Description
LORD® Accelerator 19 is a mix-in curative used with LORD 200, 400, and 500 series acrylic adhesives to create structural adhesive systems capable of bonding a wide range of prepared or unprepared metals and plastics.
This composite product includes multiple variations of Accelerator 19, including standard off-white paste, black paste, and versions containing glass beads. When combined with the appropriate LORD acrylic adhesive, the system cures at room temperature and provides resistance to common environmental conditions.
Accelerator 19GB includes glass beads that control adhesive bondline thickness, helping maintain a consistent bond gap during assembly.
