Application

Bleaching agent OF-9 is alkylphenol disulfide polymer, performs as a multifunctional agent for gum rosin and the derivatives as following:

(1)Excellent bleaching agent in the disproportionation of rosin or rosin esters. It reduces greatly the color of gum rosin and gum rosin ester.

(2)Excellent antioxidant in the disproportionation of rosin or rosin esters, improving the heat resistant and light resistant ability.

(3)Excellent catalysts in the disproportionation of rosin or rosin esters, speeding up the reaction.

(4)Excellent stabilizer in the disproportionation of rosin or rosin esters, prolonging the stability of gum rosin and rosin ester under light and heat exposure.

Advantages
