Water can be increased or reduced depending on using conditions.
Measure and prepare glue powder, add 2/3 of total water and then
mix them until all glue powder dissolves in the water.
Add the remaining water and mix for using. (Use before gelation,
and below 25℃, the pot life is 2-3 hours usually)
Moisture control of plywood or wood
Cold pressing: minimum 6%, optimal 8-12%, maximum 15%
Hot pressing: minimum 5%, optimal 7-9%, maximum 12%
In storage, curing happens when the wood glue powder
contacts with moisture and the glue becomes useless. Therefore, the
