Steps for usage
1. The water used for grinding and thickening of the plates should be clean and non-polluting fresh water;
2. The board to be laminated should be free of impurities such as dust, dirt, sand and oil;
3. The board to be laminated must be dry by oven or under natural condition
4. The surface of the composite material must be in flat.
5. Firstly mix the glues of components A and B separately with an electric mixer.
6. Mix the glue according to the specified ratio A:B=2:1 (by weight), and then stir evenly with an electric mixer.
7. Please use the specialized toner. The maximum amount of toner is 0.5% of the amount of glue.
8. Scraped back and forth with a scraper, and the glue is evenly applied on the bottom plate. According to the looseness of the material, single or double-sided glue can be applied;
9. Composite the plate, reciprocally shift the plate by hand and apply pressure to remove the air between the plates, so that the glue is fully filled, and there must be proper outflow of glue;
10. Align and press the plate up and down, the pressure should be evenly distributed, and the pressure method can be determined according to the actual situation (jack or clamp pressurization, etc.).
11. After standing under pressure, it can be solidified. It can be loosened after being cured at room temperature (25 °C) for 2-3 hours. After 24 hours, it can be put into the next process;
12. Waiting for solidify under pressure. Remove the pressure after being cured at room temperature (25 °C) for 2-3 hours. After 24 hours, it can proceed to the next process.
13. Please use the special cleaning agent to clean the tools before the glue is uncured.
 Scrape off the residual glue when it is not cured

[Notes]
1. Please note that the tools of components A and B cannot be mixed;
2. Be careful not to leave a dead angle when stirring;
3. Do not put the mixed glue back into the original packaging;
4. After the glue is mixed, it must be used up within the usable time. If the glue exceeds the usable time will be heated and forbidden to use. For example,mixed glue in 3kg must be used within 10 minutest at 25~30°C, ; more the glue mixe,, the higher the temperature, the shorter the pot life; when mixed in large amount glue, please divide the glue and put on slabs.
5. Do not mix the lids of components A and B. Please cover the lid at any time during use to avoid absorbing moisture from the air and falling into dust;
6. If the special toner is not added, it will affect the curing speed and bonding strength of the glue;
7. If the temperature is low, the viscosity of the glue is large, and it is inconvenient to use. Please heat up in a water bath at 40-60 °C to make the viscosity smaller, then it will be easy to mix glue.
8. The ideal temperature for operation is 25-35 °C, and the air humidity is less than 75%.
9. The thickness of the glue should be appropriate. Under normal circumstances, the thinner the glue layer, the smaller the defect, the smaller the deformation, the smaller the shrinkage, the smaller the internal stress and the higher the bonding strength. Therefore, under the premise of ensuring no glue shortage, please control the glue layer thickness to be 0.2-0.3 mm, and the reference consumption is 400-600 g/m2.
10. the construction temperature can not be lower than 5 °C, when temperature is lower than 15 °C, the curing speed of the glue will be significantly slower, please heat up to accelerate the curing speed; when the temperature is low, the composite sheet can be placed in baking room at 50-60 °C for 2-3 hours, and naturally cooling to room temperature to enter the next process;
11. Recommended process: After the adhesive layer is initially cured at 25-35 ° C for 2-4 hours, the laminated sheet is placed in a baking room, and then raise temperature to 60 °C for 1 hour, and then increase to 80 °C for 1 hour, then cool under the room temperature, and remove the the pressure.
12. Do not move the sheet before the glue is initially cured.
