Specification:

Application:

• As an esterification catalyst for rosin esters, it can shorten the
  reaction times and produces a resin with reduced color and
  low acid number.

• It also imparts a “carry through” antioxidant effect by offering
  improved heat stability of the final resin.

• Using it together with our bleaching agentsand antioxidants
  the balance properties of the finished rosin products will be very perfect;
