Mr. Hirsch is a Senior Development Scientist and Principal Consultant at M&M Hirsch & Associates. Throughout his career, he has formulated architectural, industrial, military, and specialty coatings. He has developed applications and methodologies for sol-gel coatings, earned his Green Belt in MAIC Six Sigma, and trained for MAIC Black Belt. He has applied MAIC methodology to the CTR for several laboratory and manufacturing processes in coatings, resulting in substantial savings. Mr. Hirsch has also successfully facilitated numerous ideation teams, both within his area of expertise and outside of it, including cross-functional and cross-business groups.

Prior to his current position, he worked at GE Energy (2008-2011) in the Simulation group, writing proposals to published specifications for training simulators for both fossil and nuclear power plants. At Luna Innovations (2004-2008), he was a Developmental Scientist in the Advanced Materials group. At Dow Chemical (1995-2004), he was the applications and development manager in Core R&D in the Coatings & Functional Polymers Group. He also managed the TS&D group for coatings while at Dow (1995-1999) and held positions at Rhodia as Laboratory Manager, Latex & Specialty Polymers (1989-1995) and Development Chemist, Exterior Latex Paints at Benjamin Moore & Co. (1979-1982).

Mr. Hirsch consults for organizations, providing mentoring, coaching, leadership training, and facilitation of problem-solving teams.

Why should you view this course?

Foam in coatings and inks leads to longer production time, craters on dried film... so you use defoamers. Be wise and avoid all the well-known undesired side effects associated with this practice: adhesion, colorant rub-up… Join this course and you will:

  1. Better prevent & troubleshoot foaming by identifying what is promoting foam stabilization: Gibbs effect, surface viscosity, cohesive strength...

  2. Screen defoamers more efficiently with fast & easy tests to simulate foam generation during manufacturing, filling, application... for paints, inks, adhesives, and construction products.

  3. Optimize benefits delivered by your defoamers: avoid over dosage, loss of efficiency, film defects... You will end up with simpler and cheaper formulations!

Who should join this course?
  • Experienced coatings, inks, and colorants formulators involved in formulation optimization and troubleshooting.

  • This course is suitable for intermediate level proficiency
