Formaldehyde Stabilizer
PRODUCT INTRODUCTION
Formaldehyde Stabilizer is an organic chemical compound that is a member of the triazine family. It is a weak base that insoluble in water. It stabilizes formalin and prevents the polymerization of formalin high concentration when it is stored at room temperature.
Formaldehyde Stabilizer can be used to stabilize Formalin 48% when it is stored at room temperature or during shipping. The typical dosage recommendation of FORMALDEHYDE STABILIZER is about 0.1%. It can stabilize Formalin 48% up to 60 days at room temperature and can stabilize formalin 37% up to 36 days also formalin 42-45% up to 3 days at 4 ° C.
