APPLICATIONS

Both saturated and unsaturated rubbers can be vulcanized using various peroxides. But a good state of cure (higher cross linking density) is achieved when a co-agent is used along with peroxide. Thus, a co-agent like Aurosin-6860 gives higher tensile strength, higher tensile modulus, higher cold and hot tear strength, lower compression set, lower abrasion loss, a very good heat resistance, and better elongation at break, at the same time increasing hardness, compared with a peroxide alone vulcanizate.

Aurosin -6860 is an excellent nitroso-amine free scorch retarder, giving very good scorch safety for extruded, injection moulded rubber compounds, at the same time with out affecting cure rate.

Aurosin–6860 is a very good rubber-to-metal adhesion promoter for metals, plastics and fibres. It produces extremely strong rubber-to- metal adhesion without use of external adhesives. Strong rubber-to-metal bonds are achieved with rubbers like NBR, HNBR, CR, SBR, EPDM, PBR, Silicon, Hypalon and other rubbers. A good adhesion is achieved with a number of untreated metals like steel, brass, copper zinc, aluminum and galvanized steels. Good adhesion is also obtained with plastics/ fibres like PET, nylon, PP/PE, PTFE, Aramid / Kevlar, glass fibres etc.

Aurosin-6860 peroxide co-agent is extensively used in rubber based products like belts, hoses, cables, rubber rollers, foamed rubbers, building profiles and varieties of moulded products where excellent heat resistance, lower compression set and good hot tear strength etc are required. It is also used in peroxide based type flaps (EPDM), cables, foamed products and adhesives.

 
DOSAGE

• UHR conveyor belts/ V- belt compounds: 2-5 phr
• Hose compounds: 2-4 phr
• Rubber Bushes / roller compounds: 5-8 phr
• Extruded profiles: 2-6 phr
• EPDM Tyre falps= 2- 4.5 phr
• Cable compounds: 2-8 phr

STORAGE

Co-agent Aurosin-6860 is a metallic anhydrous salt, which may readily absorb moisture on exposure at humid atmosphere.So, it is recommended to store the material between 50-90ºF.Direct exposure to heat , sunlight, oxidizing additives,and strong oxidizing/reducing agents to be avoided.
