Adhesives and Sealants Formulations with Polyamide (PA) Resins

Polyamides appear as amber to clear materials that form tough, resilient bonds. Their functionality relies on hydrogen bonding and molecular entanglement that creates strong cohesive strength and excellent adhesion to many substrates. Notable features include outstanding toughness, good chemical resistance, and excellent thermal stability. Polyamide are ideal for automotive components, footwear assembly, and textile bonding where substrates may expand or contract under varying conditions. 

The industry is seeing increased development of bio-based polyamides derived from renewable resources. Sub-types include thermoplastic polyamides with hot-melt application properties, reactive polyamides, co-polymerized polyamides, and specialty grades like transparent polyamides.
