Product Description: CRJ-418 is a thermoplastic resin made from octylphenol and formaldehyde. It is typically used to increase tack in natural rubber and synthetic elastomers, including SBR, BR, IIR and IR. It is ideally suited for the splice and under-treated cements in tire construction. Applications: CRJ-418 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 CRJ-418 is typically used at 3-8 phr level. Alternately, CRJ-418 may be used as a component of an under tread or splice cement. In this application it is typically used at 5-20 phr level. Information provided by Akrochem Corporation |
