What are the characteristics of environmentally friendly edge sealing hot melt adhesives?
1. The solid content is 100%, and it has void filling properties, which avoids the defects such as deformation, dislocation and shrinkage of the adhered parts caused by edge curling, air bubbles and cracking. Because there is no solvent, the moisture content of wood does not change, and there is no danger of fire and poisoning;
2. Fast bonding, the interval between gluing and bonding is only a few seconds, the saw head and trimming can be completed within 24 seconds, no drying time is required, and it can be used in a continuous and automated wood bonding line, which greatly improves the production. efficiency, saving plant costs;
3. Wide range of uses, suitable for bonding various materials;
4. It can be bonded several times, that is, hot melt adhesive is applied to the wood. When the requirement is not met due to cooling and solidification, it can be reheated for secondary bonding.
