Application
Its adhesion performance will be affected by substrates, release paper and application environment, so trial run is necessary to determine whether the adhesive is suitable.
There should be no dust or oil on the surface of substrates and release paper, also the substrates and release paper should be treated to constant temperature and humidity before application.
Application methods: roller or spray
Operating Temperature Guidelines
The operating temperature of 160-180℃ is recommended. The glue viscosity can be adjusted by the temperature: summer appropriate down 5-10 ℃, raised 5-10 ℃ in winter.
Temperature Limits
Application-temperature of the labels: between ＋15°C and 50°C
Temperature resistance of the applied label: from －20°C to ＋60°C
Warnings
-
Don’t mix the product with other adhesives.
-
Keep the adhesive containers covered to avoid dust or contamination.
-
Stop heating if you don’t use it for a long time to avoid the carbonization of the adhesive.
