There is no black stains appeared during the test. We adopt the unique production process to control non impurities, and even under very high temperature, our dimer acid still maintain the excellent stability. If there are impurities in dimer, the down-stream products such as polyamide resin may appear black stains.
This test is mainly to check the transparency of dimer acid in the low temperature. Thanks to NON phosphate ion and low percentage of monomer, it is easy to find out that the transparency of our dimer acid is very good under low temperature. If there are phosphate ion and high percentage of monomer, the down-stream products such as polyamide resin may become sticky and harden, and the viscosity may be very low.

Q: What is your test instrument for viscosity? A: NDJ-79 made in China. The viscosity tested by NDJ-79 is smaller than tested by BROOKFIELD made in America under the same conditions. Q: How long does the polyamide resins totally dissolve in the solvent? A: Usually, it takes about 30 mins in 50% polyamide resin and 50% anhydrous alcohol solvent under magnetic stirring at 40ºC. It depends on the temperature and percentage of polyamide resin. Q: Which one dried more quickly among co-solvent and alcohol-soluble polyamide resin? A: Co-solvent polyamide resin. Q: What is the formula weight? A: About 10,000. Q: Can you produce according to Air or Sunmide standard? A: Yes.
