Sealants and Caulks: Formulation & Plasticizer Selection Strategies

On-Demand Course

Recorded on Dec 2, 2021

Achieve desired properties (flexibility, better low-temperature, adhesion…) in sealants and caulks formulation by choosing the right plasticizers & understanding how to balance the raw materials they work well with.

Leading expert, William D Arendt will help you gain an in-depth understanding of the various classes of sealants (polysulfide, plastisol…) and caulks (latex, waterborne...). He will also share a systematic selection/formulation strategy and testing criteria (ASTM, ISO…) to help you develop successful formulations.

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 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, viscocity...).

  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…).
