  • Optical Brightener ST-1

    Optical Brightener ST-1

    This product is used at room temperature to within 280℃, can degrade 80 times of soft water, acid and alkali resistance is pH = 6~11, it can be used in the same bath with anionic surfactants or dyes, non-ionic surfactants, and hydrogen peroxide. In the case of the same dosage, the whiteness is 3-5 times higher than that of VBL and DMS, and the alignment energy is almost the same as that of VBL and DMS.

  • Optical Brightener ST-2

    Optical Brightener ST-2

    ST-2 high-efficiency fluorescent whitening agent can be arbitrarily dispersed in soft water, acid and alkali resistance is pH=6-11, it can be used in the same bath with anionic surfactants or dyes, non-ionic surfactants, and hydrogen peroxide. Used in coatings, organic salts are incompatible with organics, and the coatings are easy to migrate and yellow after drying.
