Polyamide additive technology has become a market reference in order to achieve the required rheological properties in many systems, including adhesives and sealants.

In parallel, silyl-terminated-polymer technology is increasing its market share, with high growth rates in many sectors such as construction and transportation. Additionally, needs for high-tack systems are increasing, as adhesives replace mechanical fasteners and, more generally, to enhance the end properties in application areas when specifically needed.

For these applications, polyamide additives represent a tool of prime interest to achieve a suitable rheological profile with a good compromise between high early grab and enhanced workability.

A brief introduction of the polyamide technology, in terms of chemistry and physical properties, will be shared. The paper will then focus on practical examples adapted to STP based high-tack formulations, showing different methods of characterisation and the performance of various additives regarding these properties.

Finally, the performance of a newly developed polyamide product will be examined, highlighting the differentiation it brings to formulators.
