MOCA is an aromatic diamine chain extender or curing agent 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.

MOCA-HR is a special MOCA grade features with color stability at high temperature. The color of the melted MOCA-HR keeps light-yellow and clear almost without any changes after being heated several times, even though the heating temperature is up to 150℃. It is recommended applied in a variety of casting polyurethane elastomer parts especially manufactured with casting machines. The products have light color.

MOCA is a kind of widely used high cost effective aromatic diamine chain extender or curing agent for casting polyurethane elastomers, water-proof polyurethane coatings, elastomeric pavement materials, PU adhesives, PU foams, etc. The PU elastomers chain-extended with MOCA have excellent properties, are widely applied in the areas including machinery, building, vehicles & transportation, mining industry, electronic components encapsulation and sport facility, etc.

XYlink M-CDEA is an aromatic chain extender. It has good compatibility with TDI-based prepolymer. The reaction of M-CDEA and prepolymer is faster than that of MOCA. XYlink M-CDEA is recommended mainly used for high-performance casting polyurethane elastomers, and can also be used in RIM PUs, microcellular polyurethane elastomers, and spray polyurethane-ureas, etc.

XYlink ML-200 is a liquid aromatic diamine with similar molecular structure to MOCA. It could be looked as a chemical modified MOCA and can be mixed with NCO-capped prepolymer at lower temperature, showing better operation performance than MOCA. ML-200 reacts faster than MOCA.

XYlink ML-400 is a liquid aromatic diamine with molecular structure similar to halves of MOCA and 4,4\\\\\\\\\\\\\\\'-diaminodiphenylmethane(MDA). It can be looked as a chemical modified MOCA and can be mixed with NCO-capped prepolymer at lower temperature, showing better operation performance than MOCA. ML-400 reacts faster than MOCA.
