| DIRECTIONS FOR USE |
Manual mixing process (230g mixing volume)
1. Preheating: AB components in at low temperature, the viscosity will become high, it is recommended to preheat to 20 ~ 25 ºC, easy to use.
2. Mixing: Weigh the components A and B according to the proportion, mixing vertical stirring rod, clockwise (or counterclockwise) in the same direction and rapid mixing for 3 minutes, 110-120 circles/min, pay attention to the bottom of the container, the edge of the
The department should be stirred evenly, otherwise, there will be a localized phenomenon of non-curing.
3. Potting: Pour the mixed products into the device (Note: 2-3 minutes to fill the product with glue), if the product has a complex structure and large volume, it should be potted in stages.
After using
After using
The operating container will be cleaned before use. Mixing the main agent and stiffening agent, With the different kinds of stiffening agents and quantity. The process should be completed as soon as possible.
