The surface of films made from rubber, especially natural rubber, have tendency to stick together due to its naturally high surface tack.
Anti-tack agents are materials designed to eliminate the self - adhesive quality of rubber products and are applied to products to form a thin protective anti-tacky layer on the surface.
Anti-tack agents are commonly employed in the rubber and plastics industry in order to prevent adhesion of rubber or plastic objects to themselves, to each other and/ or to other objects.
To prevent such adhesion of rubber or plastic articles to, themselves or to each other, it is common to employ so-called anti-tack compositions which are usually powdery materials such as talcum, zinc stearat, or aluminum stearatwhich are applied to the rubber or plastic material or articles.
While such powdery anti-tack agents and compositions appear efective in preventing adhesion of the above mentioned materials to themselves or to each other, such powdery materials have serious shortcomings.
