Bostik PA 5420 Steam Resistant Fabric & Apparel Copolyamide Hot Melt

Bostik PA 5420 Copolyamide Adhesive for Steam-Resistant Clothing, Apparel, and Fabric Lamination

Bostik PA 5420 is a thermoplastic copolyamide adhesive designed for clothing, apparel, and fabric lamination where high steam and wash resistance is essential. Offered in powder and pellet form, it withstands laundering up to 194°F (90°C) and delivers excellent dry cleaning durability. Its thermal stability and controlled flow make it especially effective for structured garments, steam-pressable interlinings, and heat-resistant laminates.
