It is oil soluble, compatible with various synthetic rubbers, and is ideally suited for use in splice and under-tread cements for tire construction. CRJ-418 Tackifier Resin is supplied in flake form. There is little dust and for this reason it is readily dissolved in solvent, easily blended into rubber stock, and will not contaminate work areas or equipment. CRJ-418 Resin can be used either as a stock additive to impart tack, or as a component of an undertread or splice cement. In the former application it is used at 3-8 phr level, and in the latter, at 5-20 phr level. CRJ-418 Tackifier Resin is 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. Thermoplastic alkylphenolic tackifier. Offers tenacious bonds with various synthetic rubbers. Use level: 3-8 phr.
