Use Characteristics Konson® R-80 is a component of the bonding system resorcinol/ formaldehyde/ silica. In conjunction with a formaldehyde donor (e.g. Konson®HEXA-80 or Konson®HMMM-65) the resorcinol- formaldehyde- resin, responsible for the bonding of rubber to textile and steel cords, is formed during the curing process. This system is suitable for bonding all types of rubber to reinforcing materials, e.g. fabrics, glass fabrics and metals (e.g. steel-cords).

Processing Advantages The predispersion of Resorcinol in a SBR binder allows quick absorption and excellent
dispersion in the rubber. In this way, optimal activity of Resorcinol is assured.
