Resorcinol of high-quality Resorcinol-80 Application/efficiency: Resorcinol, a necessary component in direct bonding system between rubber to metal or dipped fiber. Resorcinol formaldehyde resin, a cure-reaction product during resorcinol and formaldehyde, is wide-spread used as key material for enhance adhesion between reinforcing material and rubber compounds. Resorcinol, is pure crystal form normally, hygroscopic by its nature. By absorbing moisture, it tends to cake and discolor to brown, and its freezing point is lowered. It is very hard to disperse uniformly in elastomer. It can obtain excellent dispersion in compound while add it exceed 150`C during initial mixing time, but the instability of the adhesion and blooming occur frequently. The fume vapor is harmful to the health of workers. Loss during the processing can be avoided and no vapor occurs by add crystalline resorcinol in the final mixing time, but it is difficult to dispersing in mixtures. An unequal adhesive strength will happen. Compound designers are persecuted by all above problems for a long term. PRT-HDR is made from imported, high purity resorcinol which subjected to special treatment and blended with polymer binder and dispersion agent, thus can dispersed in compound easily during low temperature mixing, and all the composition in the PRT-HDR enhance adhesion of compounds. Using PRT-HDR is able to avoid fume vapor of crystal resorcinol in the process of compound, asymmetrical dispersion and hygroscopic by absorbing moisture. Auto weighting technique can be adopted, excellent dispersion, free from agglomerates, moistureproof. All these advantages ensure the homogeneity and stability of the adhesive strength between the rubber compounds and reinforcing material. Rubber-to-metal bonding is favourably influenced by the excellent dispersion of the granulated chemical. PRT-HDR high dispersing resorcinol is suitable for use in manufacture of tires, conveyor belts, V-belts, round belts, fire hoses, other reinforced hoses, flexible containers and fabric proofings. When using PRT-HDR, no powder puffing and environment pollution and no harmful to health
