1. Mixing Method: 100 parts of component A with 90 parts of component B are mixed to be used.

 

2. Coating: 8818 special adhesive applied to the composite device with multi-roll coating systems.

 

3. Viscosity Increase:

 

8818 binder are mixed at an initial viscosity of about 40 ℃ conditions 1000mPa.s, Brookfield RVTDV-Ⅱ, rotor 27.

After about 30 minutes, 5500mPa.s,

About 50 minutes later, 16700mPa.s.

 

 

4. Cleaning: When stopping for more than 30 minutes, coating roller need to use solvent / plasticizer mixture cleaning (refer to safety precautions). Double roller coating unit also needs to be cleaned; the cleaning process must also be the same after the boot.

 

5. Curing: composite article usually requires at 40 ℃ -50 ℃, and completely cured after being stored for 1-3 days.

.
