The moisture content of the edge banding wood is unqualified (>18%), and the natural drying during the use of the door leaf produces internal stress, resulting in cracking and deformation of the edge banding.
In general, the higher the viscosity of the edge sealing hot melt adhesive, the better its initial tack strength, but the worse the coating performance.
EVA (ethylene-vinyl acetate copolymer resin) base material hot melt adhesive can be divided into two types with filler and without filler, the limitation is poor heat resistance；
Uses:Edge banding adhesive for all kinds of boards.
Advantages: easy to package,transport, and store, solvent-free,pollution-free, and non-toxic;high added value, high bonding strength, and fast speed.
It is a plastic adhesive. Its physical state changes with temperature within a certain temperature range, while its chemical properties remain unchanged.
