- Very high heat resistance (> 150°C) and cold flexibility
- Excellent water resistance
- Resistant to most solvents
Processing
Recommended working temperature
in the melting container 100 to 140°C
at the application roller 100 to 140°C
Recommended application amount
(depending on substrate) 50 to 400 g/m²
Since the product will cure when it is exposed to moisture, storage and application must be done under dry conditions. For this reason, the product is delivered in airtight containers.
Cleaning
Cleaning the system periodically or prior to changing to an alternative reactive hot melt will reduce internal build-up of adhesive residue. Application devices such as wheels and rolls that expose reactive adhesive to the air should be thoroughly flushed with TECHNOMELT PUR CLEANER 3 at the end of a production run or at any time when there is buildup and gelling. For cleaning the melting unit with TECHNOMELT PUR CLEANER 4 is recommended.
