Pyrosil

Are you struggling to bond low surface energy plastics like HDPE, PP, or PE? Many adhesives fail on these materials, creating weak bonds and costly rework. Pyrosil LSE surface treatment provides a proven solution.

Developed by SURA Instruments in Germany, Pyrosil has more than 30 years of success in boosting adhesion. Unlike standard flame treatment, this process chemically transforms the surface. It creates a nanometer-thin but dense SiO² silicate layer, raising surface energy and making adhesives perform reliably for up to 24 hours.

Benefits of Pyrosil LSE Surface Treatment

• Enables bonding on HDPE, PP, PE, and other difficult plastics
• Improves adhesion to glass, porcelain, ceramics, and metals
• Extends surface activation window up to 24 hours
• Reduces rework, failures, and downtime

By burning a controlled gas mix of propane, butane, and silicon-organic compounds, Pyrosil forms a stable surface coating that adhesives can grip onto. This makes it ideal for industries like automotive, electronics, packaging, and composites.

Applications Across Industries

From bonding polypropylene parts to preparing glass surfaces, Pyrosil ensures consistent, durable results. Manufacturers worldwide rely on this technology to solve adhesion challenges and streamline production.
