Product Description

4,4′ – Methylene is (2-chloroaniline), also called MOCA, is a substance used as a crosslinking agent / chain extender for polyurethane products, especially for cast polyurethane elastomers (CPU). Polyurethane elastomers are flexible and posse elasticity nature like rubber but with significant properties, it combines high elasticity of rubber and rigidity of plastic. MOCA features with Color stability in high temperature. MOCA-base elastomers are good for abrasion / impact / chemical / oil / ozone and cold resistance, elasticity no matter with high or low hardness (Shore A to Shore D rating), high tensile / tear / compression strength, and absorption of vibration. With the long pot life, it’s very easy to handle with, you can even handle manually instead of by machines. Resulting from those physical properties and advantages, MOCA is the most common crosslinking / chain extender for urethane elastomers (TDI system). Meanwhile, it’s also a universal curing agent for Epoxy products.

Product properties & Features

Comparing to DETDA & DMTDA, there are some obvious advantages of MOCA as follows.

1. The finished product is lighter in Color.

2. MOCA is solid type, thus, it’s much easier to store and less pollution.

3. Easy to handle. Long pot life.

4. Modulus is higher.

5. Lower price.

MOCA is an aromatic diamine chain extender or curing agent that widely used in casting polyurethane elastomers, elastomeric pavement materials, PU waterproof coatings, PU adhesives, PU foams, etc.

The MOCA-chain-extended PU elastomers are widely applied in the areas including machinery, building, vehicles, transportation, mining industry, electronic components encapsulation and sport facility, etc.

MOCA can also be used in curing epoxy resin.

Our MOCA is high purity grade, the melt MOCA is colorless to yellowish transparent liquid, it is recommended used in the applications such as skateboard wheel, polyurethane rice hulling roller, scraper, light

Color PU coatings, etc. which require good property and almost colorless transparent in appearance.

Application

MOCA is a well-known aromatic diamine chain extender or curing agent for casting polyurethane (PU) elastomers. MOCA-base elastomers have excellent properties, are widely used in various areas including construction, building, vehicles, mining, semi-conductor, epoxy, sport facility and so on.

1. Bridging agent for electronic industry.

2. Waterproof material / coating for construction & architectural industry.

3. Chain extender for PU elastomers, i.e. jaw rubber coupling, PU spider.
