Formulating Advanced Reactive Hot Melt Adhesives

On-Demand Course

Recorded on Dec 8, 2022

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)...).

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.

Why should you view this course?

Traditional PUR-based reactive hot melt adhesives with novel properties (like - high bond strength & high-heat resistance) has been a popular tech till now. But what has evolved since then are its performance requirements w.r.t 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:

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

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

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