Sheet bonding adhesive

Brand : MAGPOW

Product origin : China

Delivery time : 25-35 DAYS

Supply capacity : 100 TON/MONTH

[Applicable Scope]
Sheet bonding adhesive is mainly used for composite bonding of marble-marble, marble -granite and marble-ceramics.


[Performance Characteristics]

Sheet bonding adhesive is the modified epoxy adhesive, which has advantages of high adhesive strength, low stress, and minimal shrinkage after curing and no air bubble after curing, thermal expansion coefficient close to that of Stone, faster curing speed, moderate viscosity, easy brushing, convenient operation, abrasion resistance, aging resistance and good cold & hot alternation resistance.

[Application Method]

1. Polish and level the composite plate to certain thickness; remove dust, gravel, oil and other impurities on the surface; and dry it to remove moisture.
2. Mix the adhesive evenly according to the specified proportion and scatter it on the bottom plate; use a adhesive mixing knife to apply adhesive on the stone bonding parts and apply pressure to the bonding parts by moving with hands, to exclude air between plates and to make adhesive fill the plates; there must be appropriate amount of adhesive outflow.
3. Align the upper and lower stones, place them steadily for curing and adopt fixture to apply uniform pressure.
4. At room temperature, the pressure on plates can be released after 2-3 hour curing and the plate will be put into next process after 24 hours. At low temperatures in winter, the stacked plates will be heated evenly for 2-3 hours in 50-60 ℃ curing barn and will  be put into next process after being naturally cooled to room temperature.
5. The reference adhesive amount for composite plate is 400-600g/m2; it is recommended to adopt single-sided or double-sided adhesive coating.
6. Add special toner in the adhesive according to the different colors of stones and adjust it into a color similar to the stone; the largest adding volume of toner is 3‰ of adhesive amount.

[Protection Measures]
For different workers, the glue may irritate the skin, but the product meet national standard GB18583-2008, it is environmental friendly and no harm to human body.
When using this glue, please take the protections as below:
Use the glue in the ventilate environment
Wear the protection cloths, gloves and mask
In case the glue contact skin directly, if any, clean with the soap water
Before mix the glue, open the cap of Part B first, wait for the volatility of the free low molecular materials
If any irritation to the skin, better to change to other jobs.

[Cautions]
1. The stone composite surface must be leveled, to increase the composite bonding strength and to reduce the adhesive consumption; the stone composite pressure should be evenly distributed.
2. Adhesive mixing ratio must be accurate and adhesive mixing should be even, so as not to affect adhesive bonding strength. 
3. In order to ensure the composite quality, after coating adhesive and applying pressure, there must be certain amount of adhesive outflow. 
4. The plate should not be removed before the adhesive is fully cured. 
5. The application temperature should not be less than 5℃; the adhesive should be heated appropriately in winter, to increase the temperature of stone surface.
6. As the adhesive should be used immediately after mixing, the mixed adhesive must be used within applicable time. The high construction temperature is, the more adhesive amount and shorter application time will be. If the mixed adhesive is excess, the adhesive should be used separately. 
7. The apparatuses used to take two groups of adhesive must not be mixed; the remaining mixed adhesive must not be placed into the original package. 
8. If the application is inconvenient due to the high viscosity of adhesive liquid, the adhesive will be heated in 40-60 ℃ water to reduce its viscosity.
9. As the product will cause allergies for certain skins, please make certain protection upon application.
10. Do not mix the lid of adhesive, fasten the lid after application and do not mistakenly eat the adhesive!
11. Because of the different physical, chemical nature of stone, please use the product for trail before formal use and mass production, in order to avoid errors!
