Antioxidant 623

Antioxidant 623

Application:
1. It has double effect of both free radical termination and hydroperoxide decomposition.It means that it has the double functions of both the primary antioxodant and the secondary antioxidant.
2. It is a kind of disulfide compunds.so it can act as vulcanization agent,anti-crystallization agent,antioxidant,catalysts in the manufacturing of light-colored rosin, disproportionated rosin, rosin resin, rosin esters,resins,adhesives,petroleum oil and waxes and deep processing.
3. It is viscous liquid at room temperature. it is recommended to preheat the packing drum to 70℃ to 80℃ to facilitate operations.maxium handling and blending temperature:100℃
4.Dosage for reference:0.1% to 0.3%. Precious metals (such as platinum, palladium) used as disproportionation catalysts could be expensive. It is an ideal replacement for them with good quality and low costs.

Application:

1. It has double effect of both free radical termination and hydroperoxide decomposition. It means that it has the double functions of both the primary antioxodant and the secondary antioxidant.

2. It is a kind of disulfide compunds.so it can act as vulcanization agent,anti-crystallization agent,antioxidant,catalysts in the manufacturing of light-colored rosin, disproportionated rosin, rosin resin, rosin esters,resins,adhesives,petroleum oil and waxes and deep processing.

3. It is viscous liquid at room temperature. it is recommended to preheat the packing drum to 70℃ to 80℃ to facilitate operations.maxium handling and blending temperature:100℃

4.Dosage for reference:0.1% to 0.3%. Precious metals (such as platinum, palladium) used as disproportionation catalysts could be expensive. It is an ideal replacement for them with good quality and low costs.


Features:

1.The effects of antioxidation and color-fade of rosin and rosin resins (such as Glycerol ester of rosin, rosin pentaerythritol ester and malic acid resins) can be improved by adding antioxidant 623 with the amount of 0.2% to 0.3%, causing the color to improve with the subtractive effect achieving 2 to 3 units in the Gardner color scale.

2.Disproportionation of rosin: antioxidant 623 is an efficient catalyst for the disproportionation of rosin. It converts instable conjugated double bond in the rosin molecule into stable conjugated double bond with an aromatic ring structure, which means to convert the abietic acid into dehydroabietic acid. 

3.Anti-crystallization of rosin: Rosin is a non-crystalline transparent solid, but it tends to crystallize. Crystallization of rosin causes a reduction in rosin’s transparency and solubility, affecting its usage. Adding 0.2% antioxidant 623 to the rosin can improve its anti- crystallization performance.
