Advantages and applications：
When it comes to the field of polyurethane rubber and coatings, finding the right vulcanizing and crosslinking agent is crucial. This is where MOCA (4,4’-Methylene-Bis-(2-Chloroaniline)) takes center stage. With its exceptional properties and wide range of applications, MOCA has become a staple in various industries.
MOCA is known for its appearance as white to light yellow loose needle crystal, which turns black when exposed to heat. Additionally, it possesses slight hygroscopic properties and is soluble in ketones and aromatic hydrocarbons. These characteristics make it an ideal candidate for use in different manufacturing processes.
One of the key benefits of MOCA is its role as a vulcanizing agent for cast polyurethane rubber. By crosslinking the polymer chains, MOCA enhances the strength and durability of the rubber. This ensures that the final product can withstand harsh conditions and maintain its integrity for a longer period of time.
Furthermore, MOCA serves as an excellent crosslinking agent for polyurethane coatings and adhesives. It promotes chemical bonding between the polymer molecules, resulting in coatings and adhesives that exhibit superior performance. Whether it’s for protective coatings or structural adhesives, MOCA provides the necessary strength and stability.
In addition to its applications in rubber and coatings, MOCA can also be used for curing epoxy resins. By adding small amounts of MOCA, the epoxy resin can undergo a crosslinking reaction, leading to improved mechanical and thermal properties. This makes MOCA a valuable tool for industries that rely on epoxy resins for their products and applications.
Furthermore, there is a liquid form of MOCA known as Moka. This variant can be used as a polyurethane curing agent at room temperature, making it highly convenient for production processes. Additionally, Moka can serve as a polyurea curing agent for spraying applications. Its versatility and ease of use make it a popular choice among manufacturers.
Packaging and storage：
Packaging:50kg/DRUM
Storage：should be at cool, dry and ventilate.
Stability:Heating and turning black, slightly humidity. There is no detailed pathological test in China, and it is not sure that this product is toxic and harm. The device should be strengthened to reduce the contact with the skin and inhale from the respiratory tract, and minimize the harm to the human body as much as possible.
Summary：
To sum it up, MOCA (4,4’-Methylene-Bis-(2-Chloroaniline)) is a highly versatile and valuable vulcanizing and crosslinking agent. Its wide range of applications in the polyurethane rubber, coatings, and adhesives industry makes it a go-to choice for manufacturers. With its ability to enhance strength, durability, and chemical bonding, MOCA undoubtedly plays a crucial role in ensuring the quality and performance of various products.
