Edge adhesive viscosity and can not directly reflect the performance of plastic
good or bad. Under normal circumstances, the higher the viscosity of the edge
sealing adhesive, the better the initial adhesive strength,but the worse the
coatin but the worse the coating performance. Low-viscosity hot-melt
glue smaller amount of wetting better. Some high viscosity hot melt adhesive
curing, it's also possible to have a high initial strength.
For poor quality particleboard, edge sealing need to use high viscosity hot
melt adhesive, which is because the high viscosity of the hot melt adhesive
is poor, when the glue is not as low viscosity hot melt adhesive into the
edge of the chipboard easy to enter the pores , So that the hot melt adhesive
can be fully coated in the edge of the plate.
