GENERAL DESCRIPTION
TECBOND 7718/12/250/black is a polyamide hotmelt adhesive with a very low viscosity for potting and encapsulating that runs
well through most 12mm glue guns.
The formulation is pigmented ‘Black’ to prevent the encapsulated components being visible.
The setting time is usually less than 2 minutes, but does depend on the amount and temperature of the adhesive applied. For
small applications a setting time of 5-10 seconds is common.
The use of a hotmelt speeds up application as there is no mixing and any unused material remains in the glue gun ready for
next time, so there is no waste.
Application by glue gun is quick, accurate and safe.

Please note, the test data recorded is the normal/typical value
This product has been tested and complies with UL V0 fire retardency requirements.
Important Note.
This is a polyamide-based material and consequently will absorb a small amount of moisture from the atmosphere. This does not
affect the performance and all test data relates to fully saturated material. However, even a small amount of moisture contamination
will turn into a large amount of steam at glue gun temperature. This will cause the glue gun to drip, foam and glue stick to back up.
Please keep the adhesive sealed in the special packs provided. Moisture contaminated adhesive may be dried in an oven at 70ºC
for 24-48 hours.
