MOCA (CAS 101-14-4) is 4,4′-methylenebis(2-chloroaniline). MBOCA is the same substance. It is different from MDA (CAS 101-77-9, without chlorine), from MCDEA, from diethyltoluenediamine (DETDA) and from the prepolymers it cures. Please quote the CAS number.

Share the assay, form (pastilles or granules) and packing, quantity, packing, Incoterm and delivery Emirate through our contact page and our team aims to respond within one business day.

Typically 25 kg lined drums or bags, with smaller sealed packs for trials. Packs are sealed against moisture and air and labelled for toxic-substance transport as per the SDS.

The minimum order depends on packing and current stock. We handle everything from a few drums or small packs for trials and lab qualification up to full container loads.

Store in tightly closed containers in a cool, dry, well-ventilated place, protected from light and away from oxidisers, acids and nitrating agents. Reseal opened packs promptly because the product darkens in air.

Yes. MOCA is harmful if swallowed, may cause cancer and is very toxic to aquatic life. It can be absorbed through the skin, so closed handling, protective equipment and health surveillance are essential. Follow the SDS and local exposure rules.

Yes. We export from the UAE to Saudi Arabia, Oman, Qatar, Kuwait, Bahrain, East and West Africa, South Asia and other markets on EXW, FOB, CFR, CIF, DAP or DDP terms, subject to the import rules of each destination.

Yes. Samples are available for qualification on request, together with the COA and SDS, so your QC or R&D team can approve the material before a commercial order.

In several jurisdictions MOCA is a listed substance of very high concern or subject to authorisation, and many sites have strict exposure controls or use alternative curatives. We supply only against documented industrial end use and in line with UAE and destination-country rules, so please share your company and application details with the enquiry.

Water reacts with the isocyanate in the prepolymer and releases carbon dioxide, which forms bubbles and weakens the cast part. That is why MOCA is supplied dry and sealed, and why moisture is a key item on the COA.
