We use two common and reliable ways to produce Special triphenylphosphine for resin curing agent. The first one is the Grignard method: we react bromobenzene with magnesium to prepare an active reagent, then mix it with phosphorus trichloride at low temperature, and finish with purification. The whole process must be kept away from water and oxygen. The second one is the Friedel-Crafts method: we take benzene as the main raw material, add a Lewis acid catalyst, then go through washing and purification. The raw materials are affordable, and the final product mixes well with all kinds of resin curing systems.

We carry out strict quality control during the whole production of Special triphenylphosphine for resin curing agent. We only choose raw materials with purity ≥99. 5% to avoid unwanted impurities. We carefully control reaction temperature and material ratios, and use recrystallization to remove leftover impurities. Every step is strictly managed to make sure our TPP works steadily with resin curing agents and fully meets the standards for resin curing production.
