Introduce:
- Two-component adhesive, room-temperature curing, high-viscosity, base on polyurethane adhesive allowing for use in a wide range of applications;
- Resistant to media and corrosive substances;
- Compliance RoHS standard 2015/863/EU;
- Passed the ANSI/UL 94 HB flame retardant test.

| Glue can be packaged in a ready-to-use Automix dual cartridge for use with the DELO Xpress 902 glue gun or in large bottles for industrial production. | |
Application:
- DELO-PUR9694 is multi-purpose, bonding glass/metal, PBT, PET, and many other materials.
- Fix components with passivation surfaces (Ferrite, PBT, Al, PET foil), such as coils, capacitors, and plugs, etc. on the FR4 printed circuit board to prevent vibration;
- The glue has a good resilience to the touch, high strength for both static and dynamic loads, good response to large gaps due to its ability to resist vibration during operation.
- Typically, after cured, adhesives can use in a temperature range of -40 oC ~ +125 oC, depending on the application.
Some typical applications of PUR9694 glue:
1. Fix components on printed circuit boards as protection against vibration

Curing process:
- The glue dries quickly at room temperature (23 0C).
- Heat curing for the glue will help the glue dry faster, but it may cause a change in the physical properties of the glue.
