Adhesive bonds PP, PE –and other LSE materials – permanently

IPS Adhesives has introduced an adhesive that provides strong, reliable bonding on low surface energy (LSE) materials such as polypropylene (PP) and polyethylene (PE). The new SCIGRIP SG400LSE adhesive requires no surface preparation and has low sag, as well as short working and fixture times.

“Product design engineers seeking the many advantages of low surface energy plastics like PP and PE have long been plagued by difficulty in bonding them with adhesives. We are excited that our chemists have solved that problem for engineers. Our new SG400LSE adhesive bonds PP, PE, and other LSE materials without surface preparation giving the engineering community new flexibility in creating stronger, lighter, and more durable products,” said Scott McDowell, IPSA President.

The new SG400LSE product is a two-part translucent, methyl methacrylate adhesive (10:1). It cross-bonds plastics to metals such as steel and aluminium. Unlike adhesives that claim to bond LSE materials and fail after a few months, SG400LSE sets in less than 24 hours, is practically indestructible once it does set, and bonds well to metal.

Areas in which the SG400LSE solution is already proving valuable include bonding large plastic storage tanks, such as those used for petroleum, grey, or black water; automotive interior fixtures; medical devices; workstations; casework; truck panels; outdoor furniture; and signage.
