Course Description

Achieve the perfect balance of flexibility, adhesion, and low-temperature performance in your sealants and caulks. Learn how to select the right plasticizers – the secret ingredients that enhance flexibility – and ensure compatibility with your chosen polymers.


Join leading industry expert, William D Arendt who will provide a practical roadmap with formulation examples for successful sealants and caulk formulation. More importantly,


  • Master a systematic approach to selecting the right non phthalate plasticizers and formulating winning sealants.
  • Delve into the wide range of newer plasticizers and learn to get the best out of your specific sealants (polysulfide, plastisol…) and caulks (latex, waterborne...).
  • Learn how to evaluate plasticizer performance and navigate industry testing standards like ASTM and ISO.

Formulate high-performing sealants and caulks that meet your specific needs and industry standards.

Why should you view this course?

Different classes of sealants (polysulfide, plastisol) and caulks (latex, waterborne...) formulation require you to carefully select the right plasticizers. But, with increasing regulatory pressures on phthalates plasticizers and product discontinuations, it is challenging to pick one that fits all your application requirements (construction, aerospace, automotive, beverage cap seal...).

Additionally, the wide offering of newer plasticizers (non-phthalate, non-migrating...) makes the choice even tougher! Join this course and:

  1. Learn how to efficiently choose plasticizers by reviewing steps in the evaluation process (compatibility, efficiency, permanence, processability…) that factor in its optimal selection.

  2. Better analyze how raw materials (fillers, pigments, polymer…) interact in your formulation and optimize the balance between them to design a successful formulation.

  3. Gain strong knowledge about testing procedures to perform (ASTM, ISO comparisons...) to meet today’s performance demands (lower glass transition temperature, impact resistance, viscosity…).

  4. Understand clearly different classes of sealants (polysulfide, plastisol…) and caulks (latex, waterborne…) to make better decisions in your day-to-day work with the help of real-life examples (container closure seal, automotive seam seals…).

Who should join this course?

  • This course is for Technologists, R&D, Formulators, Raw material suppliers, Manufacturers, and End users in the sealants and caulks industry. However, technical management, production, and purchasing personnel can also benefit from it.
