Bostik PES 594V Ultra Flow Copolyester Hot Melt for PBT Bonding

Bostik PES 594V Copolyester Glue for Flexible Coating and PBT Lamination

Bostik PES 594V is a high-performance thermoplastic copolyester adhesive designed for flexible coatings and challenging bonding applications. With an ultra-high melt flow rate and low viscosity, PES 594V delivers fast, uniform coverage in high-speed production systems. Its compatibility with PBT (polybutylene terephthalate) makes it ideal for use in advanced textiles, technical films, and engineered composites. Supplied in pellet form, PES 594V supports efficient lamination and coating performance under demanding thermal conditions.
