           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.             Package NO:6416054 200g NO:6416034 400g   Storage 6 months sealed at 2-8°C.
