Does the viscosity of environmentally friendly edge sealing hot melt adhesive reflect the performance of the adhesive?

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.Low-viscosity hot melt adhesives have a smaller coating amount and better wetting properties.Some hot melt adhesives with low viscosity and fast cure speed may also have high tack strength.Therefore, the viscosity of the environmentally friendly edge sealing hot melt adhesive cannot directly reflect the performance of the adhesive.

For poor-quality particleboards, low-viscosity hot-melt adhesives should not be used for edge sealing, but higher-viscosity hot-melt adhesives should be used.The high viscosity hot melt adhesive has poor fluidity, and it is not as easy to enter the pores of the edge of the particleboard as the low viscosity hot melt adhesive when applying glue.So that the hot melt adhesive can be fully coated on the edge of the board.
