work with new & greener solvents. Yet, solvents impact many key properties in your industrial coatings and no solvent will ever appear as an obvious alternative.

Guess work can help if you have plenty of time. Join this course and leverage proven shortcuts! No dark art here, it is based on predictive scientific models.

  • Shorten time spent on trial & error when finalizing the alternative solvents based on a smart mapping of Hansen Solubility Parameters.

  • Replace existing solvents and/or blends to align with your needs (cost considerations, new resin chemistries…).

  • Solve film defects by using HSP monitoring when dealing with evaporation.

  • Meet both regulation & safety requirements (low toxicity, VOC…) with very practical tips for solvent replacement.

Who should view this course?

Solvent-based industrial coatings formulators involved in formulation optimization and troubleshooting must opt for this course.

Course Outline

  1. What drives need for new solvents and reformulation?
    • New formulations
    • New regulations
    • Other factors (cost, availability…)

  2. Factors affecting the choice of solvent
    • Solubility/compatibility
    • Viscosity
    • How solvents help in obtaining high-quality coating?

  3. How to find greener solvents faster with Hansen Solubility Parameters (HSP)?
    • Understanding the HSP model & its parameters (dispersion forces, polarity dipole-dipole interaction, hydrogen bonding)
    • How to use them?
    • How to measure HSP?
    • Calculation of the HSP of a blend
