How to use

Use process

For Dual tube, when in use, assemble a static mixing tube for mixing operation, pay attention to the 10cm front end of the glue to ensure uniform mixing;
For barreled products, a platen pump must be used to supply glue, and then mix and construct after passing through the metering device;
If you need a dispenser, please consult BEGINOR;
