Hot melt pressure-sensitive adhesive (HMPSA) is a type of adhesive that is solid at room temperature but melts and becomes tacky when heated. It is widely used in various industries and applications where a strong and instant bond is required, along with the ability to stick to different surfaces upon application of pressure.

This formula guide will provide you a true method of making a pressure sensitive hot melt adhesive. The method includes extracting a melt composition comprising a polymer, wherein the polymer has acidic groups covalently bonded, and a metal salt hydrate, wherein the metal salt hydrate has a melting point greater than is lower than the higher processing temperature.
Pressure-sensitive adhesives (PSAs) have a minimum of properties including:

Hot melt pressure-sensitive adhesive properties

aggressive and persistent tack,

adherence to adhesive not exceeding finger pressure,

adhesive retention. sufficient capacity of, and optionally  sufficient coherent power to be removed cleanly from the follower.

Hot melt pressure sensitive adhesives (HMPSAs hereafter) are widely used in industry. In particular, acrylic HMPSAs are often used in applications where color and/or aging properties are important. Typically, acrylic HMPSAs are crosslinked to provide the desired shear properties, and a variety of techniques have been used.
