Resin: 24kg/drum Resin: 200L/drum Resin: 1000-1250kg/drum
Application
1.Preparation:
Prepare a clean and dry drum for mixing the adhesive.
Mixing tool: Sticks for manual mixing or electric mixer.
Electronic scale: It would be better if the electronic scale can accurately weight to one decimal.
2.Substrates Surface Treatment:
The substrates should be clean and dry and of no grease, dust, or other contaminations. The substrates can be cleaned by alcohol or acetone. If the metal surface is coated with primer, or the surface is polished, the adhesion can be improved significantly.
3.Well Mixing
The resin should be uniformly stirred before it is mixed with the hardener (8200). Mix the two components uniformly. Mix for 1-2 more minutes after the two components color is well mixed. Use up the mixer as soon as possible before its pot life, or less frequent principle can be taken.
4.Adhesive Coating:
The adhesive can be coated with spreading machine, rollers or serrated scrapers manually. The adhesive should be coated uniformly on the substrate surface. The recommended dosage is 200-400G/M2. The dosage varies with the roughness of the substrate surface.
The adhesive should be coated within its pot life.
5.Pressing:
Substrates have been coated with adhesive should be pressed within open time, or the adhesion strength will be affected. Raise the compounding pressure as high as possible without affecting the material forming.
6.Pressing time
The curing speed and the time to form adhesion vary with the temperature. The curing speed is slower and it takes longer time for pressing as the temperature is lower; The curing speed is faster and it takes shorter time for pressing as the temperature is higher. The pressing time is 4 hours under 23.
7. Working Condition
Recommended working condition: Temperature 5-30, relative humidity <80. The curing speed will be affected if the temperature is too low. And too much bubble will be formed if the humidity it too high.
When stored at the recommended conditions in original, unopened containers, this product has a shelf life of 9-12 months. The shelf life of polyurethane sealant is related to the temperature and humidity of the environment. The recommended storage temperature is 5-25° C, humidity is <50% RH. It is strictly prohibited that the transportation or storage temperature is over 30° C or the humidity is over 80% RH. And high-temperature container transportation is prohibited as well. In the long-time high temperature and high humidity storage environment, the product is easy to get viscous, extrusion will be deteriorated and shelf life will be shortened.
