Course Description

Go beyond traditional PUR-based reactive hot melt adhesives to match today’s performance requirements (increased shelf life, pot life; difficult to bond substrates, a wider range of service temperatures, reduced free isocyanates (NCO)...).

In this simulated live, Edward Petrie will review newer base polymer chemistries (hybrids, polyolefins, SBC, and their impact on properties...) & the latest test methods. With quick-to-apply material selection & formulation guidance, you can immediately implement strategies to enhance cross-linking speed & product performance.

Edward Petrie has been active in the adhesives industry for over 35 years, both in the formulation and end-use sides. He has a BS (Chemical Engineering) and MS (Polymer Science) degrees from Carnegie Mellon University and an MBA from Duquesne University.

Throughout his industrial career, Mr. Petrie has been employed by two major global corporations ABB and Westinghouse as an internal consultant in adhesives and polymeric materials. In both corporations, he was part of the Central Research Laboratories and assisted all of the divisions within the organization.

His expertise includes material and process selection, testing, formulating, substrate preparation, and quality control, with emphasis on the end-user application and performance requirements. Applications include structural and non-structural joining of all materials. Mr. Petrie is also an expert in joining polymeric materials by all methods, including mechanical fastening, self-fastening, and heat and solvent welding.

Mr. Petrie has authored over 100 papers on adhesives as well as the popular Handbook of Adhesives and Sealants (McGraw-Hill, October 2000) and Plastic Materials and Processes – A Concise Encyclopedia (John Wiley & Sons, August 2003). He has also given seminars and adhesives and adhesion to corporations, universities, and government organizations.

Mr. Petrie is an independent consultant and sole proprietor of EMP Solutions. He is also a Technical Advisor and Consultant to adhesives.specialchem.com, an online service platform dedicated entirely to adhesives and sealants.

Why should you view this course?

Traditional PUR-based reactive hot melt adhesives with novel properties (like - high bond strength & high-heat resistance) have been a popular technology till now. But what has evolved since then are its performance requirements with respect to high-end applications (auto, electronics, and packaging).

While it’s relatively easier to achieve basic properties, enabling advanced RHMA is complex and often application specific. So, despite spending your precious time on trial & error, join this course and:

  1. Review newer base polymer chemistries (hybrids, polyolefins, SBC, and their impact on properties...) with quick-to-apply material selection & formulation guidance.

  2. Know about the key attention points catering to performance requirements (increased shelf life, pot life; reduced free isocyanates (NCO)...) for reactive hot melts.

  3. Upgrade your formulation expertise by leveraging the latest material, tech, and testing advances & knowing their impact on final performance, crosslinking speed/crosslinking rate.
