MOCA Supplier in Malaysia for Polyurethane Curatives
- Also known as
- 4,4'-Methylenebis(2-Chloroaniline)
MOCA supplier in Malaysia for cast polyurethane elastomer and specialty resin processors. MOCA is 4,4'-methylenebis(2-chloroaniline), CAS 101-14-4 and formula C13H12Cl2N2, supplied as a pale yellow to amber crystalline solid, granules or pellets.
Standard industrial, low-colour and controlled-particle grades share the same aromatic diamine identity but differ in colour, particle form, moisture and impurity controls. Processors normally melt and meter the selected solid form according to their established formulation and cure cycle.
MOCA is used as a curing agent for cast polyurethane wheels, rollers, seals, liners, screens, bushes and other wear components, as well as selected resin systems. It is not an isocyanate, polyol or polyurethane resin, so MDI, TDI, prepolymer and MOCA requirements should remain separate.
Send the required grade, assay, colour, particle form, application, quantity and delivery location with your enquiry. Availability, packing, documentation and delivery timing are confirmed with the quotation. Supply is subject to applicable requirements.

MOCA grades and forms
We supply several forms to suit different formulating and dosing setups. If you need a size that is not listed, ask us.
| Grade | Form | Assay | Typical use | Packing |
|---|---|---|---|---|
| Standard industrial-grade MOCA | pale yellow to amber crystals, granules or pellets | — | Aromatic diamine curing agent for cast polyurethane elastomers and selected resin systems made to an established production specification. | Confirm the required pack format with the quotation. |
| Low-colour MOCA | pale crystalline granules or pellets | — | Cast polyurethane components where the producer controls curative colour, appearance and impurity profile more tightly for the finished article. | Confirm the required pack format with the quotation. |
| Controlled-particle MOCA | crystals, granules or pellets with an agreed particle profile | — | Metered melting and batch preparation processes where consistent particle size supports repeatable charging and heat-up behaviour. | Confirm the required pack format with the quotation. |

Safety and handling
Keep MOCA sealed in a cool, dry, well-ventilated area and protect it from moisture, heat and incompatible materials. Control dust and contact during handling, and follow the safety information for the quoted grade. Supply is subject to applicable requirements.
Common questions about MOCA
What does MOCA mean in polyurethane manufacturing?
MOCA is the established trade abbreviation for the aromatic diamine 4,4'-methylenebis(2-chloroaniline), CAS 101-14-4. It is used as a curing agent in cast polyurethane elastomer production and selected resin systems.
Is MOCA a polyurethane resin or an isocyanate?
No. MOCA is a curative that reacts within a specified polyurethane or resin system. It is separate from MDI, TDI, polyether polyols and prepolymers, so the enquiry should name each formulation component independently.
Which MOCA grade should a processor request?
Standard industrial grade suits established elastomer production, while a low-colour grade may be preferred when appearance controls are tighter. State any particle, assay, moisture, colour and impurity requirements used by the current process.
Why is MOCA supplied as crystals, granules or pellets?
The solid form affects charging, dusting and melting behaviour in batch preparation. Provide the handling system and preferred particle profile so the quoted form can be assessed against the process.
What specifications matter for MOCA?
Useful controls include chemical identity, assay, colour, moisture, melting behaviour, particle form and the relevant impurity profile. A current curative specification gives the clearest basis for grade matching.
What packing and documents are available for MOCA?
Packing is matched to the crystal, granule or pellet form and the site's charging method. List the required product and safety documents so both packing and documentation can be confirmed for the quoted MOCA grade.
What details are needed for a MOCA price in Malaysia?
Send the grade, physical form, specification, application, quantity and delivery location. Pricing is issued on enquiry with a stated validity period, and delivery timing is confirmed in the offer.
