Precautions
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 mixed, 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 in winter, 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.
[Q & A]
There are many reasons cause to unfavorable bonding effect. Please note:
1. The plate is not dry enough or the air humidity is too high, and the moisture absorption of the plate causes the water content of the plate to be high;
2. The glue A/B component is not mixed according to the specified ratio;
3. Non-completely mixing of the glue;
4. The combination of the two components of A and B causes the curing reaction to occur early;
5. After the glue is evenly mixed, it is not used within the pot life.
6. When in winter, the temperature is low, the product may crystallize and agglomerate. It can be used after heating and melting the glue without affecting performance.
7. Please wipe and clean the glue with cloth dampened alcohol on the skin and clothes before uncured, and then wash with soapy water; if it accidentally enters the eyes, rinse with plenty of water, then immediately treat it; if inadvertently swallowed, Do not induce vomiting, drink plenty of egg whites or milk, and seek medical attention immediately.
Protective measures
Due to the individual differences of the operators, the glue may cause allergies to certain parts of the skin, but the product meets the national mandatory standard of GB18583-2008, which is an environmentally friendly product and has no other harm to the human body. It is recommended that your company use the following necessary protection when using the compound glue:
1. Use in a well ventilated environment;
2. Equipped with necessary protective clothing, protective gloves and protective masks;
3. Avoid direct contact with the skin, in case accidentally contact the skin, you can use soapy water to clean;
4. Before glue mix, first open the cover of component B, let the free low molecular substances volatilize, and then take the glue and adjust the glue;
5. If there is an allergic reaction, employees should change jobs.
important notes
1. Due to the ever-changing material of the material to be bonded, material changes may affect the bonding effect. For this reason, be sure to try it before using it in large quantities.
2. Our company solemnly promises that the company's products are produced strictly in accordance with the company's standards. Our company is only responsible for the products themselves and is not responsible for the customer's use of the process.
3. Our company strictly implements the ISO9001 quality system and the ISO14001 international environmental certification system to provide customers with quality and qualified products. The technical opinions provided by our company, whether verbally, in writing or on the experiment, are sincere, but not guaranteed. Users should read the instructions and use the experiment to verify the suitability of the proposed process and use.
4. The company is unable to control the storage and transportation, the environment at the time of use, and the operation process during use. Therefore, the quality problems caused by improper construction of the customer and the associated losses are the responsibility of the user, and it is not the responsibility of the company.
5. No employee of the company has the right to change or waive the above terms!
