DESCRIPTION：Adhesive resin N-8 is a thermoplastic resorcinol - formaldehyde (RF) novolac resin.
PROPERTIES：1) Adhesive resin N-8 resin plays the role of resorcinol, RF or RFS system in rubber compounding applications. This resin can enhance the adhesion between rubber compounds and steel wire or synthetic fibers.2) During the vulcanization of rubber compounds, resorcinol based Adhesive resin N-8 resin can react with the methylene or formaldehyde donor materials, such as hexamethoxymethylmelamine(HMMM) and hexamethylenetetramine (HMT), to form crosslinked network structures. There are two types of reaction expected with Adhesive resin N-8 resin during the rubber curing process. The first cross-linking reaction, which can produce a chemical bond between the reinforcing cords and resin, enhances the adhesion between rubber and cords. Another cross-linking reaction, which may occur during rubber vulcanization between the resin and double bonds of rubber molecules, enhances the cured rubber compounds physical and mechanical properties. Adhesive resin N-8 resin retains good adhesion properties of brass plated steel cords to rubber compounds under the heat, humidity and salt aged conditions. Therefore, Adhesive resin N-8 is an ideal adhesion promoter to enhance the adhesion between rubber and the synthetic fiber cords and brass or bronze coated steel cords, particularly in truck, bus and passenger tire applications.
