Applications
Flame Retardant
Melamine Cyanurate (MCA) forms a layer of carbon foam when heated, minimizing contact between polymer and oxygen, slowing or stopping burning and reducing toxic fumes. Its high nitrogen content produces water steam and nitrogen gas at high temperature, reducing combustible gas concentration.
Lubricant
MCA's unique laminar crystal structure provides excellent lubricity, reducing friction and wear in mechanical systems. It is more cost-effective than traditional MoS₂ and PTFE, and is commonly used for high-performance greases and lubricants in automotive and industrial applications.
Matting Agent
As a matting agent, MCA is used in coatings to reduce gloss and deliver a matte effect. It has good adhesion with resin and better matting performance than titanium dioxide and silica.
Electroplating Additive
MCA improves the surface properties of plastics and increases their adhesion to metal layers during electroplating, making metal coatings on plastic parts more durable and uniform.
Concrete Additive
MCA can be used as a concrete additive to increase the strength of concrete, improve its overall performance, and extend its service life.
Cosmetic Covering Agent
MCA can be used as a covering agent in sunscreen and shaving cream. It is non-irritating to the skin, has good adhesion, and makes the product smoother.
Handling and Storage
Handling
- Avoid dust formation
- Follow the usual precautions for handling chemicals
Storage
- Follow the general rules of industrial fire protection
- Take precautionary measures against electrostatic charges — earthing necessary during loading operations
- Keep away from sources of ignition, because dust can form an explosive mixture with air
- Keep containers tightly closed, cool and dry
Packaging
Available in various packaging sizes, such as 25kg bags, bulk sacks, and other custom packaging solutions to meet specific requirements.
Frequently Asked Questions
QWhat is Melamine Cyanurate (MCA) and how is it produced?
Melamine Cyanurate (MCA) is a white crystalline powder synthesized by combining melamine and cyanuric acid. The resulting compound is stable, non-toxic, and widely used across industries as a flame retardant, lubricant, matting agent, and various other additives.
QHow does MCA work as a flame retardant?
When heated, MCA forms a protective layer of carbon foam that minimizes contact between the polymer and oxygen, thereby slowing or stopping combustion and reducing toxic fumes. Its high nitrogen content also generates water steam and nitrogen gas at elevated temperatures, diluting combustible gases and further improving flame retardant performance.
QIs Melamine Cyanurate safe for use in consumer products?
Yes. MCA is non-toxic and environmentally friendly. It contains no harmful halogenated byproducts, making it safe for use in consumer products including cosmetics such as sunscreen and shaving cream. It is non-irritating to the skin and provides good adhesion and a smooth texture.
QWhat are the advantages of using MCA as a lubricant compared to MoS₂ and PTFE?
MCA's unique laminar crystal structure provides excellent lubricity, effectively reducing friction and wear in mechanical systems. Compared to traditional lubricants like molybdenum disulfide (MoS₂) and polytetrafluoroethylene (PTFE), MCA is more cost-effective while delivering comparable or superior performance in high-performance greases and lubricants for automotive and industrial applications.
QWhat packaging options are available for Melamine Cyanurate?
MCA is available in various packaging sizes including 25kg bags, bulk sacks, and other custom packaging solutions designed to meet specific customer requirements and logistical needs.
QWhat precautions should be taken when handling and storing MCA?
During handling, avoid dust formation and follow standard chemical handling precautions. For storage, keep MCA away from ignition sources as dust can form explosive mixtures with air. Store containers tightly closed in a cool, dry location, follow industrial fire protection guidelines, and take precautionary measures against electrostatic charges — earthing is required during loading operations.
