Hot melt pressure sensitive adhesives are a unique class of adhesives because they do not cure or react chemically when applied.

It is a kind of viscoelastic material that exhibits both viscous (flow) and elastic (resistance) properties.

Hot melt pressure-sensitive adhesive is usually placed on the substrate in the form of tape and applied with pressure. The adhesive will immediately have a certain initial viscosity, but will continue to flow on the surface.

Over time, the contact area will gradually increase and reach a higher level of strength.
