Resorcinol of high-quality
Resorcinol-80
Application/efficiency: Resorcinol, a necessary component in direct bonding systembetween rubber to metal or dipped fiber. Resorcinol formaldehyde resin, a cure-reactionproduct during resorcinol and formaldehyde, is wide-spread used as keymaterial for enhance adhesion between reinforcing material and rubber compounds.Resorcinol, is pure crystal form normally, hygroscopic by its nature. Byabsorbing moisture, it tends to cake and discolor to brown, and its freezing pointis lowered. It is very hard to disperse uniformly in elastomer. It can obtainexcellent dispersion in compound while add it exceed 150`C during initial mixingtime, but the instability of the adhesion and blooming occur frequently. Thefume vapor is harmful to the health of workers. Loss during the processing can beavoided and no vapor occurs by add crystalline resorcinol in the final mixingtime, but it is difficult to dispersing in mixtures. An unequal adhesive strengthwill happen. Compound designers are persecuted by all above problems for a longterm.
PRT-HDR is made from imported, high purity resorcinol which subjected tospecial treatment and blended with polymer binder and dispersion agent, thus candispersed in compound easily during low temperature mixing, and all the compositionin the PRT-HDR enhance adhesion of compounds. Using PRT-HDR is able to avoidfume vapor of crystal resorcinol in the process of compound, asymmetrical dispersionand hygroscopic by absorbing moisture. Auto weighting technique can be adopted,excellent dispersion, free from agglomerates, moistureproof. All these advantagesensure the homogeneity and stability of the adhesive strength betweenthe rubber compounds and reinforcing material.
Rubber-to-metal bonding is favourably influenced by the excellent dispersionof the granulated chemical. PRT-HDR high dispersing resorcinol is suitablefor use in manufacture of tires, conveyor belts, V-belts, round belts, fire hoses,other reinforced hoses, flexible containers and fabric proofings. When usingPRT-HDR, no powder puffing and environment pollution and no harmful to health
