Properties: lt is synthesized by formaldehyde, modifying agent, active agent andparasubstituted alkylphenols which have diferent number of carbon atom in the alkyl groups.

Applications: Comparing to the SY1206 and SY1309, this ST-500B has the characteristics of long-term effective, nice moisture stability and high viscosity-promoting ability. Its viscosity-promoting ability is similar to para-tertbutylphenolaceylene resin and superior to para-tert-butylphenol (or para-tert-octylphenol) formaldehyde resin.

This product should be added under the temperature higher than its’ softening point in the early period of mixing, torse and to get the best viscosity-promoting effectiveness. lt can save the use level ofensure the resin’s homodisper processing oil to a certain degree. The recommended dosage is 2-5 phr.

Storage: Kept in dry and ventilating place, protected from heat and fire, the storage life is 12 months. The products that exceed storage life and qualified can be used.

Package: Packed in knited bags lined with a layer of kraft paper bag and a layer of plastic bag. The net weight is 25kg per bag.
