by Release agent is an interface coating used on two surfaces that are easily adhered to each other, which can make the surface of the object easy to detach, smooth, and clean.
Release agents are used in various molding operations such as glass fiber reinforced plastics, metal die-casting, polyurethane foam and elastomer, injection molding thermoplastics, vacuum foam sheets and extruded profiles.
In molding, sometimes other plastic additives such as plasticizers may seep out onto the interface, and a surface remover is needed to remove it.
