About the ASI SI Series Surface Insensitive Cyanoacrylate

ASI SI Series Cyanoacrylate is a super glue used in applications that require fast cure speeds. The SI Series super glue is perfect for bonding difficult substrates, acidic surfaces, wood, PVC and substrates that contain plasticizers like certain types of EPDM, etc. 

The SI Series super glue from ASI is the go-to super glue for most applications where a strong, permanent bond and fast set times are required. 

Benefits of the ASI SI Series Cyanoacrylates

• Bonds almost any substrate
• Faster than most super glues
• Single component (no mixing or nozzles required)
• Cures at room temperature
• Good for bonding most substrates
• Fast cure time
• Dispensing can be automated
• Long term bonds
• Economical
• Meets most military (MilSpec) standards
• Can replace heavy mechanical fasteners
