How much do you know about the “viscosity” and “stickiness” of hot melt adhesive?

Regarding the viscosity and stickiness of hot melt adhesive, many customers will always ask if your hot melt adhesive is strongly adhesive, which means “sticky”. Without specifying what material to stick, it is not possible to directly determine whether the hot melt adhesive is strong or not. Hot melt adhesive is only suitable or not, and there is no strong or weak viscosity, which is a misconception among many customers in consultation.

Viscosity is the internal friction of a fluid, which is the resistance to relative motion between one layer of fluid and another, i.e. the resistance to liquid flow. It is also an important parameter of hot melt adhesive, viscosity, also known as viscosity, refers to the degree of thinness of hot melt adhesive in its melted state. The lower the viscosity, the better the flowability of hot melt adhesive, the easier it is to produce glue, and the less wire drawing. Therefore, the viscosity is related to the coating, wetting, permeability, and wire drawing phenomenon of the adhesive. When it is clear which specific material to stick to, it is necessary to choose the appropriate viscosity based on the material to be glued and the shape, in order to produce a good bonding effect. As a professional hot melt adhesive manufacturer, Senlai Hot Melt Adhesive only recommends suitable hot melt adhesives. The more expensive the hot melt adhesive, the better. Suitable hot melt adhesives are the best.
