The way WBP plywood is tested is by boiling the sample in boiling water.
If the sample is boiled in boiling water for a long time without opening the glue, then it can be proved that the plywood has good WBP properties.
The common WBP glue is melamine glue and phenolic glue.
In general, ordinary melamine glue can keep in boiling water for 4-8 hours without opening, good melamine glue can keep for 10-20 hours without opening;
While normal phenolic plywood will remain in boiling water for about 24-72 hours without breaking, the best phenolic glue will retain its WBP properties forever.
