As for the viscosity of hot melt adhesive, there will always be many customers who will ask whether your hot melt adhesive is strong sticky. This strong sticky means "sticky". However, without specifying the material to be glued, it cannot directly indicate whether the hot melt adhesive is strong or not. Hot melt adhesives are only suitable and not suitable, and there is no strong or weak adhesion. This is the misunderstanding of many customers in the consultation.



Viscosity is the internal friction of fluid, the resistance of relative motion between one layer of fluid and another layer of fluid, that is, the resistance of fluid flow. At the same time, it is also an important parameter of hot melt adhesive. Viscosity is also called viscosity, which refers to the viscosity of hot melt adhesive in the melting state. The lower the viscosity is, the better the fluidity of the hot melt adhesive will be, the easier the adhesive will be produced, and the less the wire drawing will be. Therefore, the viscosity is related to the coating, wetting, permeability and wire drawing of the adhesive. When it is clear which specific material to stick to, it is necessary to select the appropriate viscosity according to the material and shape to produce a good bonding effect. As a professional hot-melt adhesive manufacturer, Weiwang hot-melt adhesive only recommends the most suitable hot-melt adhesive.
