1. COUPLING AGENT
(MPOL-MC520)

2. 1. General Information for MPOL-MC520
Coupling Agents is reactive multi-functional monomer which are composed of organic functional group bonding organic materials and inorganic functional group reacting with inorganic materials in molecule. They take advantage of reforming organic and inorganic complex, namely improvement of mechanical strength, chemical resistance, and water resistance by carrying out combination each other in organic and inorganic materials.

6. Increasing coherence of organic resins and inorganic fillers
5. Mpol-MC520
It is organic and inorganic complex compound which is composed of mono or multi functional
acryl monomer and phosphorous compound. Increasing coherence and dispersibility between
organic resins and inorganic fillers, it improve mechanical and chemical strength such as durability,
corrosion resistance, abrasion resistance and chemical resistance, etc. It is eco-friendly products
which are demonstrating function of high gloss without using heavy metal and is widely used for
oil-soluble ink, paint, electric steel sheet etc.
Characteristics of products
