PSA adhesives

PSA adhesives are ready-to-use, tacky adhesives that form a strong bond when light pressure is applied, without the need for heat, water, or solvents. They are valued for their instant adhesion, clean application, and versatility, making them ideal for a wide range of industrial and commercial applications.

IWG’s PSA adhesives are formulated for consistent performance on diverse substrates, including paper, plastics, films, foils, fabrics, and metals. Commonly used in labeling, packaging, laminating, protective films, and signage, PSA adhesives provide durable, flexible, and long-lasting bonding while maintaining excellent resistance to temperature, aging, and environmental conditions. Designed for manufacturers and converters, PSA adhesives deliver high efficiency, reliability, and strong initial tack for automated and manual production processes alike.

FAQ
<p><strong>Q1: What is the difference between PSA and hot melt adhesives?</strong></p><p>PSA adhesives bond instantly under pressure and remain permanently tacky, while hot melt adhesives require melting and solidification. PSAs are preferred for nonwoven and paper applications that need flexibility and re-stick properties.</p><p><br/></p><p><strong>Q2: Are PSA adhesives safe for hygiene and skin-contact products?</strong></p><p>Yes. IWG’s PSA adhesives are odor-free, non-toxic, and dermatologically tested, making them suitable for baby diapers and hygiene product manufacturing.</p><p><br/></p><p><strong>Q3: How can I optimize PSA adhesive performance on high-speed lines?</strong></p><p>Maintain consistent coating temperature and pressure, ensure clean substrates, and select a PSA grade that matches your substrate surface energy and coating speed. IWG engineers can recommend ideal viscosity and tack levels for your line.</p><p><br/></p>
