Rubber tackifiers

Resorcinol is used primarily in the rubber industry for tyres and reinforced rubber products (conveyer belts, driving belts) and in high-quality wood adhesives, which are made from resorcinol, phenol and fonnaldehyde. It is also used in the preparation of dyes and pharmaceuticals, as a cross-linking agent for neoprene and a rubber tackifier, and in cosmetics (Lewis, 1993 Schmiedel Decker, 1993 Krumenacker et al., 1995). 

Use Resorcinol-formaldehyde resins, dyes, pharmaceuticals, cross-linking agent for neoprene, rubber tackifier, adhesives for wood veneers and rubber-to-textile composites, manufacture of styphnic acid, cosmetics.

The earliest PSA tapes began to make their appearance at the turn of the century. Most popular were the cloth tapes used in medical applications, holding bandages and appliances in place. All these were based on natural rubber/tackifier formulations reinforced with zinc oxide [2,3].

The adhesives used on tapes are either thermosetting or thermoplastic. The thermoset adhesives consist of rubber, acrylic, silicones, and epoxies, whereas the thermoplastic adhesives are generally acrylic or rubber. Tackifying resins are generally added to increase the adhesion.

Gum rosin is obtained from tapped pine resin from living pine trees. Pine trees bleed crude resin when they are cut. In a rather labor-intensive operation, this crude resin is collected from the tapped trees and processed. Gum rosin and turpentine are obtained from this crude resin. Sometimes the gum rosins, which are composed of abietic acid, are used directly in rubber compounds as tackiflers. These gum rosins are sometimes chemically modified through either hydrogenation (to improve their aging properties) or esterification for use in rubber. The turpentine is sometimes processed further to separate out the S-pinene for polymerization into polyterpene resins for use as a rubber tackifier.

When the supplier manufactures the A S, it mixes or polymerizes a base polymer with other raw materials solvents, water, resins, rubbers, tackifier, plasticizers, fillers, hardeners, catalysts, additives, etc. In order to ensure that this mixing has occurred properly in the right proportions, and that the finished A S meets its specifications (as indicated on its TDS), the manufacturer usually measures several significant characteristics.
