Typical Properties
Rubber Accelerator ZMBT is light yellow powder with light bitter taste. Specific density is 1.65--1.72. Hardly soluble in acetone, benzene, ethanol, and carbon tetrachloride. Insoluble in water, gasoline. Rubber Accelerator ZMBT will be decomposed within strong acid and alkali.
In latex vulcanization Rubber Accelerator ZMBT is used in combination with Rubber Accelerator ZBEC, Rubber Accelerator ZDMC and Rubber Accelerator ZDEC. Rubber Accelerator ZMBT does not destabilize latex formulations.
In latex thread applications the low free MBT grade of Rubber Accelerator ZMBT provide reduced extraction of MBT during acid coagulation (acid bath pollution) and helps to stabilize the viscosity of latex compounds during storage.
In dry rubber applications the performance of Rubber Accelerator ZMBT is almost similar to MBT, but with a slight scorch improvement.

Store Rubber Accelerator ZMBT in a cool, dry, well ventilated area, avoiding exposure of the packaged products to direct sunlight.
Usually the shelf time is 24 months while the recommend use of date is in 12 months.
