Product Description: HRJ-10420 is a thermoplastic resin made from octyphenol and formaldehyde. The resin is typically used to increase tack in natural rubber and synthetic elastomers, including SBR, BR, IIR and IR. Applications: HRJ-10420 resin can be used as a stock additive to impart tack and used wherever tenacious bonds are necessary, especially with synthetic rubbers, which do not possess the inherent tack necessary for plied-up construction. In tire building, for example, plies, tread stock, and sidewalls must hold fast to the green tire until it is vulcanized or cured into an integral unit. For this application HRJ-10420 is typically used at 3-8 phr level. Information provided by Akrochem Corporation |
