Specifications for Liquid MOCA

Liquid MOCA is Mixture of 4,4'-Diamino-Diphenyl Methane, MOCA and TRIS.

As we have mastered defferent techniques to produce MOCA, quality can be made according to the customer's requirements.

Naturally, liquid MOCA is pot life is much shorter than solid MOCA, we can product liquid MOCA with Pot Life range between 30 seconds to 3 minites at different viscocity.
Liquid MOCA is more worker friendly than solid MOCA. It is suitable for curing natural rubber and synthetic rubbers.
