The difference between PUR hot-melt structural adhesive and ordinary hot-melt adhesive sticks/blocks:
Common point: they all need to be heated to turn solids into liquids, and then stick to
catch. But the principle of curing bonding is different:
1.PUR hot-melt structural adhesive: turn solids into liquids for bonding and bonding
After bonding, it is cured by moisture in the air.
After bonding and molding, if it is heated and separated, it will be difficult to separate. Even
Resistant to high and low temperatures
2. Ordinary hot melt glue stick/block: heat the solid into liquid for bonding,
Mainly heat the solid to turn it into a liquid for forming and bonding. After bonding, add
hot, it can be split. That is to say: can not withstand high temperature and low temperature
