Chlorinated binder MP resin, also called Chlorinated MP Resins or VC copolymer resin. When its full name is Copolymer of Vinyl Chloride and Vinyl Isobutyl Ether.
In google translation, it is often translated into “Chloroprene resin”.
Initially, BASF's Laroflex MP 15, 25, 35, 45, and 60 grades were widely popular worldwide and had long been industry benchmark products. Therefore, domestic and international manufacturers and users commonly referred to these chloroprene resins as MP 15, 25, 35, 45, and 60. Our corresponding grade is iSuoChem CMP15, 25, 35, 45, and 60.
Anyway, MP resin is a chlorinated binder and has been developed as protective coatings for corrosion-resistant paints and printing inks.
The MP-25 model is mainly used in the coating industry.

MP-45 model is mainly used in the ink industry, but the final model shall be determined according to the customer's specific formula;
In addition, there are models such as MP-15, MP-35, and MP-60 to meet different performance requirements such as viscosity.
| MP Resin Model No. | Viscosity (mpa.s) |
| Chlorinated MP-15 |
Low viscosity 10-20 |
| Chlorinated MP-25 |
Medium to low viscosity 20-30 |
| Chlorinated MP35 |
Balanced viscosity 30-40 |
| Chlorinated MP45 |
Medium to high viscosity 40-50 |
| Chlorinated MP-60 |
High viscosity 55-65 |

Certifications: iSuoChem related MP 15, 25, 35, 45, and 60 resin has been approved by SGS, European REACH.
