Silyl Modified Polymers in Adhesives, Sealants & Coatings for High-performance & Safety

On-Demand Course

Recorded on Mar 7, 2024

Limit the use of isocyanates & switch to silane hybrid prepolymers vs PU in your adhesives, sealants, coatings by achieving a better balance of mechanical properties (strength, elongation, viscosity control…).

William D. Arendt will present a unified approach to explain the silane technology (silyl modified polymers, silane additives…) and moisture cure tech. He will share practical applications (construction sealants, PSA, roof coatings…) to enable better formulation design aligned with specifications (eliminating N=C=O group).

Why should you view this course?

Whether you formulate adhesives, sealants or coatings, one of the significant issues is to avoid unreacted N=C=O group in your polyurethane formulations. This is driving the transition to safer silane hybrid polymers but it is slow. Acting as roadblocks are other challenges that remain regarding balancing properties (strength, elongation, viscosity control, stability in use…).

Now, with incremental progress seen in silane additives (coupling agent, adhesion promoter, moisture scavenger…) & silyl terminated polymers, better formulation designs are possible! Join this course today to:

  1. Design high-performing, safer formulations with in-depth understanding of silanes (silyl modified polymers, silane additives…).

  2. Gain a better understanding of moisture cure technology and & how to implement it in your adhesive/coating systems.

  3. Learn how to achieve a good balance of mechanical properties (strength, controlled viscosity…) to boost the transition to safer silane hybrid polymers vs PU.

Who should view this course?

This course is useful for professionals in adhesive, sealant and coating industries including formulators, raw material suppliers looking to adopt silane hybrid tech or improve the balance of properties of silyl modified polymers
