The product will obtain to higher bonding strength when higher curing temperature and longer cured time . the figure curve is the recommended curing temperature and heating rate,Underthe corresponding temperature ,components need the time when they achieve good bonding strength.
Users can set the curing furnace’s temperature parameters according to the solidified characteristic curve of the glue and the heat efficiency of the Reflow Ovens
Performance After Cured
(Cured for 30min@150°C)

Direction For Use
The product should be recovered to room temperature before use, don't open the aluminum foil package before recovered to room temperature(the recovering time of 300ml packaging at least 2-4 hours).
The product should be used at 25°C ,
The glue viscosity will decline under the higher temperature, which influence printing effect; High humidity can increase the glue of moisture absorption which shorten the opening hours of the glue and influence the glue bonding strength. This product opening time is 48 hours at 25 °C,55% Rh.
Suggest to print at the speed of 20-150 mm/s; Drawknife pressure is 3-4 N/cm (Afer scraping, sheet should be clean, and avoid producing wire drawing); the deviating speed from the sheet is 0.1-3.0 mm/s.
Not cured adhesive which is stick on line wires can be erased with acetone or propylene alcohol ethers.
Please seal and chill when not using up the glue.
Application Process
Notice
Keep away from children.
The workshop should be adequate ventilation.
Wash with soapy water if on skin.
Wash with a lot of soapy water and then go for doctor if in eyes.
For more information, please refer to MSDS.
